Significance of Serum Biomarkers in Early Diagnosis of Hepatocellular Carcinoma in Patients with Fisher Groups

Introduction: This study investigates the relationship between serum biomarkers and the detection of hepatocellular carcinoma (HCC) in different fisher groups in Bangladesh. The research adopts a descriptive and experimental approach to demonstrate the health risks faced by fishermen, including tobacco consumption, polluted drinking water, and insufficient sunlight exposure. Method: We used serum biomarkers such as vitamin D, alpha-fetoprotein (AFP), creatinine (Cr), and hemoglobin A1C (HbA1c) to evaluate their significance in distinguishing between different categories and sexes. Result: We determined a strong and direct correlation between insufficient vitamin D levels and an increased risk of liver cancer. The combination of AFP, vitamin D, and Cr (AFP+Vit-D+Cr) emerges as a highly predictive tool, enhancing diagnostic accuracy and providing a reliable means of identifying hepatocellular carcinoma. Conclusion: The identified correlation showed the significance of addressing lifestyle factors and promoting nutritional support to mitigate the risk of liver cancer among fisher groups. The AFP+Vit-D+Cr combination is a promising diagnostic tool for hepatocellular carcinoma, offering an improved early detection and intervention approach.

Construction of action in the structure of punggawa-sawi relationship in Burung Loe Island, Indonesia

he construction of performance in the patron-client structure that functions as a socio-cultural agent in the management system and the utilization of fisheries resources is inseparable from the norm system practices carried out repeatedly in fisher groups. The study uses a qualitative approach to identify the construction process of performance through the practice of norms, ideas, and arenas of fisher's struggle (courtier). The study was conducted in Burung Loe Island, Sinjai Regency. Data obtained through observation, in-depth interviews, and focus group discussions (FGD) with large punggawa (ship owner), small punggawa (fisheries operational leader) and the crew. The results show that the social practices of electric fishers (pa'bagang rambo), tuna-mackerel fishers (pa'tongkol) and cages/aqua culture (keramba or fish farming) did not just happen, but were conditioned by nature and market logic would build them to choose the appropriate job. Fishers are bound by schemes of perception and thought that seem to be a collective phenomenon in the form of rituals and safety norms so that they are safe, calm, and get abundant wealth. The arena of fisher actualization is conditioned by the social structure of the punggawa who creates a patron-client dichotomy.

Factors influencing risk perception of inshore and offshore artisanal fishers in a marine protected area in Brazil

AbstractArtisanal small‐scale fisheries are crucial for subsistence and food security, especially in developing countries. However, artisanal fishers face stressors, such as economic and social marginalization, conflicts, and overfishing. Socio‐economic attributes potentially influence their risk perception. We investigated risk perception among artisanal fishers in a Marine Protected Area through interviews and semi‐structured questionnaires. Risk perception was positively influenced by fishing environment and negatively influenced by a lack of religious beliefs. Offshore fishers faced more operating conditions and time at sea, with higher risk of losses, and perceived more health and conflict risks. Inshore fishers have higher perception of environmental degradation. Prioritizing different risk perceptions is essential for effective fisheries management. Separate management plans for offshore and inshore fisheries are recommended due to varying catch, environmental perception, socio‐environmental risks, and exploited resource characteristics among artisanal fisher groups.

De-hooking depredation: Exploring multiple fisher perceptions about marine depredation in Florida

Marine depredation involves the removal of or damage to captured fish by predators, and recent evidence suggests it is increasing globally likely due to increasing fishing effort and changes in predator behavior. Anecdotal reports indicate that marine depredation in Florida may be especially severe, given the high number of fishers and predator species. However, the magnitude of marine depredation in Florida and fisher perceptions of these events are poorly understood. We employed a survey of commercial, private recreational, and for-hire saltwater license holders to explore the extent and magnitude of fishing experiences and perceptions related to marine depredation across Florida, highlighting differences among fisher groups using closed- and open-ended survey questions. We found few to no significant differences between fishing sector groups, meaning depredation was prevalent across all locations, gear types, and target species. Most user groups experienced depredation by more than one predator, but sharks and dolphins were reported as the most common predators. Commercial and for-hire operators were more likely to have very negative and negative sentiments toward predators, while private recreational fishers were more likely to view their depredation experiences as neutral. The need for improved management of predators and other fish stocks was expressed across all sectors, especially among commercial fishers. Our results support the growing literature on increased depredation experiences statewide and the need to devise a solution for all marine fisheries users in Florida. We anticipate our exploratory findings to be used as a starting point for researchers and fisheries management agencies to understand fishing sector perceptions and attempt to mitigate negative depredation experiences.

Fisheries in a border area of the Moxos Lowlands (Bolivia) after invasion of Arapaima gigas

AbstractFish in the upper Madeira River basin (Bolivian Amazon) are an important source of livelihoods and protein for both rural and urban human populations. We characterised fisheries in the area of the port city of Riberalta, which possesses some of the most important fisheries landing sites bordering the Moxos lowlands, and evaluated the contribution of an invasive species (Arapaima gigas) to the landings. We compared the regional economic contribution of urban‐based and rural indigenous fisheries. Both fisheries contribute significantly to local food security and livelihoods and take advantage in a different but complementary way of the abundance of the invasive species, avoiding conflicts by partitioning the fish catch and supplying different urban markets. Both fisher groups are involved in a debt peonage system making them dependent on middlemen. A. gigas represented 57.6% of the overall economic value of fish in the region. The socioeconomic impact of the invasive species might increase considerably if it would invade and colonise the available habitats in the nuclear area of the Moxos lowlands.

Perceptions towards governance of billfish resource use: The lens of artisanal fishers in Kenya

Multiple fisher groups target billfish species, each with different motivations and experiences, which can influence the effectiveness and sustainability of governance approaches. However, limited studies underscore the perceptions of billfish resource users in defining and implementing governance in the Western Indian Ocean region. We conducted 211 semi-structured qualitative interviews between December 2020 and September 2021, to explore how artisanal fishers perceive the performance and sustainability of governance approaches in Kenya, with a focus on billfish. Our findings show that artisanal fishers have adequate knowledge of fishing laws and regulations, as well as governing institutions and their performance. Further, artisanal fishers had a positive attitude and support for fishing rules, managing institutions, and effectiveness of governance intervention. Specifically, the fishers rated Beach Management Units (BMUs) as highly effective in implementing fisheries rules, indicating the involvement of fishers in co-management of fisheries and tendency for governance success and sustainability. This highlights the need to strengthen and support BMUs as an effective governance tool in the co-management of fisheries. We draw attention to our first-time study of the contribution of artisanal billfish fishers to governance of shared fisheries resources. We show that involvement of resource users promotes a bottom-up approach to the co-management of billfish which compliments the current regional and national efforts that have largely focused on commercial fisheries. Our research adds to the scientific body of knowledge on the importance of perceptions in the formation of natural resource governance interventions at varying scales, especially for transboundary species in data-poor areas.

Fisher–shark interactions: A loss of support for the Maldives shark sanctuary from reef fishers whose livelihoods are affected by shark depredation

AbstractTargets for protecting predatory species often fail to consider the human costs of conservation. Human–wildlife interactions can increase following conservation action and present a major ecological and socioeconomic challenge. Using semistructured interviews (n = 103), participatory mapping (n = 57) and Baited Remote Underwater Video Stations (50 h) we investigated fisher‐shark interactions in one of the world's principal shark sanctuaries. Seventy‐three percent of respondents reported an increase in shark depredation postsanctuary implementation. Fisher‐reported losses due to shark depredation varied significantly between fisheries and were disproportionately high for reef fishers (>21% of daily vessel earnings). This is attributed to extensive spatial overlap (55%–78%) between reef fishing activity and ecologically validated shark hotspots. We show significant correlations between perceptions of depredation and support for shark sanctuary regulations. Findings demonstrate the need to consider fisher–shark interactions in current and future conservation planning and suggest that management of depredation must be sensitive to diverging perceptions among fisher groups.

Association between Traumatic Subarachnoid Hemorrhage and Acute Respiratory Failure in Moderate-to-Severe Traumatic Brain Injury Patients.

Acute respiratory failure (ARF) with a high incidence among moderate-to-severe traumatic brain injury (M-STBI) patients plays a pivotal role in worsening neurological outcomes. Traumatic subarachnoid hemorrhage (tSAH) is highly prevalent in M-STBI, which is associated with significant adverse outcomes. In this retrospective cohort study, we aimed to explore the association between the severity of the tSAH and ARF in the M-STBI population. A total of 771 subjects were reviewed. Clinical and neuroimaging data of M-STBI patients were retrospectively collected, and ARF was ascertained retrospectively based on their electronic medical record. The degree of tSAH was classified according to Fisher’s criteria, and the grade of tSAH was dichotomized to a low Fisher grade (Fisher grade 1–2) and a high Fisher grade (Fisher grade 3–4). After exclusion procedures, the data of 695 M-STBI patients were analyzed. A total of 284 (30.8%) had a high Fisher grade on admission. The overall rate of ARF within 48 h upon admission was 34.4% (239/695); it was 29.5% (142/481) and 46.3% (99/214) for the low and high Fisher groups, respectively. In a full cohort, a high Fisher grade was associated with ARF after adjusting for age, gender, GCS, smoking history, comorbidities, multiple injuries, characteristics of TBI, and pulmonary factors (OR 1.78; 95% CI, 1.11–2.85, p = 0.016). This result remained robust in the comparisons after PSM (71/132, 42.8% vs. 53/132, 31.9%; OR, 1.59; 95% CI, 1.02–2.49, p = 0.042). A high Fisher SAH grade exposure on admission is associated with ARF in M-STBI patients.

Can producer groups improve technical efficiency among artisanal shrimpers in Nigeria? A study accounting for observed and unobserved selectivity

It is widely recognized that participation in producer groups is advantageous for smallholders who must deal with complex production and marketing constraints and dynamic business environments. However, available data on this process are scarce in the fishery sector, while existing evidence is limited by smallholders’ potential self-selection into producer groups. This study, therefore, examined the selectivity-corrected role of fisher groups in improving shrimpers’ technological and technical efficiency. Using the latest primary data from artisan shrimpers in Nigeria, we applied propensity score matching and Greene’s selectivity stochastic production frontier model to control for selection bias from both observable and unobservable factors. Empirical results from our metafrontier approach show that technical efficiency scores for members tend to be overestimated if selectivity is not properly controlled. However, the technical efficiencies and productivities of members were significantly higher regardless of how biases were corrected, implying that participation in fisher groups is positively related to increases in shrimpers’ capture and technical efficiency. Further findings suggest that current artisanal fisher groups are “production-oriented” as they ensure that members access vital shrimping inputs at lower costs. With declining returns to scale for members, the study concludes that without public and private support for collective action in the fishery sector, membership in artisanal fisher groups may not lead to significant improvement in shrimpers’ productivity. The study discusses several recommendations on how collective action can be further encouraged and developed among artisan fishers.

Neo-liberal or not? Creeping enclosures and openings in the making of fisheries governance

Neo-liberalism can mean different things from different perspectives. Social scientists tend to use the concept to identify and critique trends of privatization, marketization, commodification and enclosures, and their associated slew of exclusionary, dispossessive, and regressive effects. Counterintuitively, governmentality analyses identify how practices of collaboration, inclusion, participation, and empowerment—practices sometimes cited as means to resist and generate alternatives to neo-liberalism—are not only consistent with neo-liberal governing but also central to its functioning. This paper engages a biopolitics and governmentality analytical perspective to examine different kinds of fisheries policies in Newfoundland and Labrador (NL), Canada, where the historic cod collapse created a laboratory for examining social-ecological effects of capitalist overexploitation, resource mismanagement, and knowledge system blind spots. The case is useful because it includes, on the one hand, practices traditionally seen as reinforcing neo-liberal governance, such as property making, resource management access rationalization, and global eco-labels, and, on the other hand, practices where linkages to neo-liberalism require more critical assessment, such as fisher-influenced professionalization policies, license collaboration/consolidation initiatives, and producer-oriented eco-labels. Drawing on a governmentality perspective, this paper examines how governance change in NL fisheries is driven not by a single regulatory logic but, rather, by diverse “technologies of government” and “technologies of agency.” Diverse technologies of agency, with varying degrees of links to neo-liberalism, facilitate “creeping” enclosures and openings for fish harvesters in NL fisheries. The paper finds that multi-faceted social protection and coastal community-oriented rationalities of fisher groups are key explanatory variables in shaping practices for and against neo-liberal governance, suggesting that the relationship of diverse neo-liberal, moral economy and hybrid governmentalities to lived experiences requires more empirical and theoretical attention.

A comparative study of sustainability profiles between small-scale mariculture, capture fisheries and tourism communities within the Anambas Archipelago Small Island MPA, Indonesia

Mariculture is viewed by some as an unsustainable economic activity in marine protected areas (MPAs). Surprisingly, no study has confirmed or rejected the veracity of the view. In Indonesia's multi-purpose MPAs, mariculture is considered as part of the local communities' livelihood and resilience strategy. This study aimed to determine whether small-scale fish farming, along with small-scale fisheries and eco-tourism, contributes to the livelihood sustainability of communities in Indonesia's small island MPAs, and if the practice is compatible with the overall MPA objectives. The study was conducted in the Anambas Archipelago MPA and interviewed 66 respondents from three household groups (small-scale fish farmers, fishers, and eco-tourism operators) from 15 villages. A closed- and open-ended questionnaire was developed to determine the sustainability profile of each livelihood group. The questionnaire consisted of 75 questions representing the sustainability indicators (SIs) of the five capital assets described in the Sustainable Livelihoods Framework (SLF). The SIs were measured using a Likert-scale and a Likert-type scale with multiple scales. The data were standardised using linear transformation and aggregated to calculate the SIs composite values. The study found that the livelihood sustainability of the small-scale fish farmer group is comparable to small-scale fisher and tourism operator groups. Interestingly, the fish farmer group outperformed the other two groups in relation to human capital assets by developing a strong social network. Small-scale fish farmer, fisher and eco-tourism operator groups have a composite sustainability index value of 0.55, 0.61, and 0.50, respectively, categorised as intermediate sustainability. This study concluded that the sustainability profile of each livelihood group could be improved for the specific underperforming capital assets by increasing support from the government and MPA authority.

Local disconnects in global discourses—The unintended consequences of marine mammal protection on small‐scale fishers

AbstractGlobal commitments prioritize protection of wildlife and improvements to human wellbeing. Local disconnects in these commitments are rarely acknowledged—or their implications assessed—preventing the development of effective solutions. National and international efforts to protect marine mammals along South America's west coast have contributed to species recovery, but also to conflict between sea lions and small‐scale fisheries. To understand the concerns ultimately motivating this conflict, we assessed how 301 coastal small‐scale fishers perceive their interactions with South American sea lions (Otaria flavescens). We then reviewed the terrestrial human–wildlife literature to identify potential management solutions to resolve the conflict. We find that fishers are chiefly concerned with increases in sea lion populations, perceive that sea lion interactions have significantly increased over the past 80 years, and report sea lion‐driven catch and income losses of ≥26%. We propose solutions to manage conflict that are sensitive to heterogeneity among fisher groups.

Determining management preferences in a multimethod consumptive recreational fishery

Understanding behavioral responses of recreational fishers to management changes is fundamental for effective policy making. However, given the diverse motivations and nonmarket nature of recreational fishing, evaluating fishers’ preferences is nontrivial. This study examined fishers’ management preferences toward different management tools (i.e., a new measure or a change in the setting for an existing measure) in a highly consumptive recreational fishery. A combination of a discrete choice experiment and an opinion-based survey explored the potential heterogeneity in management preferences in the Tasmanian Rock Lobster fishery. Although the fishery has extensive management in place, further restrictions are required to limit recreational harvest in support of a strategy to achieve a stock rebuilding target. As a diverse fishery, with various fishing methods and a range of activity levels, it is expected that the perceptions of management changes vary across fisher subgroups. A phone survey was used to ask fishers’ opinions on how effective different management tools are at restricting catch and if they supported or opposed the tool. Additionally, a discrete choice experiment was used to assess if fishers’ utility is associated with a management tool and to what extent fishers are willing to trade a change in one management tool for a change in another. Results show that there are both homogenous and heterogeneous management preferences in the fishery across fisher subgroups. There was consensual aversion by all fisher subgroups toward changes in management settings that directly limit the catch of lobster, including a reduction in daily bag limit and shortened season length. Other changes to management settings, such as an increase in the minimum size limit, have less consensus in preference between fisher groups, and any changes in these tools could differentially impact fisher subgroups. The results from this research can support managers in identifying whether and to what extent intra-sector separation for the purposes of designing and implementing new management measures and settings is warranted, on the basis that it can increase effectiveness of achieving management and the likelihood of maximizing net utility within a fishery.

Evaluating approaches for scaling-up community-based marine-protected areas into socially equitable and ecologically representative networks.

Marine-protected areas (MPAs) are vital to marine conservation, but their coverage and distribution is insufficient to address declines in global biodiversity and fisheries. In response, many countries have committed through the Aichi Target 11 of the Convention on Biological Diversity to conserve 10% of the marine environment through ecologically representative and equitably managed MPAs by 2020. The rush to fulfill this commitment has raised concerns on how increasing MPA coverage will affect other elements of Target 11, including representation and equity. We examined a Philippines case study to assess and compare 3 MPA planning approaches for biodiversity representation and equitable distribution of costs to small-scale fishers. In the opportunistic approach, MPAs were identified and supported by coastal communities. The donor-assisted approach used local knowledge to select MPAs through a national-scale and donor-assisted conservation project. The systematic conservation planning approach identified MPA locations with the spatial prioritization software Marxan with Zones to achieve biodiversity objectives with minimal costs to fishers. We collected spatial data on biodiversity and fisheries features and performed a gap analysis to evaluate MPAs derived from different approaches. We assessed representation based on the proportion of biodiversity features conserved in MPAs and distribution equity by the distribution of opportunity costs (fishing areas lost in MPAs) among fisher stakeholder groups. The opportunistic approach did not ineffectively represent biodiversity and resulted in inequitable costs to fishers. The donor-assisted approach affected fishers disproportionately but provided near-optimal regional representation. Only the systematic approach achieved all representation targets with minimal and equitable costs to fishers. Our results demonstrate the utility of systematic conservation planning to address key elements of Target 11 and highlight opportunities (e.g., integration of local and scientific knowledge can address representation and equity concerns) and pitfalls (e.g., insufficient stakeholder considerations can exacerbate social inequalities) for planning MPAs in similar contexts.

Specialization of fishers leads to greater impact of external disturbance: Evidence from a social-ecological network modelling exercise for Sechura Bay, northern Peru

Coastal marine resources provide livelihoods to human communities around the world. The interactions in respective social-ecological systems are usually of complex nature, due to a wide range of different fisheries interacting with the ecosystem. Understanding connectivity within these systems (i.e. among social and ecological actors) helps in establishing meaningful management strategies for sustainable use of marine resources. This work uses the value chain analysis of different fisheries sectors to construct a qualitative social-ecological network (SEN) model of the Sechura Bay in North Peru. Here, a diverse ensemble of small-scale fisheries co-exists with a flourishing mariculture sector, though the respective production chains partially overlap. Directed and unweighted links between actors were defined based on the transfer of biomass (trophic interactions) and money (economic interactions). Several analytical network tools were applied (e.g. degree centrality, dominator tree) to identify the most important nodes of the social-ecological network and to understand interdependencies. Results of the network analysis suggest position of system's components being related to their vulnerability in the face of external disturbances. Fisher groups with a high specialization with respect to fisheries target species were stronger impacted by the last strong El Niño event (the Coastal El Niño 2017), with drastic consequences for actors of the respective production chains. The present approach is envisioned to be applicable beyond this particular case study and to nourish on-going scientific discussions on the use of social-ecological network analysis to describe human-nature interactions. This study allows (i) estimating node (actor) susceptibilities to natural and anthropogenic disturbances, and (ii) reconciling sustainable resource use and nature conservation by enhancing the understanding of the functionality of the respective social-ecological system.

Fishers’ Local Ecological Knowledge (LEK) on Connectivity and Seascape Management

In developing countries where data and resources are lacking, the practical relevance of Local Ecological Knowledge (LEK) to expand our understanding of the environment has been highlighted. The potential roles of the LEK varies from direct applications such as gathering environmental information to a more participative involvement of the community in the management of resources they depend on. Fishers’ LEK could therefore be useful in order to obtain information to advance management of coastal fisheries. Many targeted fish species migrate between habitats to feed, spawn or recruit, connecting important habitats within the seascape. LEK could help provide answers to questions related to this connectivity and the identification of fish habitat use and migrations for species and areas where such knowledge is scarce. Here we assess fishers’ LEK on connectivity between multiple habitats within a tropical seascape, investigate the differences in LEK among fisher groups and the coherence between LEK and conventional scientific knowledge (CSK). The study was conducted in Zanzibar, Tanzania, a tropical developing country, in 2017. One hundred and thirty-five semi-structured interviews were conducted in six different locations focusing on fish migrations, and matching photos of fish and habitats. Differences between fisher groups were found, where fishers travelling further, exposed to multiple habitats, and fish with multiple gears had a greater knowledge on connectivity patterns within the seascape than those that fish locally, in single habitats and with just one type of gear. A high degree of overlap in LEK and CSK was found, highlighting the potential benefits of collaboration between scientists and fishers and the use of LEK as complementary information in the management of small-scale fisheries.

A case of nonvenereal treponematosis in a pre‐Hispanic adult from north‐eastern Argentina

AbstractThis article presents a case of treponemic disease in a skeleton of a female adult found at Los Tres Cerros 1 archaeological site (Upper Delta of Paraná River, Entre Ríos, Argentina). This site was occupied by hunter–gatherer–fisher groups that also practised horticulture during the Late Holocene (ca. 1227–560 years BP). A macroscopic description of bone lesions is complemented with data from X‐rays and CT scans. Different types of lesions were observed in the left ulna, femora, right patella, tibiae, and fibulae. In addition, two remodelled depressions surrounded by bony thickening and porosities were found in the frontal bone. Some lesions registered in the skull were associated with caries sicca. In the differential diagnosis, chronic leg ulcers, Paget's disease, tuberculosis, leprosy, osteomyelitis, and treponematosis were considered. The analyses indicate that most of the injuries may be compatible with nonvenereal forms of treponematosis. Few cases of treponemic disease were recorded in Argentina's bioarchaeological collections of pre‐Hispanic populations. Specifically, in the north‐eastern region, two skeletons with treponematosis have so far been reported. The present study provides new evidence of treponematosis in the Delta of the Paraná River. Therefore, this case adds to the scant evidence of pre‐Hispanic treponematosis that exists for these latitudes.

Discriminating Catch Composition and Fishing Modes in an Artisanal Multispecies Fishery

Many small-scale fisheries are multi-species, and the catch composition can vary according to available habitats, fishing modes and fisher groups. Here, we applied novel approaches for understanding the factors affecting differences in catch composition among fishers, which should be useful for planning regulatory measures and fishery development initiatives. Interviews with 235 artisanal fishers in Fiji were used to analyse how fishers’ catch composition of 22 species of sea cucumbers varied across geographic scales (locations and villages within locations), genders and fishing modes. Venn diagrams illustrated that gleaning and SCUBA diving were practised to varying extents among locations and genders, whereas fishers used breath-hold diving more uniformly across the fishery. Segmented bubble plots revealed spatial variations in catch composition across the fishery. A PERMANOVA analysis found that species catch composition varied most across both geographic scales and, secondarily, among fishing modes and between genders. Gendered differences in catch composition were variable from one village to another, and so should not be generalised. SIMPER analyses showed that gleaners and SCUBA divers caught significantly different suites of sea cucumber species. Species threatened with extinction were among those typifying catches of SCUBA divers. Our novel graphical techniques are useful for visualising fishing modes and catches across other fisheries. Artisanal fisheries may exhibit strong heterogeneity in catch at multiple spatial scales. Planning of regulatory measures that limit certain fishing modes or species should take into account the likely differential impacts on different fishing communities and genders.

Investigating Stakeholder Perceptions of Fish Decline: Making Sense of Multiple Mental Models

Stakeholders have different educational backgrounds, personal experiences and priorities that contribute to different perceptions about what causes natural resource decline and how to sustain a resource. Yet stakeholders have a common interest, which is to keep the resource of interest from declining. Effective co-management requires sharing of perceptions pertaining to the sustainability of a resource and making decisions that benefit all stakeholders. Therefore, this study used modified causal networks, referred to here as mental models, to elicit and compare stakeholder perceptions about fish decline in the Danajon Bank, Philippines. Perceptions were elicited from three types of stakeholders, each composed of two or three elicitation groups: fishers, local government and environmental organizations. Data were also elicited through semi-structured discussions to investigate why perceptions differed and how stakeholders communicated with one another. Hierarchical clustering revealed two broad clusters of similar perceptions about drivers of fish decline: one being environmental groups and the second being local government and fisher groups. Stakeholder communication patterns revealed that communication was weakest between environmental groups and fishers. A likely contributing factor for the lack of shared perceptions was that knowledge-sharing was constrained by the small number of environmental personnel available to exchange information effectively with the much larger number of fishers and local government personnel. To better co-manage fish populations in Danajon Bank, we suggest modifications to the governance framework to improve knowledge-sharing and social and ecological outcomes.

Actividades tecnológicas articuladoras: una interpretación fértil del paisaje desértico costero de Arica (Chile)

El siguiente trabajo propone que la tecnología en fibra vegetal fue un eje articulador de decisiones sociales y tecnológicas ejecutadas por grupos de Cazadores-Recolectores y Pescadores tempranos de Arica (CRP). Esto en el marco de los procesos tecnológicos desplegados para la manufactura de artefactos sobre esta materia prima entre ca. 10000-3700 AP. Para concretar la propuesta se efectuó un análisis de los atributos técnicos-textiles de artefactos en materia vegetal provenientes de sitios de la costa ariqueña, un registro actualísitco de artesanías en materias vegetales que incluyó la identificación de etapas de manufactura y un mapeo de la cubierta vegetacional mediante teledetección. Lo anterior se sustenta teóricamente mediante el uso operacionalizado del concepto taskscape, nutrido con nociones sociales de tecnología y con el modelo de chaîne opératoire para así integrar a esta tecnología en el escenario social. Como conclusión, se logra definir que la manufactura fue parte del orden cotidiano de estos grupos que tras habitar continuamente estuarios y humedales transformaron de manera constante el entorno natural/cultural. Por ende, la extracción-selección, procesamiento y tejido conforma solo una fracción de una actividad social relevante que permite comprender aspectos sociales y tecnológicos que van más allá de la mirada del fitness alimenticio.
