Resilience to climate change among small-scale fishery on the Northern Coastal of Bengkulu Province, Indonesia

Climate change has become a global phenomenon and has become the focus of world attention. The resilience of fishermen in facing climate change shows the ability of fishermen to respond, organize, learn and adapt in the face of climate change. The purpose of this study is to analyze the livelihood resilience of small fishermen in the face of climate change based on three main indicators, namely buffer capacity, self-organization, and learning capacity. A total of 300 fishermen were selected using quota sampling and interviewed through a structured questionnaire. Data were analyzed using the descriptive and livelihood resilience index to explain the fishermen's resilience. The findings indicate that most fishermen in the coastal area of Bengkulu have a low level of livelihood resilience. The dimension of fisherman's learning capacity needs to be improved to strengthen livelihood resilience. Ecological, social, and economic adjustments to the capture fisheries business system in response to climate change can help fishermen in increasing their adaptive capacity and livelihood resilience is highly dependent on the ability and experience of fishermen in adapting.

Financial feasibility of hand line fisheries and determination of tuna production in Ambon Island

The potential availability of fish resources can be utilized in various economic activities to improve the welfare of coastal communities. The utilization of tuna by using hand line is still carried out by small and medium scale fisheries with some limitations, such as technical production, costs and management skills. The purpose of this study was to describe the technical profile of tuna fishery production in Ambon Island, specifically in Negeri Tial and Negeri Laha; analyze the absolute profit level of tuna fishermen; analyze hand line fisheries business feasibility; and determine the efficient fishing input. Negeri Tial and Laha are the centers of handline fisheries in Ambon Island. This study was conducted by survey. Primary data collection through empirically constructed questionnaires and secondary data obtained from several related agencies. Samples were taken purposively, so that the number of samples in each Negeri was 20 units. A qualitative method approach is used to describe the technicalities of tuna fisheries production, while for other purposes a quantitative approach is used. The results showed that in increasing production, tuna fishermen in Tial and Laha used relatively the same type of hand line and fishing vessel size, but the use of artificial bait in Laha was more varied. Both research objects gain advantages and are feasible to be developed. Fishing input that is efficient in increasing production is the experience of fishermen and the frequency of fishing. Based on the research results, hand line tuna fisheries in Negeri Tial and Laha can be developed to improve the welfare of business actors.

New Data on the Biology and Fisheries of the Threatened Palinurus elephas (Fabricius, 1787) (Decapoda, Achelata, Palinuridae) from the North-West Aegean Sea, Greece

The European spiny lobster Palinurus elephas is a vulnerable species that inhabits and is harvested in the Mediterranean Sea and the adjacent Atlantic waters. The fisheries associated with the spiny lobster are mainly conducted with tangle nets, trammel nets, pots, and creels. The fishing pressure has greatly reduced their numbers, changing them from a common shallow coastal species to a largely remnant population. The relative research on the species’ biology and fisheries from the eastern Mediterranean Sea is almost absent. The fishery along the Chalkidiki Peninsula, Greece, is multispecies, and fishing is conducted by a small number of artisanal fishermen mainly using trammel nets. The lobster stock—both spiny and clawed lobsters—declined significantly during the late 1980s and early 1990s, later than most cases in the Mediterranean Sea. However, data regarding the nature and status of the fishery associated with the spiny lobster in Greece are lacking. Data regarding the characteristics of the spiny regional fishery were obtained by interviews and questionnaires. Additionally, fishery surveys were conducted during the main lobster fishing season from 1 May 2017 to 31 August 2017. Sixteen species were identified (15 finfish species and one invertebrate species) as targeted. In total, 79 spiny lobsters were sampled in this study; the population’s sex ratio significantly diverts from the theoretical 1:1 (χ2 = 4.57; p < 0.05), and males were dominant. Both male and female individuals demonstrate negative allometric growth profiles. In addition, no significant differences were observed between sexes. In Greece, thus far, the knowledge and information are sporadic, limited, and/or species-specific, most of which regard finfish fisheries. Furthermore, the national legislation is rather complicated—or too generalized—thus creating great uncertainties. The in-depth knowledge and experience of fishermen should be further acknowledged and utilized, and wider collaborations among scientists, practitioners, and policy-makers should be established. The present study poses some thoughts on the effectiveness of the recent EU Landing Obligation and its contribution to the potential restoration of the species.

Factors Influencing The Income Of Fishermen

The purpose of this research was to determine the variability of fishermen's incomes by looking at the effect of fishermen's experience, fishermen's education, and fisherman's working hours on income. The population of this research is fishermen in East Belitung Regency with a sample of 181 people and Central Bangka Regency as many as 57 people. The method is carried out through quantitative analysis using path analysis, with primary data in the form of interviews and questionnaires to fishermen. The results showed that the variables of fishermen's experience and working hours had a significant effect on the variability of fishermen's income, as evidenced by the probability of significance at 0,000 (below 0.05) and F-count, t-count is greater than F-table, t-table. While education is not a factor of variability in fishermen's income because the results of the F-count, t-count is smaller than the F-table, t-table. Future research should measure the variability of fishermen's incomes using variables of the level of fish production, the amount of credit or debit, side income, and poverty of fishermen, using Micmac and Mactor method.

Sosio-Ecological Dynamic of Small Scale Fisheries in Prigi Trenggalek

Small scale fishing is a very important part of the fisheries sector. Not only play an important role in enhancing food security, but also becomes an absorbent for workers without the need for educational. Actors in the small-scale fishery, as defined by Law 45 of 2009, are fishermen who fish their daily needs with the largest size of 5 (five) Gross Register Tonnes (GT) of fishing boats. The fishermen of Prigi are dominated by small fishermen, where the fleet is no larger than 5 GT. The number of small-scale fishing gear in Prigi exceeds 60% of the total gear. The dominance of small-scale fisheries promotes good management with long-term goals, namely the sustainability of fisheries. Today's management of fisheries management has shifted from conventional management to community-based management. In order to support the community-based management of fisheries management, various information about the community, which is the policy objective, is needed. To this end, small-scale fisheries research in Prigi and strategies for the adaptation of the extended fishery fisheries were carried out. The method used is the snowball sampling method and the calculation of the diversity of catching resources. Fishermen who are the subject of the research are small-scale fishermen who operate ships under 5 GT. The gear is stretch fishing, gillnets and tonda fishing rods. There are small fishermen in Prigi who have different types of gear that are used at that time depending on the season of the fish. The selection of fishing gear by fishermen is likely to be caused by different expertise, skills and experience of fishermen in the operation of fishing gears. In addition, the capital held by fishermen to produce fishing gear and the economic level of the fish caught will also likely affect the fishers in choosing the type of fishing gear used each day. The adaptation strategies of fishermen to unpredictable catches are divided into two groups, namely the catch strategy and the search for alternative sources of income.

Comunidades costeras del noroeste mexicano haciendo ciencia

En México la actividad pesquera más significativa es la ribereña o artesanal. La situación actual de la pesca ribereña en México muestra una urgencia por medidas de manejo pesquero participativas. El Programa Marino del Golfo de California (PMGC) creó el Programa de Ciencia Colaborativa (PCC), como mecanismo para integrar el conocimiento y experiencia de pescadores y científicos para entender el estado de los recursos pesqueros comercialmente importantes, implementando técnicas innovadoras que permiten integrar la investigación participativa donde la tecnología y la confianza son componentes clave del proceso. Desde el 2009, las comunidades pesqueras de San Felipe en Baja California, El Golfo de Santa Clara en Sonora, Punta Abreojos, Puerto Adolfo López Mateos, Puerto San Carlos y Puerto Chale en Baja California Sur se han integrado al PCC para comprender el vínculo entre sus pesquerías y los recursos naturales incluyendo el componente espacio – temporal. Hasta ahora contamos con una extensa base de datos para analizar la dinámica pesquera desde una escala regional y por comunidad. El PCC tiene un impacto positivo en el cumplimiento de las metas de conservación, esta metodología tiene un valor incalculable para la investigación y el crecimiento sostenible de las comunidades. La información generada es objetiva y ha sido incorporada en procesos de toma de decisiones, en los cuales las comunidades y administradores de recursos han expuesto su interés en implementar alternativas de manejo que se adecúen a las necesidades de los usuarios

The trajectory of the life of artisan fishermen victims of spinal cord injuries caused by diving: experiences, social representations and stress

Aim: To analyze the social representations, stress levels and experience of fishermen who are victims of spinal cord injury as a result of diving accidents. Method: This is an exploratory and descriptive study that uses quantitative, qualitative and representational data. It was developed in the fishing colonies located on nine beaches in the northern coast of Rio Grande do Norte, Brazil, involving 44 fishermen. Data was gathered from October 2013 to August 2014, and semi-structured interviews, with closed and semi-open questions, were used. Data were analyzed using descriptive and analytical statistics using ALCESTE software in the light of the analysis of social representation theory and content analysis. Results: The participants were male, aged 49.6 years on average, of elementary school level (68.2%), married (77.3%) and suffering from paraplegia sequelae (50%). The analysis of the qualitative data led to the identification of seven categories. Conclusion: The social representations of the cases of spinal cord injury are concerned with the moment of transition between before and after the accident, and they involve the prevention of fishing activity, facing the situation with the remaining potential sequelae, and the consequent impact of stress.

Fishermen's perspectives on climate variability

Understanding fishermen's perspectives and responses relating to climate variability is important for sustainable fisheries management. To this end, a survey of captains of commercial passenger fishing vessels (CPFVs) was conducted in San Diego. The survey demonstrates that fishermen have observed and adapted to changes in the environment and fish populations associated with climate variability. However, only 12.9% of respondents agreed that global climate change is a possibility. In order to explain fishermen's divergent beliefs on climate change, a semiparametric discrete choice model is used to identify the potential determinants. The empirical results highlight the importance of the following factors: fishermen's experience, observations of the phenomena that are associated with climate variability, and an interaction of fishermen's experience and their observations.

Technical Efficiency of the Longline Fishery in Hawaii: An Application of a Stochastic Production Frontier

This paper examines the level and determinants of technical efficiency for a sample of domestic longline fishing vessels operating in Hawaii in 1993. The data on per-trip costs and revenues, fishing targets, vessel ownership, experience and education level of fishermen, vessel size, and vessel age are analyzed using a translog stochastic production frontier, including a model for vessel-specific technical inefficiencies. Output elasticities, marginal productivities of inputs, and returns to scale are also examined. The technical inefficiency effects are found to be highly significant in explaining the levels of and variation in vessel revenues. The mean technical efficiency for the sample vessels is estimated to be 84%. Vessels that target swordfish, and those varying target by season, set, or trip, tend to be less efficient than those vessels targeting tuna and those mixing targets in all trips. Owner-operated vessels seem to be more efficient than those operated by hired captains. The experience of fishermen has a strong positive influence on technical efficiency. Although insignificant, vessel size and fishermen's education level have a positive influence, and vessel age has a negative influence on vessel efficiency.

Environmental Variability and the Stability in the Outcome of the Professional Fishery in Lake Ijssel, the Netherlands

Fishermen experience natural variability through variations in their annual catch per species. In Lake IJssel the catches of pikeperch, Stizostedion lucioperca, in 101 mm gillnets show the largest variability, compared with the variability in the catches of perch, Perca fluviatilis, in these nets and of eel, Anguilla anguilla, in fykenets. Variability in recruitment is the major cause of annual variation in the catch of pikeperch and perch. Year-class strength of pikeperch is highly correlated with summer temperature. Effort limitation provides a marginal gain in stabilising the annual catch in the Lake IJssel pikeperch and perch fishery. In spite of severe over-exploitation, the total outcome of the Lake IJssel fishery has been stable over the last decade, because of the low variability in the catches of eel and because all together four species are exploited.
