Development Potential of Fisheries as a Maritime Activity in Supporting Area Planning

This paper aimed to identify and discuss the gains on the development of fishery, maritime tourism and community engagement towards the regional planning of Belakang Padang District in Indonesia. Based on both exploratory and explanatory qualitative and quantitative data collected for the study, the study establishes and examines the economic, cultural, and environment opportunities and barriers to region development in the district. The studies show that fisheries are the largest and most important economy sector that influences the planning of regions; at the same time, the challenges are observed in terms of outdated technique and restricted access to markets. Maritime tourism has a lot of prospects and long-term influences for countries but it is restricted by the lack of sufficient infrastructure and capital. The study also highlights a major research agenda concerning the lack of citizenship in planning where most of the local actors are rarely involved in planning processes. Environmental sustainability as an additional challenge was discovered with pollution together with the inadequate disposal of wastes contributing to the harm of the district’s development. Therefore, the study recommends an integrated regional development plan, focusing on the modernization of fisheries, tourism development, participation of community and conservation of the environment as key factors for sustainable development of Belakang Padang. Hence the research is useful in the existing literature on sustainable coastal development and charles district future planning activities.

Can pots be an alternative fishing gear to gillnets? A Mediterranean case study

Small-scale coastal fisheries in the Mediterranean often employ gillnets, a widely used gear worldwide. The disadvantages of gillnets in this fishery include high bycatch levels of unwanted species and consequent discards. Moreover, spatial conflict with other gears and dolphin depredation often results in considerable economic loss. Alternative fishing methods are being tested. This study investigated whether, in small-scale fisheries in the Adriatic Sea, pots can ensure sustainable harvest of mantis shrimp (Squilla mantis), a major target demersal species in terms of landings, and possibly replace traditional gillnets. We adopted a multidisciplinary approach to investigate the catch efficiency, biological impact, and socio-economic effects of the two fishing methods. We found different species compositions in gillnet and pot catches. Gillnets yielded a greater number of discarded species of no commercial value, whereas pots caught a greater amount of mantis shrimp. Finally, a profit analysis indicated that pot fishery has the potential to increase profits for the commercial fishing industry. This study suggests that pots provide a more sustainable fishing method, both in terms of revenue and environmental impact.

Indonesia, as an archipelagic country with substantial fishery potential, faces challenges related to low fish consumption levels among its population. Muntai Barat Village in Bantan District, Bengkalis Regency, Riau Province, possesses significant fishery resources that remain underutilized. In response, a community service initiative comprising Fish Consumption Promotion Counseling and Fishery Product Demonstration was conducted to enhance public understanding of the importance of fish consumption and its health benefits, and to stimulate entrepreneurship and the creative economy by leveraging local fishery potential. The methods employed included interactive counseling and demonstrations of processed fish products, specifically mackerel and shrimp dumplings. Participants included 15 members of the village's women's group (PKK). The results indicated a significant increase in participants' knowledge of the nutritional content and benefits of fish, with a 45.34% improvement in post-test scores compared to pre-test results. All participants (100%) successfully created fish dumpling products, reflecting improved skills in processing fish into economically valuable products. Support from the village government in the form of business fund access for participants is expected to encourage the establishment of 3-5 fishery-based business units within six months. In conclusion, this activity effectively increased community awareness and skills in utilizing local fishery resources, potentially fostering the growth of the creative economy in the village.

Sustainable Development Strategy Based on Value-Addedin the Fisheries Sector: Study on the Kangean Islands, Sumenep Regency, Indonesia

Objective: Kangean Islands is a group of small islands in Sumenep Regency, East Java Province, Indonesia, which is administratively divided into three sub-districts, namely Arjasa District, Kangayan District, and Sapeken District. This archipelago has very large fisheries potential as seen from its contribution to the Gross Regional Domestic Product (GRDP) of Sumenep Regency, but the utilization of the fisheries sector in this archipelago is still carried out traditionally and tends to be exploitative. This study aims to see the level of sustainability of fisheries sector management and recommend fisheries resource management strategies, in order to increase the economic added value of the fisheries sector and maintain the sustainability of fish resources and the environment in the archipelago. Method: The analytical method used to analyze the degree of sustainability in fisheries resource management in the Kangean Islands is Rapid Appraissal for Fisheries (RAPFISH) with the Multi-Dimensional Scaling (MDS) ordination technique. While the analytical tool used to compile a hierarchy of fisheries sector development strategies to increase economic added value is the Analytical Hierarchy Process (AHP). Results and Discussion: The results of the sustainability analysis in the management of the fisheries sector found that, of the five aspects identified, the results showed that the financial aspect and infrastructure aspect had the category of "Sustainable Sustainability", with values of each aspect of 63.113 and 53.885. While the other three aspects, namely: Human Resources (HR) Aspect, Natural Resources Aspect, and Social Aspect are included in the category of "Less Sustainable". Meanwhile, based on the results of the analysis of the hierarchy of fisheries sector development policies, it shows that the most priority policy to be carried out in the development of a sustainable fisheries sector is the "identification of investment potential and opportunities" program with a priority value of 46%. Furthermore, the strategy that must be chosen is to map the potential of the fisheries sector with a limiting value of 21%. With a Rater Agreement value strength of 0.472727 or 47%, it means that the informants agree in providing an assessment on the paired comparison questionnaire, in determining problems and strategies in the development of the fisheries sector in the archipelago.

Social media influence on the promotion of sustainable fisheries management: Insight from Indonesian blue swimming crab

Abstract Blue swimming crab is one of potential fisheries commodities in Indonesia that has been mainly exported to America. Crab industry contributed to national economy due to high export volume and value. The use of social media has surged due to digitalization, becoming a crucial marketing strategy for maximizing business profits. The role of social media in non-profit organizations for fisheries sustainability campaigns remains unexplored. Therefore, this study aimed to analyze to the role of social media in promoting sustainable blue swimming crab fisheries programs in Indonesia. Data was collected for 14 days from 31 social media users on various platforms, such as Instagram, Facebook, LinkedIn, and YouTube. SmartPLS 3.2.9 was applied to analyze the effect of recall, recognition, alternative, and recalling on blue swimming crabs fishery programs on interaction and effectiveness consumer brand engagement (CBE). Results showed that the most recognized fisheries sustainability programs for blue swimming crabs were crab apartment and GTK-5 Minutes. Meanwhile, the crab enlargement program and APRI Youth Innovation were known through moment-open recruitment. Knowing and following APRI’s social media has significant effect on CBE’s interaction and effectiveness. Social media could also be used as a marketing strategy to promote sustainable fisheries management programs The research reveals the significance of social media in fostering consumer engagement and promoting sustainable practices in fisheries management programs by non-profit organization through effective marketing strategies.

Indonesian And Malaysia Sea Defense Strategies In Responding The South China Sea’s Threats

The South China Sea is a source of conflict between China and Southeast Asian countries such as Indonesia and Malaysia because China claims the nine-dash lines that pass through the Indonesian Exclusive Economic Zone and the Malaysian territory. This area has high fishery potential and is the main route for global trade, so the maritime defense strategies of the countries concerned are very crucial. This research method uses qualitative data sources using literature studies. The results of the analysis and discussion show that there are differences between Indonesia's and Malaysia's maritime defense strategies, which are influenced by factors such as the fact that Malaysia is one of the ASEAN countries that claims the South China Sea area. However, Indonesia and Malaysia have similarities by using soft power diplomacy and track-3 multi-track diplomacy in dealing with these threats, one of which is due to the economic cooperation of the both countries with China.

Analysis of recommendations for developing sustainable fishing areas based on geographic information systems: the integrated Center of Marine and Fisheries (SKPT) Mimika case study

Abstract The Integrated Center of Marine and Fisheries (SKPT) is one of the Indonesian government’s steps in developing better management of the fisheries sector. SKPT Mimika has “The golden fishing ground” waters with a capture fisheries potential of 2.64 million tons per year; Arafura waters are one of the most fertile waters in Indonesia. With this potential and the concept of water development, namely the blue economy, where the economy with the axis of the sea must be sustainable, has a high urgency to ensure that there is no excessive exploitation of marine resources. The development of a sustainable blue economy involves many parties, but we consider that the closest community is the answer to the success of this development. Creating the potential fishing zone (PFZ) from Aqua MODIS image data and SWOT Analysis to formulate sustainable recommendations can help the community and stakeholders. Some of the outcomes of our recommendations are 1) Empower and implement an adaptive management approach that considers the needs and situations of each member of society, community, and region; 2) Increase the resilience of fisheries and aquaculture systems through implementing sustainable practices, diversifying fisheries commodities, and increasing access to markets. 3) Increase the ability of fisheries and aquaculture stakeholders to adapt to the impacts of climate change through training, education and awareness-raising activities; 4) Integrate the fisheries and aquaculture sectors into national policies and strategies for climate change; and 5) Management of intentional fishing and dumping.

Mapping the Suitability of Milkfish Ponds in Sidoarjo District Using Geographic Information Systems (GIS)

Milkfish is one of the potential fishery products in Sidoarjo Regency. Sidoarjo District, one of the subdistricts in Sidoarjo Regency, has significant potential for milkfish development due to its 3271.96 ha of land area. Pond suitability analysis is a crucial aspect of supporting the success of milkfish cultivation. Land suitability can be analyzed using Geographic Information Systems (GIS). This research involved two phases: data collection and analysis. The data parameters collected are temperature, pH, DO, phosphate, and salinity. The data analysis employed overlay and scoring methods. The final scoring results were categorized into four classes, including classes S1 (Very Suitable), S2 (Quite Suitable), S3 (Conditionally Suitable), and N (Not Appropriate). Based on analysis of Landsat image data, the pond area in Sidoarjo District reached 2991.03 Ha. The final scoring results showed that the pond area in the S1 category was 1,816.53 Ha (60.73%), then the S2 category was 1174.50 ha (39.29%). Referring to the calculation of the percentage of pond suitability, most of the ponds in Sidoarjo District are very suitable for cultivating milkfish.

Estimation of Mariculture Carbon Sinks in China and Its Influencing Factors

The scientific assessment of mariculture carbon sinks is crucial to recognize its potential as a significant component of marine blue carbon in global climate change mitigation. Therefore, the objective of the research was to estimate the seaweed and shellfish mariculture carbon sink of different varieties in various sea areas. The paper emphasized the distinction between short-term carbon sequestration in seaweed and shellfish that can be removed and long-term carbon sequestration that is deposited. Methodologically, the evaluation was based on the carbon sequestration mechanism and systematic pathways in shellfish and seaweeds. Additionally, the carbon sequestration of shellfish and seaweed aquaculture over the last decade was evaluated by the carbon sink assessment model, and the reasons for the differences in the carbon sink capacity of mariculture in China’s coastal provinces were discussed by using the LMDI decomposition model. The results indicated the carbon sequestration of offshore seaweeds and shellfish mariculture in China was huge. From 2010 to 2020, offshore seaweed aquaculture in China amounted to 7.959 Mt C/a, while shellfish aquaculture contributed 33.542 Mt C/a to the carbon sinks. Sedimentary carbon sequestration by shellfish accounted for 51% of the total carbon sequestration in mariculture involving shellfish and seaweeds. Especially noteworthy is the sedimentary carbon sequestration by shellfish, which is an indispensable and crucial component of mariculture carbon sequestration estimation. It is concluded that improvements in farming efficiency exerted the greatest influence on the variations of the mariculture carbon sink, while adjustments in farming structure had a relatively minor impact in the case of little change in aquaculture yield. Enhancing farming efficiency emerges as a practical approach to bolstering the carbon sink potential of marine aquaculture fisheries in the future.

Selectivity in snow crab (Chionoecetes opilio) pot fishery: Effect of escape gap shape and size for conservation of fishery resources

Conical pots are commonly used fishing gear for capturing snow crab (Chionoecetes opilio). In these fisheries, optimal snow crab size selection is important for reducing unintended mortality of undersized individuals aiming at conserving fisheries resources and reducing sorting time onboard fishing vessels. Size selection in snow crab pot fisheries commonly takes place through pot netting meshes during deployment. The diamond mesh netting has varying opening angles affecting retention of snow crab of different sizes, and often large proportions of catches consist of undersized crab challenging natural resource conservation. Some commercial snow crab fisheries use rigid escape gaps in addition to mesh selection to improve size selectivity. In this study, we predict the size selection potential of escape gaps with different shape and size and investigated whether such additional size selection mechanism can have a potential to improve selectivity compared to mesh selection. Results showed that circular escape gaps have potential to provide sharper size selection compared to netting meshes and thus could be used to limit the capture of undersized snow crab which is relevant for management and conservation of snow crab resources. However, a similar positive effect cannot be obtained to the same extent with elliptical and rectangular escape gaps.

POTENTIAL AND UTILIZATION LEVEL OF KRAI TUNA (Auxis thazard) LANDED AT SIBOLGA ARCHIPELAGO FISHING PORT NORTH SUMATERA PROVINCE

Krai tuna (Auxis thazard) is the most dominant catch in Sibolga Archipelago Fishing Port and has economic value, so the community widely consumes it. The magnitude of the potential of fisheries in Sibolga makes it important to analyze the stock of krai for the development and processing of the capture fisheries sector. The research method used is the survey method, the data needed is secondary data in the form of catch data and fishing effort for seven years (2016-2022), the data analysis used is the surplus production method with the Schaefer and Fox model approach, From the results of the study, it was concluded that the sustainable potential of krai using the production surplus approach method is more suitable using the Schaefer approach model because it has a low JTB of 1508 tons with a utilization rate status of 98.94% and is already in a fully-exploited condition or has reached the saturation point (catch-intensive). Utilization is almost near saturation point, so it is necessary to reduce fishing effort so that the catch remains and stock availability is maintained

Identification and Modeling of SI-LAUT: Information System for Indonesian Maritime Resources Using Penta-Helix Model

Indonesia, as a country predominantly surrounded by the sea, holds significant potential in marine resources, fisheries, and other maritime fields. However, there is still a lack of awareness and understanding among the Indonesian population regarding these maritime aspects. Currently, there are various media and information sources related to this topic, ranging from websites and applications to supporting information systems. Nevertheless, users often struggle to find and comprehend this information easily and comprehensively. Existing information systems tend to be fragmented or operate independently, leaving many laypeople unable to fully optimize the existing potential. To address this, researchers aim to identify and model a comprehensive and integrated information system focused on marine and other maritime resources, known as SI-LAUT The research method employed in this study consists of literature review, stakeholder identification based on the Penta-Helix model, analysis of the existing system, and gap analysis in comparison to previous research that focused on the implementation of other maritime and marine information systems. The results of this research consists of a recommendation for an information system development model that can assist various stakeholders based on the Penta-Helix Model. These stakeholders include government bodies, entrepreneurs, academics, as well as the general public or other communities. The goal is to optimize the management and utilization of Indonesia’s marine resources, ultimately positioning it as a global maritime powerhouse.

Selectivity of crab pots with escape vents and the optimal vent height for reducing the catch of sublegal swimming crab in the East China Sea pot fishery

Catching and subsequent discarding of sublegal-sized swimming crab Portunus trituberculatus in the pot fishery may result in increased unaccounted fishing mortality and contribute to overexploitation of the crab stocks in the East China Sea. Developing technical measures and implementing related regulations to improve the size selection of pots to reduce the catch of sublegal crab has become urgent. In this study, we evaluated the size selectivity of pots with rectangular escape vents of different opening heights (25 mm, 28 mm, 30 mm and 33 mm) through comparative fishing experiments and by employing the SELECT model. The results show that the installation of escape vents significantly reduced the catch per pot (in numbers) of total and sublegal swimming crabs, and significantly increased the proportion of legal-sized crabs for most vented pots except the 25 mm vent height. A significant positive linear relationship was found between escape vent height and the 50% retention carapace width, selection range and fishing power. Increasing the height of the escape vent had substantial effect on the exploitation pattern for swimming crab and the pot with a 28 mm height escape vent seemed to be the optimal design, releasing 67.4% of sublegal-sized crab and maintaining 94.8% of legal-sized crabs. Results showing that a pot with an escape vent that significantly reduces sublegal crab catch, while maintaining catch efficiency for legal-sized crabs, is positive for the fishery and supports the implementation of escape vents in the East China crab pot fishery.

Prospects for fisheries use of lake Sobache (Pionerskoe) in the Republic of Khakassia

We assess Sobache (Pionerskoe) lake located in The Republic of Khakassia for aquaculture using. The lake is drainless, the water-surface area is about 1.5 km2. The prevailing depths range from 2 to 4 m. We provide data on the hydrological regime of the lake (temperature, dissolved oxygen level, chemical water composition). 3 species of rotifers, 10 species of cladoceran and 3 species of copepods were found in the zooplankton. The dominant complex consists of the rotifer Asplanhna priodonta, Bosmina longirostris and Ceriodaphnia quadrangula. The zoobenthos community includes 13 groups of organisms, where chironomids predominate in abundance, and gastropods and bivalves predominate in biomass. The ichthyofauna of the lake consists of perch and pike, perch predominates in abundance. Four species of parasites were found, including trematodes and myxporidia. The infection of fish with trematode metacercariae indicates the presence of intermediate hosts in the zoobenthos community of the lake. The detected species of parasites do not pose a danger to human health. The natural fish productivity is estimated at 48.2 kg/ha. We recommended to use the lake for commercial cultivation of fish in polyculture way. We proposed two schemes of fishery exploitation of the lake on the principle of pasturable fish culture: annual cultivation of fish in polyculture (carp, trout, herbivorous fish species) and joint cultivation of fish in polyculture (carp and white amur) by continuous intensive technology (three-year turnover) with carp feeding. The expected yield of fish products varies from 460.0 to 400.0 kg/ha, depending on the chosen technology. These recommendations can contribute to the effective use of the fisheries potential of Sobache (Pionerskoe) lake to provide the region with fresh fish products and create jobs for the local population.
