Abstract

Governance (policy) that regulates fisheries resources needs to involve industry in the supply chain (market) and small-scale grouper fishermen (community) within a co-management framework so that management is more effective while simultaneously supporting the Fisheries Improvement Project (FIP) which is driven by various parties globally (Conservation Alliance, 2021). This study aims to recommend a small-scale grouper fishery co-management model to be carried out in South Sulawesi Province. This study diagnoses the readiness (enabling condition) and willingness (motivation) of stakeholders so that they can be applied and implemented consistently (implementation). The results of this study indicate that the main approaches and strategies for the co-management model of small-scale grouper fisheries include (a) Optimizing the role of the market that promotes traceability and improving governance through a supply chain approach, (b) Synergy and synchronization of the role of government at all levels through an approach technocratic, (c) Strengthening fishermen and local institutions through a participatory approach, (d) Gathering multi-stakeholder support and collaboration through a collaborative approach. The recommended roadmap for small-scale grouper co-management in South Sulawesi Province includes three main stages, namely: (a) Initiation Stage: Commitment, Support, and Organizing, (b) Acceleration Stage: Joint Committee and Co-management Prototype, and (c) Stage Institutionalization: Scaling up and Organizing Fishermen's Forums.

Abstract

Management of small pelagic fish resources is one of the efforts to prevent a decrease in the carrying capacity of small pelagic fish resources which has continued to experience a decline in production capacity in Buton Regency since the last 5 years since 2016. This study aims to analyze CPUE (Catch per Unit Effort), sustainable potential (MSY) and level of utilization and level of exploitation so that it can become information for managing the utilization of small pelagic fish resources. The research method used analysis of the level of utilization and level of effort based on statistical data on fisheries production for the 2016-2020 period. The results of this study indicate that there is a relationship between CPUE and fishing effort, namely a decrease in CPUE of 0.4092 tons for every increase of effort of 1 effort, optimum catch value (CMSY) of 9447.04 tons per year, and optimum effort value (EMSY) of 152 attempts per year, the utilization rate is still below CMSY with an average of 7557.64 tons and the utilization rate has exceeded EMSY with an average of 178 units per year. The average value of the utilization rate for small pelagic fish in Buton Regency is 94.56%, meaning that it has exceeded the Total Allowed Catch (TAC) but not exceeded the MSY value, while the average effort level is 116.84%. This means that fishermen's catches can still be optimized, but may not exceed MSY, which is 9447.04 tons per year. Trends in the level of utilization and effort level of small pelagic fish resources in the last five years indicate that the utilization rate of small pelagic fish resources has decreased in line with increasing levels of exploitation each year.

Abstract

Pink shrimp (Metapenaeus affinis) or Jinga shrimp is one of the species caught in the waters off Samboja Kuala. This catch is a valuable commodity in the market. The possibility of exploiting shrimp resources will be jeopardized in an effort to conserve, utilize, and catch high intensity shrimp. This study was conducted from September to December 2022 with the aim of determining population dynamics parameters using the frequency method from carapace length data. A mini trawl was used to collect shrimp in the waters of Samboja Kuala, Kutai Kartanegara Regency. Male and female jinga shrimp have a ratio of 1:2,43. Furthermore, for male and female shrimp, the growth rate coefficient (K) was 0,580 and 14,00, respectively, and the approximated natural length (L) was 145.82 and 160.81. Pink shrimp (Metapenaeus affinis) have natural mortality (M) of 1,113/year, mortality due to capture (F) of 0,516, and total mortality (Z) of 1,630, with exploitation value (E) of 0,316, indicating that they are still at the appropriate level. Herefore, female shrimp peaked in August at 14,6% and males peaked in July 31,81%. The Y/R capability was 0,049/year, and Emax calculated the Y/R relationship with the exploitation rate, which was 0,42.

Abstract

Common pleco is a wild fish whose habitat occupies a lot of reservoir areas and public waters in Indonesia. The amount is abundant and not consumed by humans, is a great potential to be used as a source of animal protein in fish feed. The purpose of this study was to evaluate the digestibility of common pleco fish meal in artificial feed for nile tilapia (Oreochromis niloticus.) The study was carried out at the Aquaculture Laboratory Hatchery, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, while the manufacture of common pleco meal, proximate analysis of feed ingredients and the test feed was carried out by the Laboratory of Chemistry and Animal Feed, Faculty of Animal Husbandry, Universitas Padjadjaran. The design used in this study was a Completely Randomized Design (CRD) consisting of 5 (five) treatments and 3 (three) replications. The treatment given was the addition of common pleco flour in artificial feed at 0%, 5%, 10%, 15% and 20%. The parameters observed in this study consisted of digestibility, growth rate, and water quality. The results of the research on some of these parameters indicate that the addition of common pleco meal can still be used in artificial feed up to 10%. The tilapia studied had the highest relative growth with a value of 0.218%. The digestibility level of the studied feed reached a value of 85.256%, and the water quality studied was still within the safe tolerance limits for fish farming. Based on the results of this study, the negative effect on the survival rate of tilapia did not occur until the addition of common pleco flour to artificial feed reached 10%. Thus, the fish meal has the potential as an alternative to fish meal in fish feed formulations.

Abstract

This study aims to compile socio-economic mapping and analyze socio-economic factors that influence tilapia farmer communities. The research was conducted from January 2023 to March 2023 in Lengkong Kulon Village, Sindangwangi District, Majalengka Regency. The method used is the survey method. Sampling using the purposive sampling technique was analyzed with descriptive qualitative. The results of the mapping are grouped into two aspects, namely social conditions and economic conditions. The social condition of fish farmers is that they are of productive age with a low level of education. Livelihoods as fish farmers are part-time. The aquaculture business is mostly done by men as breadwinners, while women play a role in carrying out domestic activities, the role of women in fish farming is only to help provide feed. The social stratification of the fish farmer community is in the lower strata as ordinary people. Farmers generally have a strong kinship based on family ties. The economic conditions of most fish farmers have income that is in the low category, which is less than IDR 5,000,000 per month. Social factors that hinder fish farming in developing their business are lack of counseling, lack of training, and livelihoods as fish farmers are part-time so they are not serious about carrying out the fish farming business. The economic factors that hinder fish farmers are the high prices of feed and seeds.

Abstract

The Makassar Strait waters area is a potential area for the utilization of marine fishery resources in Indonesia especially for large pelagic fisheries because it is one of the migration trajectories of little tuna (Euthynnus sp.). In order to optimally utilize tuna resources, remote sensing technology based on oceanographic satellite imagery can be relied upon to facilitate identification, prediction, and spatial and temporal mapping of potential fishing areas. This study aims to study the phenomenon of oceanography (thermal front) as an indicator of potential for little tuna fishing areas in the Makassar Strait. Primary data was obtained through in-situ data collection (direct observation in the field by following fishing operations using the purse seine, while secondary data consisting of oceanographic data such as sea surface temperature and sea surface chlorophyll-a concentrations sourced from satellite imagery data (Aqua satellite with MODIS sensor). The distribution of the thermal front was analyzed using ArcGIS 10.4 software to determine the relationship between little tuna fishing productivity and the oceanographic phenomenon. Based on the analysis results, total of 61 positions for little tuna fishing using a purse seine, five (5) fishing positions were in the thermal front area, where the catch of little tuna is higher than the average catch outside the area. These results indicate that the thermal front can be used as an indicator of potential for little tuna fishing areas in the Makassar Strait.

Abstract

The Spermonde Archipelago is divided into four zones, the division of zones is based on the distribution of coral reefs, distance from the mainland, and water depth, but this condition tends to change as a result of high anthropogenic activity in the Spermonde Islands. Based on this, it is very necessary to re-zoning the Spermonde Archipelago Waters based on the condition of nutrient distribution. The research method uses the integration of remote sensing data analysis, field surveys, and secondary data which are then analyzed using the Boleean method for re-zoning. The results showed that the nutrient, in this case, chlorophyll-a, was concentrated in the deep zone (near the mainland) and the concentration was higher during the rainy season, this condition affected the coral reef cover in the Spermonde Islands. Based on these conditions, the Spermonde Islands waters are divided into three zones, namely the inner zone with high nutrient conditions with a benthic cover dominated by fleshy macroalgae, the middle zone with low nutrient conditions with crustose coralline dominance, and the outer zone with low nutrient conditions with algal turf dominance turf alga/corals.
