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.","PeriodicalId":278380,"journal":{"name":"Torani Journal of Fisheries and Marine Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130843816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":278380,"journal":{"name":"Torani Journal of Fisheries and Marine Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129896573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":278380,"journal":{"name":"Torani Journal of Fisheries and Marine Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131178603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":278380,"journal":{"name":"Torani Journal of Fisheries and Marine Science","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122166300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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%.

This research was conducted in October – December 2021. Milkfish (Chanos-chanos) aquaculture business in Bonto Manai Village was chosen as the case, because the aquaculture system managed by the community is dominated the traditional aquaculture system. The purpose of this research is to analyze the knowledge of traditional aquaculture as a technical practice in managing aquaculture businesses, as well as to analyze the work relations of traditional aquaculture businesses which are internalized in the local culture of the community. The methodology used is a case research method with a descriptive qualitative data analysis approach described in the life history of the informants. The results showed that traditional farmers in milkfish (Chanos-chanos) aquaculture in Bonto Manai Village have acquired knowledge gained through experience passed down from generation to generation, starting from the construction and management of pond subgrade, seed stocking, rearing, harvest and post-harvest. Accompanied by rituals based on belief as a traditional value. The managerial pattern and work relations in the management of traditional pond business have three types of management, namely; aquaculture business which is self managed by the owner of the aquaculture land with involving two to three workers, aquaculture business which is managed based on a leasing system, and aquaculture business which is managed by a rapture system.\u0000Keywords: Managerial Pattern, Work Relations, Traditional Pond, Milkfish\u0000 ","PeriodicalId":278380,"journal":{"name":"Torani Journal of Fisheries and Marine Science","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115562786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
