Abstract

The belat is a passive fishing gear that belongs to a group of traps operated in areas around the coast. In its operation, the belat not only produces the main catch but also gets bycatch. This study aims to identify the main catch and by catch. The research method used is the survey method by making direct observations of the belat catch and then the catch is identified as the type of fish, the number of individuals, and the weight of the fish. The results of descriptive analysis showed that the main catches were two types of shrimp, namely white shrimp (Penaeus indicus) and striped shrimp (Penaeus monodon) with a weight of 30400 g. The main catches were white shrimp (Penaeus indicus) and striped shrimp (Penaeus monodon). The by-catches were small fish and young fish, the by-catches consisted of 6 species with a total weight of 29300 g

Abstract

Gillnet fishing gear is an environmentally friendly fishing gear but in 2018-2020 the catch was reduced. The purpose of this study was to determine the sustainability status of gillnet fisheries based on ecological, social, and economic aspects at the Riau Province Fisheries Port Technical Unit. Data analysis in this study used Rapfish (Rapid Appraisal for Fisheries) technique. The rapfish technique is a multidisciplinary ordination technique used to evaluate/determine/compare the status of fisheries in terms of their sustainability. This study shows that in general, the sustainability index of gillnet fisheries in the Riau Province Fisheries Port Technical Unit is between the index values of 25.01-50 which is classified as less sustainable. Monte Carlo simulation results show that the distribution of sustainability index plots is at a distance that is not far and coincides with the position of the sustainability index ordination, supporting the accuracy of determining the ordination of the sustainability status examined. Sensitivity analysis showed that the attributes of changes in fish weight in the last 5 years, family participation in the utilization of fishery resources, and alternative employment and income are attributes that greatly affect the sustainability of gillnet fisheries in the Riau Province Fisheries Port Technical Unit

Abstract

EAFM or Ecosystem Approach for Fisheries Management is a concept of how to balance socio-economic goals in fisheries management while still considering knowledge, information and uncertainty about biotic, abiotic and human interactions in aquatic ecosystems through a comprehensive and sustainable integrated fisheries management. The fishery potential is quite large in Bungus waters and the continuous fishing activities carried out by boat lift fishermen lead to overfishing; therefore fisheries management is very necessary to realize sustainable fisheries, especially for fishery commodities. The purpose of this study was to determine the status of the management of the bagan boat fishery in Bungus pps. This research was conducted in February 2022 at the Samudra Bungus Fishing Port, West Sumatra. The method used in this study uses the method issued by the National Working Group EAFM.DIT SDI KKP; the data taken are primary data and secondary data. Analysis of the data used using an ordinal-based likert scoring with a scoring assessment of 1,2,3. The greater the value, the better the EAFM that has been run. The results of the study show that the management of capture fisheries in the fishing technique domain at PPS Bungus is still lacking in implementing EAFM with a composite value of 18.8

Abstract

The uncontrolled fishing of skipjack tuna (Katsuwonus pelamis) without recruitment efforts has led to stock degradation and unstable abundance due to excessive pressure. This study aims to estimate the sustainable potential of skipjack tuna by calculating Catch per Unit Effort (CPUE), assessing Maximum Sustainable Yield (MSY), and determining Total Allowable Catch (TAC). The research was conducted at PPN Sibolga and utilized survey-based data collection and surplus production analysis using the Schaefer model. The findings indicate that standardized CPUE in 2018 was 0.639 tons/trip, increased to 0.764 tons/trip in 2019, dropped to 0.527 tons/trip in 2020 and 0.506 tons/trip in 2021, and returned to 0.639 tons/trip in 2022. Purse seines were identified as the primary fishing gear. The Schaefer model estimated CMSY at 8,699.7 tons, classifying the fishery as fully exploited. FMSY was calculated at 5,447 trips, with annual efforts consistently exceeding this threshold, indicating overfishing. The TAC was set at 6,959.7 tons. Management strategies should regulate fishing efforts, enforce gear specifications, and implement science-based fisheries policies to prevent further degradation. Aligning fishing activities with sustainable thresholds will support skipjack tuna stocks' recovery and long-term productivity. These findings underline the importance of adaptive management and collaboration to sustain marine ecosystems and protect livelihoods

Abstract

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.

Abstract

Dumai City relies entirely on marine waters for its fisheries production, with gillnets being a predominant fishing gear among local fishermen. Gillnets, characterized by their rectangular shape with varying mesh sizes, utilize floats and weights. This study aimed to identify the factors influencing gillnet catches in Dumai City. Results from simultaneous testing revealed that all production factors significantly impact catch quantities. Through multiple linear regression analysis, it was determined which factors exerted positive and negative effects. The regression equation, Y = 0.108 – 0.183 X1 – 0.411 X2 – 0.345 X3 + 0.173 X4 + 0.116 X5 + 0.451 X6 + 0.181 X7 – 0.106 X8 + 0.223 X9, elucidated these relationships. The cumulative effect of production factors on catches amounted to 64.20%. This study provides valuable insights into optimizing gillnet fishing practices in Dumai City's marine environment.

Abstract

Sondong fishing gear is one of the dominant fishing gear used by fishermen in the UPT Fisheries port of Riau Province Dumai City, which, when operated, can scrape to the bottom of the waters. The specifications of sondong fishing gear affect the catch. This study aimed to determine the composition of catches based on type, length, and weight and explain the level of environmental friendliness of sondong fishing gear that refers to the FAO 1995 CCRF criteria and Taeran 2014 subcriteria. The method used in this research is a survey method, which is conducted by conducting interviews and collecting data directly in the field, then analyzing it using descriptive statistics. The results showed that the composition of the main catch was white shrimp (Penaeus merguiensis), red prawn (P.monodon), and kelong shrimp (P. indicus). At the same time, the bycatch was white pomfret (Pampus argenteus), gulamah (Pseudocienna amovensis), gangetic anchovy (Thryssa mystax), malung (Muraenesox cinereus), stingray (Dasyatis sp), and crab (Portunus pelagicus). The environmentally friendly level of sondong fishing gear, with a value of 16.43 from the interviews with 23 respondents using 8 criteria, states that sondong fishing gear is a category of fishing gear that is not environmentally friendly.
