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

On Rangsang Island, many still work as fishermen or depend on the sea, especially in the southern part of Rangsang Island. Fishermen in the south part of Rangsang Island still use a lot of traditional fishing gear, such as the grinder. The polluted waters on Rangsang Island and destructive technology will impact the fishermen's fishing economy. This study aims to determine and assess the sustainability of fishing gear in terms of ecological, economic, and technological aspects in the southern part of Rangsang Island using the rapfish technique. The method used was a survey method, and the sampling used a purposive sampling technique. The analysis of the rapfish technique found that sustainability in the ecological dimension was 33.53% or less sustainable. In the economic dimension, it was 36.01% or less sustainable. In comparison, it was 76.71% sustainable in the technological dimension.

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.

Abstract

This research was carried out in November 2022 in Merbau District, Meranti Islands Regency, Riau Province, to determine the sustainability status of the belat fishing gear based on ecological, social and technological aspects. The method used in this research is a survey method, while purposive sampling is used to determine respondents. Data collection was carried out through observation, interviews and documentation directly with two academics from the UNRI Faculty of Fisheries and Marine, two people from the Meranti Regency Fisheries Service, four capture fisheries entrepreneurs (traders and collectors), two fishermen group leaders, and ten fishermen. The research results show a decrease in the number of belat fishing gear every year; in 2020, the number of belat fishing gear was 65 units, and in 2022, the number of belat fishing gear was nine units. Belat fishing gear is not selective, as seen from the leverage analysis that has been carried out with a sensitivity attribute value of 40.53. Belat can catch small fish that are not yet suitable for catching. The sustainability status of belat fishing gear is seen through the attribute values ​​of three dimensions. The sustainability index value for the ecological dimension of the belat fishing gear is 51.11, meaning it is pretty sustainable. The sustainability index value of the technological dimension in fishing using belat fishing gear is 40.53, which is classified as less sustainable. The index value of the social dimension in fishing using the belat fishing gear is 59.99, meaning it is in the reasonably sustainable category.

Abstract

The skipjack (Katsuwonus pelamis) in Bungus Ocean Fishing Port has been evaluated for its sustainable potential using the surplus production approach method. The findings indicate a strong alignment with the Fox approach model. The estimated sustainable potential for skipjack is 471 tonnes per year, with an ideal effort of 45 trips annually. The analysis indicates a moderate utilization status, with an average skipjack utilization rate of 62.76%. It is evident that around 37.24% of its maximum sustainable potential, equivalent to 154.74 tonnes per year, is still unexplored. In addition, the catch rate of skipjack is relatively high at 96.14%, indicating that there is still some untapped potential, with 3.86% of the optimal fishing effort or two trips per year remaining unused. As a result, it is recommended that a total allowable catch of 341 tons be set in order to ensure the long-term sustainability of skipjack harvesting in the area.
