Abstract

Kutaraja Ocean Fishing Port (PPS) is a fishing port that has various catch characteristics; one of the most dominant catches is skipjack tuna. The purpose of this study was to analyze the skipjack tuna catches per unit fishing effort (CPUE) and to estimate the skipjack tuna fishing season index at the Ocean Fishery Port of Kutaraja. This research was conducted in October 2021 at the Kutaraja Ocean Fishing Port using the survey method. The results of the study showed that skipjack tuna catches at the Samudera Kutaraja Fishing Port in 2016-2020 experienced quite significant fluctuations. In addition, the fishing effort is quite high so the catch of skipjack per fishing effort (CPUE) for the 2016-2020 periods has decreased. The highest CPUE value was in September 2018, namely 7.163 kg/unit, and the lowest was in January 2016, namely 483 kg/unit. In this study, it can be assumed that the peak season for skipjack tuna occurs in May, July, August, September, and October. The moderate season for skipjack tuna occurs in January, February, March, June, November, and December

Abstract

The main factor for the success of bottom longline fishing depends on the type of bait, both natural bait and artificial bait. The bait serves as an attractant for the target fish so that it is attracted to prey on it. In this study, the bait used was a machete, puput, and layur fish. The purpose of this study was to determine the amount, weight and type of catch based on the appropriate type of bait so that it can be a reference for fishermen for optimal use of bait in the operation of longline fishing gear. This research was conducted in February 2022, located in the waters of Bantan Sari Village, Bantan District, Bengkalis Regency. The method used is the experimental fishing method, by operating the fishing gear directly and analyzing using the analysis of variance and the Least Significant Difference test. Based on the research, the catches obtained were debuk fish, gelama, stingrays, and puffer, with the highest catches in terms of weight, namely stingrays as much as 61800 g.

Abstract

Fish resources have limits; therefore, it is necessary to carry out appropriate management so that resource utilization is sufficient for a long time. Areas used as fishing businesses need to know how the level of utilization. For this reason, clear information is needed on the potential and level of utilization of marine fisheries resources to support the management policy of tuna resources for optimal management and utilization and to prevent the reduction of fish stocks in the future. This research was conducted for three weeks in July 2023 at Bungus Ocean Fishing Port (PPS), Padang City, West Sumatra Province. The method used in this research is a survey method or direct review of the field. The maximum sustainable potential value was obtained at 572.36 tons with an optimum utilization effort value of 330 trips. The allowable catch of longtail tuna is 457.89 tons, with an average utilization rate of 97.41%. Based on the average value of the utilization rate obtained from 2018 to 2019, the number of allowable catches, and the MSY value, it is concluded that the longtail tuna caught by bagan boats and Tonda fishing rods at PPS Bungus has experienced overfishing. There is a need for more action and monitoring of the amount of catch obtained each year, as well as limiting the amount of catch allowed for each fisherman so that the utilization rate of longtail tuna can return to optimal catch and prevent overfishing and maintain fish stocks for the future.

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.
