Skipjack tuna (Katsuwonus pelamis) is one of high economic valued pelagic fish on the south coast of Malang waters. This fish is usually caught by purse seine. This study was conducted at Sendang Biru Coastal Fishing Port Malang Regency from February to May 2021, aiming to find out the utilization rate and bioeconomic conditions of the skipjack tuna fishery. The study used descriptive methods. Statistical data on catches from 2011 to 2020 were used to apply bioeconomic analysis to calculate the maximum sustainable yield (MSY), maximum economic yield (MEY), total allowable catch (TAC), and free access equilibrium (FAE). Results showed that values of catch and effort at MSY level were 1,800 tons and 3,191 trips respectively with a value of TAC as much as 1,440 tons. While values of catch and effort at MEY reached 1,774 tons and 2,814 trips respectively with the highest profit obtained as much as IDR 34.12 billion. In addition, catch and effort at FAE level took place at 751 tons and 5,627 trips respectively. The utilization rate of skipjack tuna (K. pelamis) was 123%. In conclusion, the fish is in over-exploited condition hence the amount of effort must be decreased to maintain resources sustainability.

Snappers (Lutjanus spp.) are the most common reef fish caught in Taka Bonerate National Park due to its high economic value and primarily targeted species. Without proper management measures, intensive fishing activities might result in unsustainable fish stocks. Therefore, in order to maintain sustainable utilization, it is important to understand the stock status of snapper fisheries. This study aimed to analyze the snappers' stock status in Taka Bonerate National Park's waters. Data were collected from January to December 2022 at three small-scale fisheries landing sites. The results showed that snappers are classified as slow-growing species with growth rates for species L. bohar, L. quinquelineatus, L. gibbus respectively 0,12, 0,39, and 0,35 per year to reach their respective asymptotic lengths of 83,41 cm, 29,5 cm, and 46,80 cm. The stock status of L. gibbus and L. bohar were indicated at overfished status where the exploitation rate (E) was > 0.5 and the SPR was < 0.3, hence a proper management measures is required. Furthermore, the species of L. quinquelineatus has a value of E is 0.5 and SPR is at 0.3, indicating that the utilization level of this species was at an optimal level. Keywords: Snapper, Taka Bonerate, Fisheries Management.

Longtail tuna (Thunnus tonggol) is a pelagic fish which is generally found in tropical waters. Research on fishery resource sustainability by applying bioeconomic and length weight assessments is necessary to be done in order to determine status of longtail tuna. This research was conducted in south part of Java Sea namely Indramayu waters West Java from January 2020 to April 2020 which aims to estimate utilization status of longtail tuna (T. tonggol) namely exploitation rate, Maximum Sustainable Yield (MSY), Total Allowable Catch (TAC), Maximum Economic Yield (MEY), and Open Access (OA), and to determine length and weight relationship. The research used quantitative descriptive method based on catch and effort data from 2010 to 2019 as well as length weight primary data as much as 987 fish. Result showed that catch and effort at MSY level was 8,453 tons/year and 2,974 trips/year respectively with value of TAC as much as 6,762 ton/year. While the estimated values of catch and effort at MEY level was 8,168 tons/year and 2,427 trips/year with optimum profit as much as 88.98 billion Indonesia dollar rupiah (IDR). Another analysis indicated that OA level was achieved when effort reached at 4,855 trips/year and whilst exploitation rate was 93%. Meanwhile length weight relationship analysis showed that fish had a balance length weight growth which b value = 3.039 with equation W = 0.0147L3.0393. In conclusion, the fish has an isometric length weight relationship and the utilization status of fish is in fully exploited condition hence additional fishing effort must be prohibited in order to maintain stock sustainability.
