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

This study aims to analyze the level of selectivity of wire trap fishing gear against limbat fish (Clarias nieuhofii) in the swamp waters of Tebo Regency, Jambi Province. Data collection was carried out by catching trials using 3 units of wire traps with 30 replications, in June-August 2020. The research data were analyzed descriptively using the logistical selectivity model of the maximum likelihood method equation in the solver program from microsoft excel. The results showed that the wire traps were not selective for size but were selective for the limbat fish species (C.nieuhofii). The selectivity curve based on the logistical function shows that the probability of being caught by fish are at 22-48 mm body height, while the size of the fish that can escape has a maximum height of 34 mm or a length of 182 mm.

Abstract

Lobster pasir (Panulirus homarus) merupakan salah satu komoditas yang memiliki banyak peminat sehingga memiliki kecenderungan mendapat tekanan penangkapan yang besar. Akibatnya, terjadi penurunan jumlah produksi dan ukuran tangkap. Hal ini juga diduga terjadi pada lobster pasir yang terdapat di perairan Bengkulu sehingga perlu dilakukan kajian mengenai biologinya. Tujuan dari penelitian ini adalah menganalisis hubungan panjang berat dan mortalitas lobster pasir yang ditemukan di perairan Kota Bengkulu. Penelitian dilakukan terhadap 382 ekor lobster yang tertangkap dengan menggunakan jaring lobster. Hasil analisis menunjukkan bahwa ukuran rata-rata lobster yang tertangkap adalah 50-86 mm dengan lebih dari 70% berada pada ukuran kurang dari 80 mm. Adapun pola pertumbuhan lobster yang ditemukan adalah alometrik negatif. Laju mortalitas total lobster pasir adalah 1,66 dengan mortalitas alami dan penangkapan masing-masing 50%.

Abstract

Estimating the utilization status of kurau fish resources by other methods using limited data needs to be tried, as a comparison in formulating policies. The aim of this study was to determine the utilization status of kurau fish resources through the Length-Based Spawning Potential Ratio (LB-SPR) approach in the waters of Bengkalis Island. The method used in this study was a review of kurau fish data from July to September 2016. Data were analyzed descriptively using the LB-SPR method. The results showed that the utilization status of kurau fish resources through the LB-SPR approach in the waters of Bengkalis Island was fully moderate (still in moderate condition) with an SPR of 30%, the SL50 value was greater than the Lm value (SL50Lm) so that most of the fish caught had been worth catching. This condition indicates that fishing activities are still in a safe status, but need to be controlled so that the fish caught do not get smaller. The status of the kurau fishery is still relatively good, and can be used massively, but it needs good management to avoid overfishing.

Abstract

Rumah ikan (rumpon) di lubuk larangan Desa Tebat sudah ada dan belum diketahui pengaruhnya terhadap hasil tangkapan. Rumpon diharapkan menjadi solusi dari keberadaan lubuk larangan sebagai habitat ikan agar tetap eksis. Tujuan penelitian adalah memonitoring jenis ikan dan keanekaragamannya di sekitar rumpon. Penelitian dilakukan di Desa Tebat Kecamatan Muko-Muko Bathin VII Kabupten Bungo Provinsi Jambi pada bulan September-Desember 2021. Metode penelitian adalah survei, dengan mengumpulkan data langsung di lapangan secara random sampling menggunakan 3 alat tangkap yaitu pancing tajur, pancing joran, dan pancing katrol. Hasil monitoring rumpon lubuk larangan didapatkan 9 jenis ikan dan 3 family. Keanekaragaman di sekitar rumpon kategori sedang (H’ = 1,53), indeks keseragaman (E) ikan kategori rendah (E = 0,17), dan indeks dominasi kategori dominan (Di = 11%).

Abstract

The number of types of fishing rods in land waters makes it possible to suspect the condition and potential of fisheries by calculating the capture rate (hook rate). Research using a vertical fishing rod that is operated in the ulak river swamp, Nalo Tantan District, Merangin Regency, Jambi Province. The aim of the study was to determine the fishing rod of the straight-line vertical longline model and to analyze the catch. The research method is experimental fishing. The results showed that the vertical standard model rods' capture rate (hook rate) did not meet the standard hook rate value, with an average of 0.04 (not good). The composition of the catch is dominated by nilem fish species (O. vittatus) as much as 71% and the lowest catch of limbat fish (C. nieuhofii) as much as 2%.

Abstract

Fluktuasi pendapatan yang tidak stabil akan membuat nelayan merubah pola hidup agar dapat bertahan hidup. Salah faktor yang membuat pendapatan nelayan tidak stabil yaitu pandemi COVID-19. Pandemic ini membuat kepanikan publik di seluruh dunia saat ini. Ketidakpastian kondisi pandemi COVID- 19 saat ini sangat membuat nelayan jaring insang Kota Bengkulu frustasi untuk menjalani hidup di masa yang akan datang. Tujuan penelitian ini adalah untuk merumuskan prioritas strategi bertahan hidup nelayan jaring insang di Kota Bengkulu pasca COVID-19. Penelitian dilaksanakan pada Bulan April-Mei 2020 di Kota Bengkulu. Metode survei dipilih sebagai metode penelitian dan purpose sampling dipilih untuk teknik pengambilan data. Analisis yang digunakan yaitu strategi SWOT (Strenghts, Weakness, Opportunities, Threaths). Hasil penelitian menunjukan bahwa strategi bertahan hidup nelayan jaring insang di Kota Bengkulu pasca COVID-19 diprioritaskan pada strategi (ST) dengan memaksimalkan kelompok nelayan untuk lebih kreatif dalam melihat dinamika kondisi pandemi, bantuan pemerintah dan menjadikan keluarga dan agama sebagai motivasi agar mampu bertahan hidup pasca COVID-19. Bantuan tunai dari pemerintah sangat berguna untuk mengurangi beban hutang dan memberhentikan kegiatan illegal fishing seperti penggunaan alat tangkap trawl, sehingga saat musim ikan nelayan jaring insang mampu mengoptimalkan hasil tangkapannya.
