Pemetaan Spasial Dan Temporal Status Pemanfaatan Ikan Kerapu Di Perairan Teluk Saleh, Nusa Tenggara Barat

Abstract

The Saleh Bay is one of the bays in West Nusa Tenggara utilized as the grouper fishing ground. However, in the previous spawning potential ratio study, some grouper species have been overexploited in Saleh Bay. This study aimed to estimate the status of grouper utilization with a catch per unit effort (CPUE) approach and the spatio-temporal fishing intensity of grouper in fishing grounds in Saleh Bay. Data were gathered using the fish landing data and geo-reference of fishing ground grouper in Saleh Bay. This study used several methods: descriptive analysis, catch per unit effort, and spatial-temporal analysis. The result showed that the catch unit effort positively impacts production, with the increasing trend of grouper fishing in Saleh Bay waters. The CPUE value in 2016 was 2.82 kg/trip, while in 2020, it increased to 3.99 kg/trip. Spatially and temporally, fishers caught grouper around small islands such as Liang Island, Dempu Island, Lipan Island, Takat Nusa Pudu, and Rakit Island. The highest intensity of grouper fishing around the marine protected area, namely Rakit Island, Liang Island, and Ngali Island.

“…), and mackerel scad (Decapterus spp. ), and artificial lures [61]. In addition to using fresh bait, troll lines in Saleh Bay also employ artificial lures (made of plastic that resembles a fish), which accounts for a very high proportion of epinephelid catches.…”

“…Further analysis of the five main fishing methods (bottom longline, speargun, handline, drop line, and troll line) revealed that bottom longlines yielded the highest CPUE. This is likely due to the nature of bottom longlines, which can deploy 100-250 hooks in a single setting [61]. This number is much greater than the single line and hook used in handlines or troll lines.…”

“…Furthermore, the PERMANOVA analyses of the species composition among the five fishing methods identified significant differences (p = 0.001), with the largest differences between the bottom longlines and spearguns, with some overlap between the other methods, indicating that all five fishing methods catch some common species. This can be attributed to at least two factors, the overlap in fishing grounds for the different methods (as indicated by [61]) and the use of the same type of bait and lure in bottom longline, handline, and troll line. Competition among fishing methods, as evidenced by the overlap in species composition across these methods, is a common characteristic in small-scale, multi-gear, and multi-species fisheries.…”

Karakteristik Ikan Kerapu Di Pasar Arumbai Ambon

“…Jika dibandingkan dengan penelitian ini, ukuran maksimal kedua jenis ikan tersebut tidak berbeda jauh. Dengan pemahaman ini, terungkap bahwa ikan kerapu yang memiliki karakteristik ukuran dan bobot maksimal dapat menjadi landasan penting dalam pengelolaan dan pelestarian sumber daya ikan kerapu (Darmawan et al, 2022). Dengan memahami keberadaan serta ukuran tubuh ini, praktisi perikanan dan pengelola sumber daya laut dapat mengambil langkah-langkah yang lebih terarah dalam menjaga keseimbangan populasi ikan kerapu di berbagai habitat dan perairan (Blount et al, 2021;Niz et al, 2023;Hehanussa, 2024 ).…”

Ecosystem Approach to Fisheries Management Status At West Kei Kecil Small Island Park, South East Maluku Regency

“…Secara ekologis, penangkapan ikan di bawah Lm berpengaruh terhadap keseimbangan rantai makanan di perairan (Syadli et al 2022). Darmawan et al (2022) berpendapat kepatuhan terhadap peraturan pemerintah mengenai ukuran ikan dapat mempertahankan kelestarian sumberdaya ikan. Kurangnya pemahaman keberlanjutan sumberdaya ikan harus menjadi perhatian pengelolaan perikanan.…”
