Overfishing and Overcapacity Small Scale Fisheries in Semarang City

Abstract

Fisheries in Semarang City are dominated by small-scale fisheries. This is indicated by the use of the largest fishing fleet of 10 gross tons operating near the coast. This study aims to analyze the status of small-scale fisheries in Semarang City for sustainable management. Sustainable management is management that guarantees the availability of natural resources and environmental services for future generations. The study was conducted for three months, namely September-November 2018 in the coastal waters of Semarang City, which was part of the Fisheries Management Region (WPP) 712. The method used in this study is the analysis of time series surplus production, namely data from the catch (ton/year) and the number of fishing gear (unit) within 10 years (2007-2016), to calculate the catch per-unit effort (CPUE), maximum sustainable yield (MSY), optimum effort (fopt), utilization rate (TP) and capacity level (TK). This study was obtained results of a downward trend in CPUE; the existing fishery catch or production in 2016 has exceeded the MSY value is 479 tons/year (Schaefer) and 439.11 tons/year (Fox); utilization rate of more than 100% which is 108-127% (Schaefer) and 118-138% (Fox), so that small-scale fisheries in Semarang City are at the level of over-exploited. Based on the fopt analysis, the number of fishing gear used (fexisting) has exceeded the optimum effort with a fishing capacity exceeding 100%, so that small-scale fisheries in Semarang City have experienced overcapacity.

ANALISIS BIOEKONOMI PERIKANAN LAUT DI PESISIR KOTA SEMARANG (Bioeconomic Analysis of Marine Fisheries in The Coastal City of Semarang)

“…Mayoritas nelayan di pesisir Kota Semarang merupakan nelayan tradisional dengan oneday fishing. Ukuran armada perikanan tangkap di Kota Semarang paling besar adalah 10 GT dengan lokasi beroperasi di perairan dekat pantai (Malik et al 2019). Meskipun berskala usaha kecil, namun perikanan tradisional memiliki peranan penting terkait penyediaan sumber pangan dunia, sumber pendapatan penduduk maupun kepentingan pelestarian budaya (Gough et al 2020).…”

“…Hal ini dapat menjadi salah satu indikasi bahwa stok sumberdaya ikan di pesisir Semarang telah mengalami tekanan sehingga produktivitas perikanan laut (yang bersifat one-day fishing) mengalami penurunan. CPUE yang menurun mengindikasikan operasi penangkapan semakin tidak efisien (Wijayanto et al 2016, Malik et al 2019.…”

Pengelolaan Perikanan Skala Kecil di Perairan Pesisir Kota Semarang

“…Menurut Malik et al (2019a); Malik et al (2019b); Malik (2020) perikanan di Kota Semarang 100% merupakan perikanan skala kecil, yaitu perikanan dengan nelayan yang menggunakan kapal perikanan sampai dengan 10 gros ton (GT). Alat tangkap yang 168 JIPI, Vol.…”

“…26 (2): 167176 beroperasi di perairan Kota Semarang dengan kapal perikanan sampai 10 GT ialah Gill Net, Arad, Bagan Perahu, Trammel Net, dan Bubu. Sumber daya perikanan skala kecil di Kota Semarang mengalami tekanan yang tinggi (Malik et al 2019a;Malik et al 2019b;Malik 2020). Hal ini ditandai dengan perkembangan jumlah alat tangkap (effort) yang meningkat, sementara hasil tangkapan ikan (catch) cenderung menurun (Gambar 1).…”
