| Abstract: | Penelitian ini bertujuan untuk mengestimasi produktivitas unit
penangkapan, mengidentifikasi komposisi hasil tangkapan utama dan sampingan,
serta menganalisis proporsi bycatch terhadap total tangkapan pada alat tangkap
purse seine yang menedaratkan tangkapannya di PPS Belawan. Pelabuhan ini
merupakan salah satu pusat perikanan dengan aktivitas penangkapan yang tinggi,
dimana penggunaan purse seine sering kali menghasilkan tangkapan sampingan
yang berpotensi menimbulkan permasalahan terhadap keberlanjutan sumber daya
ikan. Pengumpulan data lapangan dilakukan selama Desember 2024 hingga
Januari 2025 menggunakan metode purposive sampling pada kapal purse seine
berukuran >30 GT. Data yang diperoleh meliputi jumlah tangkapan, jenis ikan,
serta informasi musim dan wilayah penangkapan. Hasil penelitian ini
menunjukkan bahwa total hasil tangkapan purse seine pada Desember 2023
hingga November 2024 mencapai 478.542 kg, terdiri dari 355.297 kg HTU (74%)
dan 123.245 kg HTS (26%). Sebanyak 18 spesies berhasil diidentifikasi, terdiri
atas 13 spesies target serta 5 spesies bycatch. Nilai CPUE tertinggi tercatat pada
Desember 2023 yaitu 64.385 kg/trip dan terendah pada Juli 2024 yaitu 20.416
kg/trip. Proporsi bycatch yang relatif tinggi terjadi pada April dan September
2024, yang bertepatan dengan masa transisi musim. HTU didominasi oleh
cakalang (Katsuwonus pelamis) sebanyak 232.652 kg. HTS didominasi oleh
layang deles (Decapterus macrosoma) sebanyak 93.557 kg. This research aims to estimate the productivity of the fishing unit, identify the composition of target and bycatch species, and analyze the proportion of bycatch to total catch from purse seine based at the Oceanic Fishing Port (PPS) of Belawan. This port is one of the major fishing hubs with high fishing activity, where the use of purse seines often results in bycatch that has a potentially negative impact on the sustainability of the marine fish resources. Field data were collected from December 2024 to January 2025 using a purposive sampling technique on purse seine vessels larger than 30 GT. The data collected included total catch, species composition, as well as seasonal and fishing ground information. The results showed that total purse seine catch from December 2023 to November 2024 reached 478,542 kg, consisting of 355,297 kg (74%) target catch and 123,245 kg (26%) bycatch. A total of 18 species were identified, comprising 13 target species and 5 bycatch species. The highest CPUE was recorded in December 2023 at 64,385 kg/trip, and the lowest in July 2024 at 20,416 kg/trip. A relatively high bycatch proportion occurred in April and September 2024, coinciding with seasonal transitions. The target catch was dominated by skipjack tuna (Katsuwonus pelamis) at 232,652 kg, while the bycatch was dominated by scad (Decapterus macrosoma) at 93,557 kg. |
