Abstract

Kegiatan penangkapan ikan oleh nelayan harus memahami mengenai ukuran dan spesies ikan yang layak tangkap. Oleh karena itu nelayan perlu mengetahui mengenai selektivitas suatu alat tangkap yang akan dioperasikan. Hal ini dapat menyebabkan kerusakan lingkungan dan dapat menyebabkan kepunahan terhadap suatu spesies ikan. Penelitian ini dilakukan dengan tujuan untuk mengetahui selektivitas alat tangkap rawai dasar di Deah Raya. Penelitian ini dilakukan pada bulan Mei-Juni 2024. Lokasi penelitian di Deah Raya, Kecamatan Syiah Kuala, Kota Banda Aceh. Metode yang digunakan pada penelitian ini adalah metode wawancara dengan data sheet. Data yang dikumpulkan adalah data primer dan data sekunder dengan jumlah data sebanyak 86. Data primer diperoleh dari hasil wawancara nelayan dan pengukuran hasil tangkapan. Data sekunder terdiri dari jumlah kapal yang beropersi dan jumlah nelayan. Analisis data pada selektivitas alat tangkap rawai dasar dianalisis dengan menggunakan formula selektivitas alat tangkap ikan Spare dan Venema 1999. Berdasarkan penelitian yang telah dilakukan terhadap selektivitas rawai dasar yang dioperasikan nelayan di Deah Raya dengan ukuran mata pancing no.7 dan no. 9, dapat disimpulkan bahwa: ada 12 spesies hasil tangkapan alat tangkap rawai dasar yang dioperasikan nelayan Deah Raya yaitu kuwe, barakuda, asuan, kakap, kerapu, gabus laut, bandeng laut kurisi, kerisi basi, todak, ayam ayam dan pandan. Rawai dasar memiliki selektivitas tinggi, hal ini didasari pada nilai selektivitas di setiap mata pancing yaitu mata pancing no.7 dengan nilai 1 dan mata pancing no.9 adalah 0,9 menunjukkan selektivitas optimal.

Abstract

Most of the Central Tapanuli Regency area is on the coast, which is part of the Indian Ocean waters and has great potential in the fishing industry, especially marine fisheries. One of the fishing gears widely used by fishermen in Central Tapanuli is the gill net. Although the amount of marine fisheries resources in Central Tapanuli is quite abundant, the catch of gillnet fishermen often fluctuates, so fishing aids are needed to increase catches, one of the efforts made is using LACUBA. This research was conducted from February to April 2024 in Sibolga Bay, Central Tapanuli. This study used a completely randomised design (CRD), with the first 30 metres of gill net treatment with LACUBA and the remaining 30 metres without LACUBA treatment with a total net length of 60 metres. The results showed that the catch of gill nets using LACUBA influenced the catch, the total catch was 16,845 grams, without LACUBA 8,290 grams for 14 times. Gill nets with LACUBA can increase catches compared to without LACUBA, due to the addition of attractants to the net, so that fish including positive phototaxis will be caught in the net, besides that fish that are looking for prey are also caught because they want to prey on their food in the gill net area.
