Abstract

Penelitian ini bertujuan untuk mengetahui keanekaragaman hasil tangkapan bagan apung di perairan Danau Maninjau, Kabupaten Agam, Sumatera Barat. Penelitian dilaksanakan pada tanggal 1 Mei sampai dengan 21 Mei 2023 dengan metode survei yaitu melakukan pengamatan secara langsung pada objek penelitian. Sampel bagan yang diambil untuk penelitian berjumlah 3 alat tangkap bagan dengan ukuran 5m x 5m dan dilakukan selama 10 trip. Data yang dihimpun meliputi komposisi ikan, jumlah total ikan (ekor), jumlah per jenis (ekor), berat per jenis (gr), berat total ikan (kg) dan ukuran per jenis ikan (cm). Data yang diperoleh dari penelitian ini dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa komposisi hasil tangkapan bagan apung terdapat empat spesies ikan dengan komposisi tertinggi ikan wader (Rasbora sp) sebanyak 54.518 ekor (main catch) dan komposisi hasil tangkapan terendah yaitu ikan betutu (Oxyeleotris marmorata) sebanyak 64 ekor sedangkan ikan nila (Oreochromis niloticus) sebanyak 2.199 ekor (bycatch) dan ikan cere (Gambusia affinis) sebanyak 182 ekor (discard). Indeks keanekaragaman (H’) bernilai 0,19 termasuk kedalam kategori rendah. Indeks keseragaman (E) diperoleh dengan nilai 0,14 termasuk dalam kategori rendah. Dan indeks dominansi (C) bernilai 0.92 dan termasuk kedalam kategori tinggi. This study aims to determine the diversity of Lift net catches in the waters of Lake Maninjau, Agam Regency, West Sumatra. The research was carried out from May 1 to May 21, 2023 with a survey method, namely making direct observations on the object of research. The chart samples taken for the study amounted to 3 chart fishing gear with a size of 5m x 5m and were carried out for 10 trips. The data collected include fish composition, total number of fish (tail), number per type (tail), weight per type (gr), total weight of fish (kg) and size per type of fish (cm) as well as environmental parameters. The data obtained from this study were analyzed descriptively and presented in the form of tables and graphs. The results showed that the composition of the floating chart catch was four species of fish with the highest composition of wader fish (Rasbora sp) as many as 54,518 heads (main catch) and the composition of the lowest catch, namely betutu fish (Oxyeleotris marmorata) as many as 64 heads while tilapia (Oreochromis niloticus) as many as 2,199 heads (bycatch) and cere fish (Gambusia affinis) as many as 182 heads (discard). The diversity index (H') of 0.19 is in the low category. The uniformity index (E) obtained with a value of 0.14 belongs to the low category. And the dominance index (C) is 0.92 and is included in the high category.
