Abstract

The aims of this research were to determine gonadal development stage and fecundity of fish inhabited the swamp pond of Bangkau Lake. Fish sampling was conducted in October 2012 (the peak dry season) in the three units of swamp pond. The number of fish that analyzed was by 30 specimens from each species. The range of gonadal development stage of female fish that found in swamp ponds was II-V; where the most specimens were mature (stage IV-V). Fecundity of fish ranged from 8,994-17,988 eggs (striped snakehead); 8,667-17,104 eggs (snakehead); 2,648-14,566 eggs (climbing perch); 4,635-10,594 eggs (snakeskin gourami); and 1,324-2,648 eggs (three spot gourami).


Abstrak


Penelitian bertujuan menentukan tingkat kematangan gonad dan fekunditas ikan penghuni kolam rawa di rawa Danau Bangkau. Pengambilan sampel ikan dilaksanakan pada bulan Oktober 2012 (puncak musim kemarau) di tiga unit kolam dengan metode sampling. Jumlah ikan contoh yang dianalisis sebanyak 30 ekor setiap jenis. Tingkat kematangan gonad ikan betina yang tertangkap di kolam rawa berkisar pada tingkat II-V. Sebagian besar ikan yang tertangkap di kolam rawa berada pada kondisi matang gonad (TKG IV-V). Fekunditas ikan yang matang gonad menunjukkan kisaran 8.99417.988 telur (gabus), 8.667-17.104 telur (toman), 2.648-14.566 telur (betok), 4.635-10.594 telur (sepat siam), dan 1.3242.648 telur (sepat rawa).
