Hasil penelitian terdapat 9 jenis ikan yang termasuk 9 famili antara lain Ikan Belanak (Mugilidae), Ikan Kiper (Scatophagidae), Ikan Bandeng (Chanidae), Ikan Gerabah (Sciaenidae), Ikan Lundu (Bagridae), Ikan Sembilang (Plotosidae), Ikan Laosan (Polynemidae ) , Ikan Juwi (Clupeidae), dan Ikan Janjan (Gobiidae).

The index of fish diversity are descriptively ranged from 1.09-2.0 which is classified as a low level.
