Endosulfan is aquatoxic and has an immediately effect on fish and other aquatic organism. The purpose of this study is to know of endosulfan effect on gonad of catfish (Clarias gariepinus). The exsposures were done during 8 weeks with 0 % (0 ppm) as control, 80 % (0,00216 ppm) and 90 % (0,00243 ppm) from subletal consentration that were got by toxicity test. After 8 weeks exposure to a 0% concentration (control) at testis, there were many spermatogonium in seminiferous tubules even though at the 80% and 90% concentration just a few spermatogonium, there were inflamed in cell and infiltration in tissue. Eggs diameter in the control bigger than treatment (80% and 90%). This study showed that endosulfan influence to the testis and ovary of catfish (Clarias gariepinus).

YANG BERBEDA TERHADAP GONAD IKAN
LELE DUMBO (Clarias gariepinus)Abstrak
Endosulfan adalah insektisida yang memiliki efek langsung pada ikan dan
kehidupan air lainnya. Tujuan penelitian ini adalah untuk mengetahui pengaruh
pemaparan endosulfan dengan konsentrasi yang berbeda terhadap gonad ikan lele
dumbo (Clarias gariepinus). Pemaparan dilakukan selama 8 minggu dengan
konsentrasi sebesar 0% (kontrol), 80% (0,00216 ppm) dan 90% (0,00243 ppm)
dari konsentrasi subletal yang diperoleh pada uji toksisitas. Pada testis dengan
konsentrasi 0% menunjukkan jumlah spermatogonium sangat padat di tubulus
sedangkan pada konsentrasi 80% dan 90% jumlah spermatogonium sangat rendah,
terdapat sel radang dan infiltrasi jaringan. Pada ovarium dengan konsentrasi 0%
menunjukkan diameter telur lebih besar sedangkan pada konsentrasi 80% dan
90% diameter telur lebih kecil. Penelitian ini menunjukkan bahwa endosulfan
mempengaruhi ovarium dan testis ikan lele dumbo.

Endosulfan is aquatoxic and has an immediately effect on fish and other aquatic

consentration that were got by toxicity test. After 8 weeks exposure to a 0%
concentration (control) at testis, there were many spermatogonium in seminiferous
tubules even though at the 80% and 90% concentration just a few
spermatogonium, there were inflamed in cell and infiltration in tissue. Eggs
diameter in the control bigger than treatment (80% and 90%). This study showed
that endosulfan influence to the testis and ovary of catfish (Clarias gariepinus).
