Abstract:
Surfactant is active agent in detergent may affect pollution in the water. The purpose of this experiment is to examine the effect of surfactant on growth, survival, and histopathology of gill, kidney, and liver tissues on Nile tilapia (Oreochromis niloticus) culture. The aquarium with 70 x 40 x 45 cm was used. Fish with 8,46 ± 0,1 cm in total length was used. Stock density was 40 fishes per aquarium. The different of surfactant concentration used in this experiment were as follow: A) 1,5 mg/L; B) 3,0 mg/L; C) 4,5 mg/L; and D) 6,0 mg/L. Each treatment consisted of tree replicates. The experiment was conducted for 2 months. The result showed that The highest of survival (98.33 ± 2.89 %) at B treatment was found, and then followed by C, A and D treatments were 90.00 ± 6.61%, 89.17 ± 9.46%, and 89.17 ± 6.29 % (P>0,05), respectively. The body weight (6.5 ± 0.7 g) was the highest at D treatment then followed by B, and C were 5.72 ± 1.54 g, 6.5 ± 1.39 g and 5.06 ± 0.83 g (P>0.05), respectively. The kinds of damaged of gill, kidney, and liver tissue found such as lesion, swelling, vacuolation, blood, and necrosis were observed
