Pengaruh Bioakumulasi Endosulfan Terhadap Pertumbuhan Ikan Mas (Cyprinus carpio LINN)

Abstract

This research was done in order to determine the effect of endosulfan biaccumulation on the growth of carp (Cyprinus carpio). This research was conducted in 40 l of glass aquaria, the initial weight of carp was 0.810.098 g/fish, and the pesticide endosulfan with active ingredient of 350 g/l was used as test solution. Preliminary research was conducted with bioassay test to assess LC50-96h of endosulfan for carp, and then the fish were exposed to some series of exposure concentration, those are 10; 30; and 50% of LC50-96h value or 0.24; 0.72; and 1.2 g/l for 12 weeks. Endosulfan residue analysis in the water and the body of the fish was conducted after: 0, 4, 12, 24, 48, 96, 144, 192, 264 of exposure hours by using liquid gas chromatography (LGC). Body weight of fish was measured weekly. This study resulted that endosulfan was very toxic to the carp with LC50-96h value was 2.42 (2.206-2.652) g/l. Endosulfan bioaccumulation of exposure concentration of 0.24; 0.72; and 1.20 g/l were 67.93; 119.21; and 141.19 g/kg respectively. Bioaccumulation of 119,21g/kg significantly inhibit the growth of carp.
