Abstract
AbstrakThe use of pesticides in agriculture continues to increase. One of the classifications of pesticides is organochlorine endosulfan insecticide that can cause river pollution. One type of fish that is often cultivated in ponds is tilapia. River pollution can trigger stress and even fish death. The stress level of the fish can be seen from the value of its blood sugar levels. This research was conducted on March 20 - April 28, 2021, in Microbiology Laboratory and Anatomy-Aquaculture Laboratory, Faculty of Fisheries and Marine, Universitas Airlangga, to determine the toxicity effect of sublethal endosulfan organochlorine insecticide on blood sugar level value and tilapia seed life rate. This study used experimental methods with CRD through exposure to different organochlorine concentrations, namely P0 (0%), P1 (10%), P2 (30%), P3 (50%), P4 (70%) with four replays. Analysis of the data was processed using ANOVA and DMRT, which showed that sublethal toxicity of endosulfan organochlorine insecticides had an effect (p<0.05) on blood sugar levels and the level of tilapia seed resistance. Using only a concentration of 10% has increased blood sugar levels significantly on the 7th day and continues to increase until the 28th day (114.50 mg/dL). Also, the level of fish life insecurity indicates a value below the Indonesian National Standard (72.50 %).
