Uji Toksisitas Bahan Aktif Niklosamida Terhadap Crustacea Sebagai Water Treatment dalam Budidaya Udang Vannamei (Litopenaus vannamei)

Abstract

This study aims to determine the level of toxicity of the active ingredient based niclosamide on the value LC50- 24h against crustaceans and the duration of the residual effect of niclosamide in water. Methods This study used a completely randomized design with 4 different concentration levels and 0 ppm as a control. Toxicity tests using a concentration of 1.7783; 3.1623; 5.6235 and 10.0002 ppm. To determine the duration of the test using the residual effects of detoxification. In the detoxification test stick with a concentration in the toxicity test. Probit analysis results in test animals showed values (LC50) - 24 hours amounted to 3.6282 ppm, while the length of the residual effects of niclosamide in water for 96 hours.
