Abstract

The recommended species in fish acute toxicity test for pesticide registration in korea are common carp (Cyprinus carpio), killifish(Oryzias latipes) and loach(Misgurnus anguillicaudatus). But most of fish toxicity was evaluated using common carp. The common carp has several problems such as difficulty of room breeding, difference of sensitivity to breeding condition, limited experimental period, etc. For that reason, it is necessary to reexamine of test species. The present study investigated the sensitivity and correlation of $LC_{50}$ values that determined using the acute toxicity test with common carp and killifish. And this study is a realistic approach to evaluated appropriate species for fish acute toxicity test of pesticide. As a result, correlation coefficient(R) of the commom carp and killifish was high correlation of 0.8480 and the $LC_{50}$ values was not significant in the interspecies sensitivity. When the $LC_{50}$ values of common carp and killifish was compared with fish toxicity guideline in Korea, fish toxicity class has fluctuated in 18 pesticides with not very special tendency. Therefore, it is necessary to review of killifish has more advantage to standardization of fish culture and in the side of correlation and sensitivity of acute toxicity.
