Abstract

Sensitivity of the three freshwater fish, Cyprinus carpio, Oryzias latipes (wildtype indigenous to Korea), and O. latipes (Japanese killifish) to 30 pesticide formulations were studied in terms of 48 hr $LC_{50}$ determined with the static method. The correlation between C. carpio and O. latipes (Japanese killifish) was higher than that between C. carpio and O. latipes with correlation coefficients of 0.89 and 0.80, respectively. The sensitivity of O. latipes and O. latipes (Japanese killifish) to pesticides showed very high correlation with a coefficient of 0.93. Therefore, it is suggested that the acute toxicity data concerning O. latipes (Japanese killifish) could represent those C. carpio or O. latipes which are indigenous species in Korea. Also, it is found that the present protocol for the toxicity test with carp in Korea has difficulties in maintaining the proper concentration of dissolved oxygen in the test chamber because of the abrupt decrease of dissolved oxygen to 2mg/l, which is not acceptable according to general guidelines of foreign countries.

잉어(C. carpio), 송사리(O. latipes), 일본산 송사리(O. latipes)등 3종의 담수산어 류에 대한 30개 농약의 급성독성$(48hr-LC_{50})$을 평가하여 각 어종간 농약에 대한 감수성의 상관관계를 비교하였다. 어종간 농약감수성의 상관관계는 잉어와 송사리는 r=0.80, 잉어와 일본산 송사리는 r=0.89로 비교적 높은 편이나, 송사리와 일본산 송사리의 상관관계는 r=0.93으로 매우 높았다. 따라서 일본산 송사리의 실험결과로 잉어 및 송사리의 농약 감수성을 예측할 수 있을 것으로 생각되었다. 그리고 우리나라의 잉어에 대한 어독성실험 지침은 실험수조내의 DO가 2mg/1 정도까지 떨어지므로 실험지침에 대한 검토가 있어야 할 것이다.
