Conclusions:
48 h TL50 of FAT 20035/A to trout fish was found to be 6.3 mg/l.
Executive summary:

An acute fish toxicity test performed following a internal method equivalent or similar to OECD test guideline 203 using trout fish. Fish were exposed to FAT 20035/A for 48 hr to determine the TL values. Total 8 fishes were used per concentration (2, 20 and 100 mg/l) and observed for 24 and 48 h. All fishes were survived at 2 mg/l concentration however all animals were died at 20 and 100 mg/l contration. Based on the study results, the TL0, TL50 and TL100 of FAT 20035/A in trout fish was 2, 6.3 and 20 mg/l, respectively.
