Description of key information
The LC50of 96 h of test substance FRET 11-0230 on Zebrafish species was 8.431 mg/L (95% confidence limits of 7.591~9.307 mg/L) based on the nominal concentration under the test conditions in this study, according to OECD test guideline 203. Treated group of test substance with nominal concentration of 6.0, 7.2, 8.6, 10.3, 12.4, 14.9 mg/L (geometric series with a factor of 1.2) and blank control group were designed in the definitive test. 10 fish were used in each group. The duration of test was 96 hours in a semi-static exposure system with renewed test solution every 48 hours. The measured concentrations were within the range of 82.2%~96.5% of the nominal concentration. According to the statistical analysis, the LC50of 96 h was 8.431 mg/L and 95% confidence limits was 7.591~9.307 mg/L based on the nominal concentration.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
