Fish early-life stage toxicity test
WebTests done on early-life stages of fish are intended to define the lethal and sub-lethal effects of chemicals on the stages and species tested. OECD 210 also helps provide a value for the estimation of the chronic lethal and sub-lethal effects of the chemical on other fish species. Common Test Organism: Danio rerio (zebrafish) WebJan 19, 2024 · Fish early life stage (ELS) tests (Organisation for Economic Co-operation and Development test guideline 210) are widely conducted to estimate chronic fish toxicity. In these tests, fish are exposed from the embryonic to the juvenile life stages.
