WebThe fish early life-stage toxicity test (FELS; OECD TG 210; OECD, 2013a) is the most commonly used test to establish chronic fish toxicity, i.e. to determine lethal and sublethal effects of a chemical on early life stages of fish (embryos, larvae, juvenile fish). The endpoints are hatching success, abnormal appearance, abnormal behaviour ...
