The {….} – day chronic toxicity of {test chemical} to early life stage of {common name and scientific name} was studied under {static renewal/flow through} conditions.  Fertilized eggs/embryos {enter number of eggs/embryos used, age or stage of development} of {species} were exposed to {control, solvent control, and test chemical nominal/measured concentrations} of x1, x2, x3, ….xn mg a.i./L.  The test system was maintained at … to … ēC and a pH of … to …  The {….} – day EC50 and NOEC values, based on mortality/sublethal effects {specify), were … and .. mg a.i./L respectively.   The sublethal effects included were … [provide details of treatment-related effects on number of embryos hatched, time to hatch, mortality of embryos, larvae, and juveniles, time to swim-up, measurement of growth, incidence of pathological, histological, or behavioral effects, other observation].   The most sensitive end point was {specify}.


This toxicity study is classified as {acceptability classification e.g. acceptable/unacceptable/ supplementary) and (satisfies/does not satisfy} the guideline requirement for early life toxicity study with fish.
