Technical Bulletin No. 0638: Marine Chronic Bioassays – Technical Evaluations and Effluent Responses with the Bivalve Embryo/Laval Test

NCASI has a research program to technically evaluate marine chronic bioassays being adopted or proposed for use by EPA. The bivalve embryo/larval test is likely to be included when EPA issues a West Coast species marine bioassay manual. The 48-h test involves exposing bivalve embryos to test solutions through development to the first larval shell. Test endpoints include survival and normal shell development.
