Flowthrough fecundity test with Nitocra spinipes (Harpacticoidea Crustacea) for aquatic toxicity
A sublethal flowthrough fecundity test with the euryhaline harpacticoid copepod, Nitocra spinipes, has been developed as a complement to the acute toxicity test (for 48 or 96 hr LC50) with the same species. Bacterial suspension as feed and test water are continuously fed by a peristaltic pump to the system. Newly fertilized females with ovigerous bands are harvested from laboratory cultures and put into the test vessels at the start of the experiment. They are then exposed to a series of concentrations of chemicals or industrial effluents for 13 days. The amount of live offspring (metanauplia and copepodids) are recorded and an EC50 for fecundity is calculated. The report gives a detailed technical description of the test system and presents the results from 11 tests with pure chemicals (Zn, Cd, As, and pentachlorophenate) and six industrial effluents (pulp industry, textile industry, and refinery) in salinities ranging from 3 to 25%.
