Reproduction Testing Service

This test is carried out to determine the effect of a chemical on the reproductive output of Daphnia magna. Juvenile Daphnia magna, less than 24 hours old at the start of the test are exposed to the test material for a period of 21 days. Studies are performed as a semi-static with renewal of the typically three times per week, greater frequency can be used depending on the stability of the test material in the test media. 

The Reproduction Test in Daphnia assesses the chronic effects of substances on the reproductive capacity of Daphnia (typically Daphnia magna). This test is important for evaluating long-term ecological impacts on population sustainability.
