About the report

Cladocerans are used widely for ecotoxicological bioassays. The most commonly used endpoints are reproduction and survival. Reproduction is a sensitive indicator of toxicity, however reproduction bioassay are lengthy and time consuming tests to perform. Recent research has reported that feeding rate is a sensitive indicator of toxicity for Daphnia magna. Using a similar methodology to these tests, a feeding bioassay has been developed for the Australian tropical cladoceran Moinodaphnia macleayi, and its sensitivity tested in comparison with the standard reproduction bioassay.
