• The development of a rapid response toxicity bioassay based on the feeding rate of the tropical cladoceran Moinodaphnia macleayi (PDF 1.76 MB)

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.
