Abstract A growing concern for use of local species for toxicity testing leads to the need to create toxicity data banks for these species. In order to have healthy animals to conduct the tests, procedures for maintenance of stock cultures of these species should be developed. The most widespread daphnid in Australia, Daphnia carinata, is considered to be one of the most suitable for toxicity testing of contaminants entering Australian freshwaters. However very little data are available on the culture requirements of the species. In this study different types of food were tested: Chlorella vulgaris cultured in two different media - Keating and Tamiya, Chlorella pyrenoidosa cultured in the same two media, and a suspension of trout pellets. Intrinsic rates of natural increase of individual cultures of D. carinata were determined from "life tables". The best food from among those tested were C. pyrenoidosa cultured in either Keating or Tamiya medium. Two different procedures of individual cultures are proposed for the maintenance of D. carinata for use in toxicity testing, based on tests conducted using different culture volumes
