Culture health of Ceriodaphnia dubia was evaluated for organisms cultured with all combinations of three foods and three waters. The criteria used to assess health of cultures included adult and neonate weights, time required to produce first broods, neonate production, adult survival, and resistance to hexavalent chromium. Diet‐water combinations that produced the most neonates were not found to produce adults that were more resistant to chromium than those that produced fewer neonates. Of those evaluated, a diet of Selenastrum capricornutum and a yeast‐trout food‐cereal leaf mixture was best for culturing and testing Ceriodaphnia. The best tested synthetic culture water was a mixture of nine parts reconstituted hard water and one part bottled mineral water.
