Toxicity tests using standard effluent test procedures were conducted with ceriodaphnia dubia and fathead minnows and four endangered fish species: bonytail chub (Gila elegans), Colorado squawfish (Ptychocheilus Lucias), razorback sucker (Xyrauchen Texanus) and Gila topminnow (Poeciliopsis occidentalis). We conducted 7-d survival and growth studies with embryo-larval fathead minnows and analogous exposures using the listed species. Survival and reproduction were also determined with C. dubia. Tests were conducted with: (1) carbaryl; (2) ammonia; and (3) a mixture of carbaryl copper, 4-nonylphenol, pentachlorophenol, and permethrin. This study was conducted with fish species that have not been typically tested so factors such as handling procedures, optimum feeding rates, optimum test temperature, expected test to test variation and expected survival or growth have not been previously documented, and therefore results of this study should be interpreted cautiously.
