Abstract: | Summary Rainbow trout were fed the commercial diets Oregon Moist, Glencoe, Silver Cup, or Ewos, and synthetic diets containing 23% or 45% protein. After feeding the diets for 42 days, chlordane was tested against rainbow trout in static toxicity tests. LC50s (96-hr) for chlordane were 8.2, 9.1, 20, 31, 29 and 47 g/1 for the groups fed Oregon Moist, Glencoe, Silver Cup, Ewos diets and synthetic diets that contained 23 and 45% protein, respectively. The LC50 for the group fed the 45% protein diet was statistically (P=0.05) different from the values for all the other groups. Also, the values differed among groups fed commercial diets. |
