An experiment was conducted to measure the survival and growth of juvenile Dungeness crabs ( Cancer magister ) when fed purified crustacean diets in intensive laboratory culture. Wild‐caught juvenile crabs were held individually and fed either a casein‐based diet previously used for lobster experimentation (diet BML‐81 S), a crab protein‐based diet (HFX‐CRD‐84), or a closed‐formula commercial fish (trout) diet. Diets BML‐81 S and HFX‐CRD‐84 have been proposed as possible general crustacean reference diets. The crab protein‐based diet appeared to be more attractive to the crabs, but after a 90 day experimental period there were no significant differences ( P < 0.01) in growth or survival between crabs fed the proposed reference diets; however, survival on the trout diet was significantly reduced. Results are discussed in relation to the rearing conditions and the composition and physical characteristics of the diets.
