A series of artificial diets was evaluated in terms of growth, survival, and normalized biomass during three‐month growth studies utilizing juvenile lobsters. The effects of both texture and the addition of specific nutrients were examined. An increase in normalized biomass resulted from the addition of water soluble vitamins and minerals as well as with the addition of shrimp meal. The effect of shrimp meal in the diet could not be duplicated by the addition of chitin or glucosamine. A number of jell‐textured diets produced better growth rates than similar hard pelletized diets but animals on the soft diets suffered a high percentage of mortalities by the end of the experiment. These results are discussed in comparison with those of other investigators using lobsters as test animals.
