Abstract
A review of 108 papers on food habits of fishes, amphibians and reptiles in eastern United States points to the importance of crawfishes in the diet of some of these animals. Knowledge of the productivity and reproductive potentials of crawfishes is given along with brief notes on each of the 12 most important species indicated in the food habits studies reviewed. The need for additional work on crawfishes in order that they be utilized to fullest advantage in wildlife management is stressed.
