DISCUSSION AND SUMMARY 



The way in which fishes become poisonous is not yet thoroughly un- 

 derstood, although an ever increasing number of data indicates that the 

 process is a result of their food habits. A more complete discussion of 

 this subject has been published by Halstead and Bunker (1954). There 

 are probably many factors governing the degree of toxicity of a fish, viz., 

 abundance of certain types of food, availability of certain organic chemi- 

 cal constituents in that food, and the physiology of the fish.
