6. Factors governing the food of the darters are: (a) The 

 age and size of the fish; (b) Seasonal position of food animals; 

 (c) Special structures in the fishes (terminal or ventral mouth, 

 etc.); (d) Special types of behavior of the fish; (e) Different 

 habitats. 



7. Different food habits are not sufficient to account for the 

 distribution of the Ohio darters except locally.
