| Abstract: | The composition of the lateral muscles of first-year roach was studied using histological techniques. It was found that all samples had significantly higher levels of red muscles in the hindermost regions, and these levels rose as the fish became larger. Fish from a running water habitat contained significantly more red muscle than fish of the same age from still water, and it is suggested that this results from muscle development during natural'training'to water flow. |
