After the molt, males return to a reclusive pattern and are not as available to bass as they were when they were mating.
1. 1. The amount of 14 C glucose incorporated into the chitin of crayfish served as an indication of the rate of chitin synthesis.. 2. 2. It was found that chitin synthesis occurred at all stages of the molting cycle, including C 4 (the intermolt).. 3. 3.
