Question:
How do you determine the gender of a crayfish?



Replies:
Pennak, Freshwater Invertebrates, should be available in a good library. It says "there is no difficulty distinguishing the sexes," however, it refers to fairly minute details. Generally males have larger chelae (claws) and narrower abdomens. The text goes on to describe a number of detail differences.
