Standardization of pleopodal egg number in narrow-clawed crayfish ( Pontastacus leptodactylus Eschscholtz, 1823)

Invertebrate Reproduction & Development
In this study, the effects of certain biotic factors (length, presence of lesions) and abiotic factors (month of fishing and fishing area) on pleopodal egg production of Pontastacus leptodactylus (Eschscholtz, 1823) were examined to determine the optimal productivity of spawned female crayfish for aquaculture purposes.
