Understanding effects of photoperiod on the reproductive efficiency and physiological responses of Pontastacus leptodactylus is important for successful management of the crayfish hatcheries. Spermatozoal number, gonado-somatic index (GSI), hepatosomatic index (HSI), testicular index (TI), vas deferens index (VDI), and total protein, amino and fatty acid profiles of the hepatopancreas were evaluated in male narrow-clawed crayfish P. leptodactylus.

- Sperm quality is crucial for successful reproduction in crustacean aquaculture, with spermatozoa count in spermatophores serving as a key indicator.
- Different incubation times and temperatures significantly impact spermatozoa extraction from the ductus deferens in the species Pontastacus leptodactylus.
- Optimal results show that incubating at 23°C for 4 hours yields the highest number of spermatozoa, while higher temperatures reduce extraction effectiveness.
The differences in the crista dentata structure of the ischium of third maxilliped in different size Astacus leptodactylus (36-80 mm carapace length) were investigated. The results showed that four different types of crista dentata structure and teeth number occur in the third maxillipeds of A. leptodactylus.
