“…Similarly, in a study on the effects of dietary n‐3 series fatty acid on the fat‐soluble vitamins of pleopadal eggs and stage 1 juveniles in a freshwater crayfish ( Astacus leptodactylus ) Harlıoğlu et al. () observed that the content of δ‐Tocopherol, α‐ Tocopherol and K1 vitamin was higher in stage 1 juveniles (0.7, 79.91 and 0.5 μg g −1 , respectively) than those of pleopodal egg (0.32, 44.48 and 0.45 μg g −1 ) respectively).…”

Summary Changes in fatty acid composition, cholesterol and fat‐soluble vitamins were studied during development (fertilized eggs, yolk‐sac larvae, and after yolk resorption of shabbout, Barbus grypus). Significant differences were found in the monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFA), PUFA/saturated fatty acids (SFA), ∑n‐3 and eicosapentaenoic acid (EPA)/docosahexaenoic acid (DHA) ratios between eggs and larvae (P < 0.05). Significant differences were also observed in the C14:0, C16:1n‐7, C18:1n‐9, C18:3n‐6, C20:0, C20:4n‐6, C24:0, C24:1, C22:6n‐3 fatty acids between eggs and larvae after yolk‐sac resorption (P < 0.05). Vitamin α‐ Tocopherol and retinol content increased during embryogenesis, but changes were insignificant in retinol acetate, δ‐Tocopherol, K1, K2 and cholesterol content between eggs and larvae after yolk resorption (P > 0.05).

“…For example, Harlıoğlu, Köprücü, Harlıoğlu, Yilmaz, Aydin, Yonar, Duran and Özcan () and Harlıoğlu, Çakmak et al ., () examined the effect of 0%, 1%, 2% and 3% dietary n‐3 series fatty acids on the chemical quality and numbers of pleopodal eggs and stage 1 juvenile of A. leptodactylus broods. Results indicated that dietary n‐3 series fatty acids improved the chemical quality of pleopodal eggs (i.e.…”

Factors affecting the reproductive efficiency in crayfish: implications for aquaculture

In recent years, crayfish aquaculture industry has been developing rapidly in different regions of the world. Crayfish aquaculture is often carried out in dams, lakes and extensive pond systems. There is an increasing demand for crayfish juvenile in aquaculture sector. Therefore, it is important to know which factors affect reproductive efficiency in crayfish. In the present review, factors affecting the reproductive efficiency of crayfish are divided into two main sections, external and internal factors. Dietary lipids, phospholipids, highly unsaturated fatty acids, protein and amino acids, vitamins and carotenoids are important external factors affecting broodstock crayfish reproduction. In addition, various external (i.e. female size, stocking density, temperature, photoperiod, sex ratio) and internal (i.e. endogenous hormones) factors affect the reproductive efficiency in crayfish. This study reviews the present knowledge with the purpose of realizing the factors that are important to reach optimal crayfish nutrition, maturation and reproduction (i.e. pleopodal egg number and quality). This review will particularly be useful for crayfish farmers and crayfish hatchery units.
