Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives. [PDF]
Aquac NutrReproductive maturation remains a central bottleneck in crustacean aquaculture, as ovarian development dictates broodstock quality, fecundity, and larval viability. This review synthesizes current knowledge on the physiological regulation of ovarian maturation in decapod crustaceans, emphasizing the interplay of hormones, nutrients, and environmental ...
