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 ...

<i>Procambarus virginalis</i> Lyko, 2017: A new threat to Iberian inland waters. [PDF]
Ecol EvolWe provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...
