Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives. [PDF]

Aquac Nutr
Reproductive 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 ...

Cloning and functional characterization of a TMC-like channel gene and protein in the crayfish Astacus leptodactylus (Eschscholtz, 1823) (Decapoda: Astacidea: Astacidae)

Journal of Crustacean Biology, 2023
Ion channels gated selectively by mechanical stimulus are the key elements of mechanosensation. Several genes have been associated with putative mechanosensitive ion channels or mechanosensitive channel complexes.

Optimal Tryptophan Improved Growth and Regulated Agonistic Behavior of Oriental River Prawn, <i>Macrobrachium nipponense</i>. [PDF]

Aquac Nutr
Tryptophan, recognized as the third limiting amino acid, plays a crucial physiological function. The optimal tryptophan requirement for oriental river prawn (Macrobrachium nipponense) was assessed, and its impact on agonistic behavior was evaluated in this study. An 8‐week feeding trial was implemented with six different tryptophan levels: 0.07%, 0.17%,

Procambarus virginalis Lyko, 2017: A new threat to Iberian inland waters. [PDF]

Ecol Evol
We 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 ...
