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 ...

Application of D-Crustacean Hyperglycemic Hormone Induces Peptidases Transcription and Suppresses Glycolysis-Related Transcripts in the Hepatopancreas of the Crayfish Pontastacus leptodactylus - Results of a Transcriptomic Study. [PDF]
PLoS ONE, 2013 The crustacean Hyperglycemic Hormone (cHH) is a neuropeptide present in many decapods. Two different chiral isomers are simultaneously present in Astacid crayfish and their specific biological functions are still poorly understood.

The amount of environmental DNA increases with freshwater crayfish density and over time
Environmental DNA, 2022 Over the last years, the analysis of environmental DNA (eDNA) has become an important approach to investigate species communities. Due to its non‐invasive nature and high sensitivity, this method is excellently suited to monitor the occurrence of ...

<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 ...
