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 ...

A contribution on the morphometrics of the thick-clawed crayfish Pontastacus pachypus (Rathke, 1837) (Decapoda, Astacoidea, Astacidae) [PDF]

Zoosystematics and Evolution, 2023
The thick–clawed crayfish Pontastacus pachypus (Rathke, 1837) is an endangered, and the least known, crayfish species in Europe. Currently, detailed information regarding the morphology, ecology and reproduction of thick–clawed crayfish is outdated. This

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 ...

Influence of distance from source population and seasonality in eDNA detection of white‐clawed crayfish, through qPCR and ddPCR assays

Environmental DNA, Volume 5, Issue 4, Page 733-749, July 2023., 2023
Abstract The white‐clawed crayfish (Austropotamobius pallipes) is an emblematic taxon of European rivers, found mainly in oxygenated streams, known to be an excellent indicator of river quality. Since several decades, the population of A. pallipes declined in relation to anthropogenic pressure, habitat loss, and competition with pests (invasive ...

Natural Biota’s Contribution to Cultured Aquatic Animals’ Growth in Aquaculture Cannot Be Ignored

Aquaculture Research, Volume 2023, Issue 1, 2023., 2023
The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets.
