Comparative analysis of morphology, growth performance and gonadal development between the hybrid crab (Scylla serrata ♀ × S. paramamosian ♂) and S. serrata

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Interspecific hybridization, through integrating genetic resources across distinct species, serves as a pivotal strategy for improving yield, stress resistance, and quality in aquacultural species. To evaluate the performance of hybrid crab (Scylla serrata ♀ × S.

Hesperidin and raffinose dietary supplementation enhances immune responses, antioxidant‐related gene expression, hematological parameters, and growth performance in juvenile common carp (Cyprinus carpio)

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract This study evaluated the individual and combined effects of two dietary immunomodulators, raffinose and hesperidin, on multiple physiological parameters in common carp (Cyprinus carpio), including growth performance, feed efficiency, hematological indices, serum immunological markers, and the expression of genes related to antioxidant capacity.

Molecular Characterisation of Endangered White‐Clawed Crayfish Populations in Southern Switzerland

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT This study investigates the phylogeography of the endangered European White‐Clawed Crayfish (WCC) Austropotamobius pallipes species complex in the main tributaries of the Po River basin in southern Switzerland and northern Italy, a diversity hotspot for this species.

BIOECONOMIC MANAGEMENT OF RED SWAMP CRAYFISH (PROCAMBARUS CLARKII) IN THE PRESENCE OF ENVIRONMENTAL EXTERNALITIES [PDF]

open access: yes
Red swamp crayfish (Procambarus clarkii) is a valuable renewable resource which creates significant negative externalities to its environment. Crayfish can cause severe crop damage by burrowing in fields and using irrigation systems to spread.

Cu accumulation, detoxification and tolerance in the red swamp crayfish Procambarus clarkii

open access: yesEcotoxicology and Environmental Safety, 2019
Copper is an essential metal but potentially toxic to aquatic animals at high levels. The present study investigated physiologically adaptive responses to waterborne Cu2+ exposure (0, 0.03, 0.30, 3.00 mg/L) in a representative species of crustaceans, the red swamp crayfish (Procambarus clarkii) for 7 d, followed by a 7-d depuration period.

Multiscale Threats Shape the Occurrence Dynamics of a Threatened Aquatic Salamander and Reveal a Possible Extinction Debt

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
The Neuse River Waterdog (Necturus lewisi) is a threatened large aquatic salamander endemic to North Carolina, USA. Site‐specific habitat quality, the proportion of developed landcover in the watershed, and annual drought intensity operate in concert to drive the species' occurrence dynamics.
