Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

First record of an introduced population of the southern lineage of white-clawed crayfish (Austropotamobius ‘italicus’) north of the Alps

Knowledge and Management of Aquatic Ecosystems, 2015
Elucidating the status of populations of endangered species of unclear origin may have important implications for conservation management. In September 2013, a population of white-clawed crayfish was discovered outside of the native ...

Optimal Dietary Dunaliella salina Supplementation Enhances Growth, Antioxidant Capacity, Immune Response, Stress Tolerance, and Carotenoid‐Based Pigmentation in Juvenile Red Swamp Crayfish (Procambarus clarkii)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
To meet the growing market demand for high‐quality red swamp crayfish (Procambarus clarkii), nutritional strategies are needed to improve both health and visual traits. The microalga Dunaliella salina, renowned for its rich natural β‐carotene content, presents a promising solution.

The ‘Pritchard Trap’: A novel quantitative survey method for crayfish

Ecological Solutions and Evidence, 2021
As crayfish invasions continue to threaten native freshwater biota, a detailed understanding of crayfish distribution and population structure becomes imperative. Nonetheless, most current survey methods provide inadequate demographic data.

Metabolic Responses to Cyclic Fasting in Juvenile Turbot (Scophthalmus maximus)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Feed accounts for the majority of aquaculture production costs, making strategies that reduce feed input without compromising growth economically attractive. This 72‐day study evaluated the effects of cyclic fasting regimens on growth, body composition, and liver transcriptome in juvenile turbot (initial body weight 5.54 g).

Effects of the Feeding Frequency of Frozen Housefly Larvae on the Growth Performance, Physiological Functions, and Intestinal Microbiota of Cherax quadricarinatus

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Optimal feeding strategies for the red claw crayfish, Cherax quadricarinatus, remain to be established. In this study, C. quadricarinatus was fed frozen housefly larva meal (Musca domestica [MD]) at different frequencies to evaluate effects on growth performance, antioxidant capacity, digestive enzyme activity, immune genes, and intestinal microbiota ...

Habitat use by the endangered white-clawed crayfishAustropotamobiusspecies complex: a systematic review [PDF]

Knowledge & Management of Aquatic Ecosystems, 2017
Understanding habitat requirements is a key part of conserving declining species, particularly when reintroductions are planned as part of the recovery strategy. The white-clawed crayfish (Austropotamobius pallipes) has undergone severe declines across its range and is now classified by the International Union for Conservation of Nature (IUCN) as ...

COMPARISON OF WHITE-CLAWED CRAYFISH POPULATIONS IN IRISH AND FRENCH STREAMS, WITH COMMENTS ON ITS FUTURE SURVIVAL IN EUROPE

Knowledge and Management of Aquatic Ecosystems, 2006
White-clawed crayfish Austropotamobius pallipes (Lereboullet) populations remain strong in Ireland across a range of river and lake habitats, but the species is in decline elsewhere in Europe where it is sympatric with alien species.
