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

The Substitution of Soybean Lecithin With Lysophospholipids Promoted the Growth Performance, Lipid Metabolism, and Reduced Dietary Lipid Inclusion for Pacific White Shrimp (Litopenaeus vannamei)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
This study evaluated the feasibility of replacing soybean lecithin (SBL) with lysophospholipids (LYLs) in the diet of Pacific white shrimp, Litopenaeus vannamei. Five isonitrogenous diets were formulated as the control diet with 15 g/kg soybean oil and 15 g/kg SBL inclusion (LYL‐0), three SBL‐substituted diets with 1/3, 2/3, and 3/3 of SBL substituted ...

The Red Alien vs. the Blue Destructor: The Eradication of Cherax destructor by Procambarus clarkii in Latium (Central Italy)

Diversity, 2018
Cherax destructor is a crayfish endemic to south-eastern Australia and one of the last alien crayfish to be introduced in Italy. In the Laghi di Ninfa Natural Reserve (Latium region, Central Italy), the species was probably introduced in 1999, but only ...

Crayfish invading Europe: the case study ofProcambarus clarkii [PDF]

Marine and Freshwater Behaviour and Physiology, 2006
The red swamp crayfish, Procambarus clarkii, native to northeastern Mexico and southcentral USA, is today the dominant macroinvertebrate in several European countries. While the first introduction of this species into Spain is well-documented, little is known about its pathways of invasion and the reason for its rapid spread in several European ...

Dietary Protein and Lipid Levels Affect Growth Performance, Antioxidant Capacity, and Metabolism in Postlarval Macrobrachium rosenbergii

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
The protein‐to‐energy ratio is crucial for the overall performance of Macrobrachium rosenbergii postlarvae, yet the optimal range remains undetermined. We formulated nine experimental diets in a 3 × 3 factorial design, encompassing three graded protein levels (45.83%, P46; 49.03%, P49; 52.23%, P52) and three graded lipid levels (6.07%, L6; 8.03%, L8 ...

Effects of light intensity and photoperiod on ovarian development of Procambarus clarkii (Girard, 1852): Comparative proteomics analysis, growth performance and biochemical

Aquaculture Reports
Physiological and biochemical analysis showed that the decrease in photoperiod could inhibit the growth and ovarian development of Procambarus clarkii, while the decrease in light intensity could promote the growth of P.

SPERMIOGENESIS IN THE CRAYFISH (PROCAMBARUS CLARKII) [PDF]

The Journal of Cell Biology, 1961
The sperm of the crayfish, Procambarus clarkii, is relatively simple among decapod sperm and was described in the first paper of this series (28). The present paper details the development of this sperm as followed with the light and electron microscopes. The process is divided into six stages for purposes of description.

Can native species crucian carp Carassius auratus recognizes the introduced red swamp crayfish Procambarus clarkii?

Current Zoology, 2011
Procambarus clarkii is native to the south-central United States (Louisiana) and northeastern Mexico, and is a highly efficient predator that poses a damager to native species after its introduction or invasion. In its natural habitat, P.
