The Red Gold of Aquaculture: The Dual Role of Astaxanthin in Aquatic Nutrition and Human Health

Aquaculture Research, Volume 2025, Issue 1, 2025.
Astaxanthin, a potent keto‐carotenoid, has emerged as a critical bioactive compound in aquaculture and human health. This review synthesizes current knowledge on astaxanthin’s multifunctional roles, spanning pigmentation enhancement, growth promotion, stress resilience, and disease resistance in farmed aquatic species.

Mutual interaction of salinity and dietary protein level on growth, survival and body composition of narrow clawed cray fish (Astacus leptodactylus) [PDF]

, 2012
In this study Astacus leptodactylus were tested for 8 week with three practical diets containing three crude protein (30, 35 and 40%) and isoenergetic level (370kcal/100 g) in fresh water and brackish water of Caspian Sea. In this test, 6 treatments were

Onion Powder and Probiotics Synergistically Improve Growth Performance and Immune Response in Stinging Catfish

Aquaculture Research, Volume 2025, Issue 1, 2025.
Given the rising concerns about antibiotic resistance in aquaculture, the increasing need for sustainable, eco‐friendly alternatives has been highlighted. In response, a 45‐day feeding trial was conducted to evaluate the efficacy of dietary onion powder and probiotics as natural growth promoters and immune enhancers in stinging catfish (Heteropneustes ...

Study on the Artificial Incubation of Procambarus clarkii Embryos

Aquaculture Research, Volume 2025, Issue 1, 2025.
The Procambarus clarkii industry currently faces four major challenges: genetic degradation, disease, unstable prices, and limited breeding methods and modes. Studies on the artificial incubation of P. clarkii embryos can help solve these problems. The purpose of this study was to screen for parameters (disinfectants, embryo stripping stage, embryo ...

The sublethal effects of (2,4-Dichlorophenoxy) acetic acid (2,4-D) on narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823) [PDF]

Archives of Industrial Hygiene and Toxicology, 2016
Abstract2,4-D is a widely used phenoxy herbicide, potentially toxic to humans and biota. The objective of the present study was to reveal short term sublethal effects of 2,4-D on narrow-clawed freshwater crayfish (Astacus leptodactylus Eschscholtz, 1823), based on histology, total haemocyte counts, selected haemolymph parameters, and oxidative stress ...

Effects of Dietary Indian Sphagnum junghuhnianum Peat Moss Pectin on Growth, Digestive Enzymes, Antioxidant Capacity, Immune Responses, and Disease Resistance in Catla catla Fingerlings

Aquaculture Research, Volume 2025, Issue 1, 2025.
In this study, the effects of dietary supplementation of Indian Sphagnum junghuhnianum peat moss pectin were evaluated in Catla catla fingerlings. A total of 375 fish (10.47 ± 0.2 g) were randomly divided (n = 25/tank) into basal diet (Sphagnum peat moss pectin [SPMP] at 0% control) (crude protein: 37%, crude fat: 8%) or four treatment diets, 2% (SPMP2)

Morphology of the narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823) in the north-west Croatia [PDF]

, 2017
Astacus leptodactylus jedna je od četiri nativne vrste porodice Astacidae u Hrvatskoj, ujedno je i ključna vrsta u slatkovodnim ekosustavima. Unatoč važnosti vrste A. leptodactylus, općenito nedostaju podaci o toj vrsti na europskom nivou.

An Improved Crayfish Algorithm‐Based Neural Network Method for Modeling Microstrip Patch Antennas

International Journal of Antennas and Propagation, Volume 2025, Issue 1, 2025.
Artificial neural networks (ANNs) have shown remarkable advantages in antenna modeling and optimization as surrogate models. However, in single‐objective modeling, the convergence accuracy of ANN‐based antenna models is often insufficient. This paper proposes an improved crayfish optimization algorithm (ICOA) to optimize the initial weights and biases ...

MCOA: A Multistrategy Collaborative Enhanced Crayfish Optimization Algorithm for Engineering Design and UAV Path Planning

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
The crayfish optimization algorithm (COA) is a recent bionic optimization technique that mimics the summer sheltering, foraging, and competitive behaviors of crayfish. Although COA has outperformed some classical metaheuristic (MH) algorithms in preliminary studies, it still manifests the shortcomings of falling into local optimal stagnation, slow ...
