Effects of Rhodotorula mucilaginosa on Growth, Antioxidant, and Immune Function, and Toll/Imd and JAK‐STAT Signaling Pathways in Red Claw Crayfish (Cherax quadricanatus)

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
In aquaculture, the use of probiotics to improve growth, immunity, and stress resistance in crustaceans has gained increasing attention. This study examined the effects of incorporating different levels of Rhodotorula mucilaginosa (0.0, 0.1, 1.0, and 10.0 g/kg) into the diet on growth performance, antioxidant capacity (AOC), immune function, Toll/Imd ...

Exploring the Coexposure Effects of Pyrogallol and Microplastic on the Red Swamp Crayfish Procambarus clarkii

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Investigating the impact of two or more toxic chemicals on aquatic organisms is one of the main objectives of toxicological research. Microplastics (MPs) are identified as a carrier or vector for other pollutants. Therefore, the current study investigated the effects of both pyrogallol (PG) and MPs, individually and in combination, on freshwater ...

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

open access: yesAquaculture 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.

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

open access: yesAquaculture 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

open access: yesAquaculture 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 ...

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

open access: yesAquaculture 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)
