Continuing global warming intensifies the thermal stress suffered by fish, urgently necessitating effective mitigating techniques. This study aims to investigate the mechanisms by which astaxanthin alleviates oxidative stress and inflammatory damage induced by thermal stress. Under thermal stress, an increase in oxidative stress was observed in the myocytes of Micropterus salmoides , however, intervention of astaxanthin exerte...

An 8-week feeding trial was conducted to assess the effects of different dietary lipid levels on the growth performance, feed utilization, and body composition of juvenile kelp grouper Epinephelus moara. Six diets with varying lipid levels of 2.82%, 5.30%, 7.83%, 11.76%, 14.19%, and 16.32% (designated as CL1 to CL6) were carefully formulated. A cohort of 324 juvenile fish (initial body weight of 5.87 ± 0.09 g fish−1) were rand...

Introduction Screening excellent bacterial strains for fermentation is the key to improving the nutritional value and bioavailability of soybean meal (SBM). This study investigated the application of Bacillus subtilis -fermented soybean meal (FSBM) on the feed of Pacific white shrimp ( Litopenaeus vannamei ). Methods FSBM was used to replace 0%, 25%, 50%, 75%, and 100% fish meal, and the feeding trial was lasted for 8 weeks (i...
