The role of vitamin E in polyunsaturated fatty acid synthesis and alleviating endoplasmic reticulum stress in sub-adult grass carp ().

Vitamin E (VE) is an essential lipid-soluble vitamin that improves the fish flesh quality. However, the underlying molecular mechanisms remain unclear. This study aimed to investigate the effects of VE on growth performance and flesh quality in sub-adult grass carp ().

Emerging role of vitamin D in alleviating intestinal structure injury caused by in grass carp ().

Bacterial pathogens destroy the structural integrity of functional organs in fish, leading to severe challenges in the aquaculture industry. Vitamin D (VD) prevents bacterial infections and strengthens immune system function via vitamin D receptor (VDR). However, the correlation between VD/VDR and the structural integrity of functional organs remains unclarified.
