Vitamin C is the most important nutrient in aqua feeds due to its potential antioxidant and immune stimulant characteristic features. Vitamin C is not biologically synthesised in aquatic organisms, therefore it needs to be supplied through food, so that fish or shrimp maintain their health status at normal condition.This particular nutrient component holds the fish and shrimp body cells together through collagen synthesis. Collagen is a connective tissue that holds muscles, bones and other tissues together. Collagen is also needed for the healing of wounds, bone and tooth formation, moulting, release of stress and toxic gases, strengthening blood vessel walls, improves immune function, increasing absorption and utilization of iron and acting as an antioxidant.Vitamin C works with vitamin E and plays a crucial role in antioxidant properties by neutralizing free radicals throughout the body.
