Abstract

Features such as providing energy, essential fatty acids needed by fish and aid to absorb fat-soluble nutrients have made fat an important influencing factor in aquaculture. Given the increased global consumption of fish oil in aquaculture, it will be difficult to supply it in the future. The inexpensive and easily available alternatives, which do not cause disturbance the growth of fish or fillet quality is the main challenge in the sturgeon feeding process. Vegetable oils are considered as the most noteworthy source of alternative fats in dietary formulations of fish. However, fish needs a certain level of fat, and fat in amounts higher or lower than this desirable level can be a threat to the growth and even the health of the fish. So, it is important to explore the optimal measure of dietary lipid for aquatic animals with high economic value. Hence, due to the biological importance (evolutionary, geographical, morphological, anatomical and physiological) and economic value (environmental, recreational, aquaculture) of sturgeon fish, it is necessary to investigate and research the type and optimal level of dietary lipids. This approach, by introducing different vegetable oils and using them in the nutrition of sturgeon, provides a more realistic understanding of the nutritional needs of these valuable species, which will help to better manage sturgeon stocks and their more sustainable production.
