What nutrients are in fish food? A complete guide
What nutrients are in fish food?
The nutritional needs of ornamental fish mainly fall into five categories: protein, fat, carbohydrates, vitamins and inorganic salts.
As for the need for protein, because it is affected by factors such as the type of protein in the food and the growth and development stage of the ornamental fish, the optimal protein content in food for ornamental fish is a very complex issue. The nutritional value of different proteins varies greatly due to differences in amino acid composition and degree of digestibility. Fat mainly provides energy, spares protein, and is also a carrier of fat-soluble vitamins (vitamin A, vitamin D, vitamin E, vitamin K), and promotes the absorption and utilization of these vitamins. Therefore, fat must be added when processing food. Carbohydrates mainly serve as an energy source, have the function of sparing protein, and participate in forming fish body tissues. The content of vitamins and inorganic salts in food is relatively small, but they are indispensable. Vitamins are a class of biologically active substances necessary for maintaining the normal physiological functions of ornamental fish, and they play an important role in maintaining normal growth and development of the fish and improving disease resistance. The vast majority of vitamins are basic components of enzymes and participate in regulating metabolism in the body. Vitamins generally cannot be synthesized in the body and must be supplied by food. If a certain vitamin is lacking, it will lead to metabolic disorders, body imbalance, and stunted growth, and in severe cases cause death. To supplement vitamins, multivitamin preparations can be added to the food, and a certain amount of live food can be fed to meet the vitamin needs of ornamental fish. Among food components, inorganic salts constitute bones and other cellular tissues, participate in the regulation of body fluid osmotic pressure and hydrogen ion concentration, and are components or catalysts of the enzyme system in ornamental fish. Inorganic salts account for a relatively large proportion of the body composition of ornamental fish, about 21.17%. If certain inorganic salts are lacking in the food, ornamental fish will develop metabolic disorders or deficiency diseases. Therefore, when designing food formulas, adding meat and bone meal, mixed inorganic salts, etc. has a promoting effect on the growth of ornamental fish.
