Ornamental fish production, like all other segments of aquaculture, relies heavily on the successful spawning, hatching, and survival of larvae. Little is known about the nutrient requirements of most ornamental fish species. In many cultivars of fishes, such as Ornamental fish, especially in those new Ornamental fish species introduced to the aquaculture industry, the rate of fecundity is an important factor in the mass production of young fish and its final selection. Normally, improving the quality of feed used by breeders not only improves the quality of eggs and sperm, but also increases egg production. Gonadal development and fecundity are influenced by some of the nutrients present in the diet and are well documented in frequent spawning of broodstocks and short-term vitellogenic periods. The combination of lipids and fatty acids is one of the main determinants of the reproductive success of reproductive of Ornamental fish and the survival of the offspring. The presence of fats in the diet as a source of energy and essential fatty acids, sterols and phospholipids are considered as carriers of fat-soluble vitamins and are of considerable importance.
