Problems solved by technology

[0002] Tilapia has the characteristics of strong reproduction, fast growth, high yield, and strong disease resistance. As a farming species recommended by the Food and Agriculture Organization of the United Nations, it has become one of the most widely farmed species in the world and is farmed in more than 100 countries and regions. At the same time, it is recognized as a healthy food because of its thick meat, few bony spurs, easy processing and preservation, and rich in various unsaturated fatty acids. Its global consumption is on the rise; but in recent years, with the continuous expansion of high-density breeding The aquaculture environment continues to deteriorate, stress factors increase, and the fish's disease resistance decreases, resulting in frequent tilapia diseases and low feed absorption and conversion efficiency, which makes the synthesis and accumulation of tilapia nutrients unsatisfactory, and makes tilapia Slow growth has brought huge economic losses to the tilapia aquaculture industry; high economic benefit

Abstract

The invention belongs to the technical field of tilapia breeding, and particularly relates to a breeding method of improving the tilapia nutritional quality. The method particularly comprises the following steps that 1, feed for tilapia is used for feeding three times a day, the total daily feeding amount is 1.7-1.8% of the weight of the tilapia, the feed accounting for 25% of the total daily feeding amount is used for feeding at 6:00, the feed accounting for 20% of the total daily feeding amount is used for feeding at 14:00, and the feed accounting for 55% of the total daily feeding amount isused for feeding at 19:00, wherein the feed for tilapia is prepared from crab shell powder, fresh purple sweet potato vines, fresh hawthorn fruits, grape skin residues, oat, corn, fresh paulownia leaves, fresh fig leaves, radix stemona polysaccharide, lycium barbarum polysaccharide and alpinetin; 2, purslane juice is used for sprinkling a tilapia pond once a week. Rapid growth of the tilapia is promoted, the breeding cycle is shortened, diseases are reduced, accumulation of nutrient substances is facilitated, the selenium content, iron content and carotene content of tilapia muscles are increased, and the nutritional quality of the tilapia is greatly improved.
