Breeding method to improve intestinal immunity of tilapia

Abstract

The invention discloses a cultivation method for improving the intestinal immunity of tilapia, which comprises: setting the depth of the fish pond to 2m, and the depth of the mud at the bottom of the fish pond to 0.5m; arranging several floating beds in the fish pond; The sum of the area is 5-10% of the area of ​​the fish pond; Chinese herbal medicines are planted on several floating beds, including Chinese knotweed, Houttuynia cordata, and mint; some tilapias are put into the fish ponds, and the weight of tilapias is 33g± 5g, the density of tilapia in fish ponds is 50-70 / m 3 ; Put feed several times into the fish pond regularly every day, feed at 8:00 and 16:00 every day in the seedling stage, and the weight of feeding each time is 4.5-6.5% of the total weight of fry; And 16 o'clock put in feed, and the weight of putting in feed every time is 3.5~4.5% of tilapia weight. Such setting is beneficial to improving the intestinal immunity of the tilapia, which in turn is beneficial to increasing the yield of the tilapia.

Description

Breeding method for improving intestinal immunity of tilapia technical field The present invention relates to the culture technical field of tilapia, particularly a kind of culture that improves tilapia intestinal immunity. breeding method. Background technique Tilapia, commonly known as: African crucian carp, Vietnamese fish, South Sea crucian carp etc., it has very strong adaptability, can live in In fresh water, it can also live in salt water with different salinity content. Tilapia is the key scientific research and cultivation of freshwater fish in the world's aquaculture industry. Aquaculture fish is known as one of the main sources of animal protein in the future. In recent years, along with the continuous expansion of high-density breeding scale, the breeding environment continues to deteriorate, and stress factors increase, causing The intestinal immunity of tilapia decreases, which in turn leads to a slowdown in the growth rate of tilapia, which brings e...

Problems solved by technology

[0003] In recent years, with the continuous expansion of high-density farming scale, the breeding environment has been deteriorating and stress factors have increased, resulting in the decline of tilapia's intestinal immunity, which in turn leads to a slowdown in the growth rate of tilapia, which brings economic benefits to farmers. loss
