Abstract

The invention discloses a breeding method for improving intestinal immunity of tilapia mossambica. The method comprises the following steps that the depth of a fishpond is set to be 2 m, and the depthof sludge at the bottom of the fishpond is set to be 0.5 m; a plurality of floating beds are arranged in the fishpond, wherein the sum of the areas of the floating beds is 5-10% of the area of the fishpond; Chinese herbal medicines are planted on the floating beds, wherein the Chinese herbal medicines comprise polygonum cuspidatum, houttuynia cordata and mint; a plurality of tilapia mossambica isput into the fishpond, wherein the weight of the tilapia mossambica is 33+ / -5 g, and the density of the tilapia mossambica in the fishpond is 50-70 per cubic meter; and feed is put into the fishpondfor several times at regular time every day, the feed is put at 8 o'clock and 16 o'clock every day in the fry stage, wherein the weight of the feed put each time is 4.5-6.5% of the total weight of fry, and in the adult fish stage, the feed is put at 8 o'clock and 16 o'clock every day, wherein the weight of the feed put each time is 3.5-4.5% of the weight of the tilapia mossambica. Due to the arrangement, the intestinal immunity of the tilapia mossambica can be improved, and the yield of the tilapia mossambica can be increased.

Description

technical field [0001] The invention relates to the technical field of tilapia culture, in particular to a culture method for improving intestinal immunity of tilapia. Background technique [0002] Tilapia, commonly known as: African crucian carp, Vietnamese carp, South Sea crucian carp, etc., has strong adaptability and can live in fresh water or salt water with different salinity. Tilapia is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and is known as one of the main sources of animal protein in the future. [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. Contents of the invention [0004] The main purpose of the present inven...
