Antibiotic-free breeding method of tilapia

Abstract

The invention discloses an antibiotic-free breeding method of tilapia, which comprises the following steps of: constructing a breeding pond, putting in fry, and feeding fermented feed until the tilapia is captured. A water body in the breeding pond with an inclination angle of 6 degrees at the bottom can naturally impact and flow under a reflux action of a pump, the tilapia can continuously swim along a water flow to achieve high-density breeding, it can be guaranteed that meat quality of the tilapia is more compact and fresh and tender by continuously swimming along the water flow; the breeding pond is exposed to the sun in advance, and is sterilized and disinfected by quicklime at regular time to guarantee the water quality; and the tilapia eats fermented feed which is not added with anyantibiotics or medicines from fry to adult fish, and a living water body passes through a filter and an ammonia nitrogen-nitrite removing device for circulating treatment, so that particles, impurities and heavy metals in the water body are filtered out, ammonia nitrogen and nitrite in the water body are effectively decomposed, harmful substances such as the ammonia nitrogen, the nitrite, the antibiotics, the heavy metals, toxins, pesticides and the like are not accumulated in the body of the tilapia, and safety of eating is guaranteed.

Description

technical field [0001] The invention relates to an antibiotic-free culture method for tilapia. Background technique [0002] In the traditional tilapia farming process, with the abuse of antibiotics in tilapia feed and treatment, the residues of antibiotics in tilapia are becoming more and more serious, which directly threatens human health, and the method of filtering the cultured water Basically, it is all physical filtration. Although physical filtration can filter out particulate matter and impurities in aquaculture water, ammonia nitrogen and nitrite in the water cannot be filtered out. Ammonia nitrogen and nitrite accumulated in tilapia When the nitrate reaches a certain concentration, tilapia is susceptible to various diseases, even poisoning and death, which directly affects the economic benefits of farmers. Contents of the invention [0003] The object of the present invention is to provide a method for culturing tilapia without antibiotics, to solve at least one...
