Method for net cage fish culture

Abstract

The invention discloses a method for net cage fish culture. The method includes the following steps that A, the hydrological environment is detected; B, net cages are arranged; C, fingerling is thrown; D, continuous culture is performed. According to the technical scheme, the disease incidence and death rate of the fingerling are reduced in growth environment conversion and transferring processes; the problems that space utilization rate of the net cages is low, and the net cages can not continuously culture fishes are solved.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a method for raising fish in a cage. Background technique [0002] Fish are the oldest vertebrates; they inhabit almost all aquatic environments on Earth—from freshwater lakes and rivers to saltwater seas and oceans; there are two types of fish, freshwater fish and saltwater fish ; In my country's inland areas, freshwater fish are mainly cultured; therefore, freshwater fish has become a food that often appears on dining tables in inland areas; because fish meat is rich in animal protein and phosphorus, it is rich in nutrition, delicious in taste, and easy to eat. Being digested and absorbed by the human body plays an important role in the development of human physical strength and intelligence; therefore, in the Warring States period more than 2,000 years ago, Mencius, a famous thinker, statesman, and educator in my country, said in his writings: "Fish, what we eat Desires, ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is the deficiencies of the prior art; the fish species have been solved because of the transformation of the growth environment and in the process of transshipment, the incidence of disease and the high mortality rate; the space utilization rate of the net cage is low; The problem that the tank cannot continuously raise fish
