Embodiment Construction

[0018] The present invention will be described in further detail below by means of specific embodiments:

[0019] The reference signs in the accompanying drawings of the description include: small net box A1, medium net box 2, and small net box B3.

[0020] A method for raising fish in cages, comprising the steps of:

[0021] Step 1. Hydrological environment detection: the breeding waters are fresh waters, the water depth should be kept above 12m throughout the year, the water flow velocity is 0.05~0.25m / s, the water PH=6.5~9.5, and the dissolved oxygen is greater than 3mg / liter.

[0022] Step 2. Cage layout: as attached figure 1 As shown: the net cage frame is all double steel pipe structure, forming a Chinese character, four middle net cages 2 are arranged in the middle of the net cage frame, and the four middle net cages 2 are arranged clockwise to form a square shape; One side edge of case 2 is provided with four small net cages A1, and four small net cages A1 are arrang...

Abstract

The invention discloses a cage fish culture method which includes the steps: first, hydrological environment detection; second, cage arrangement: arranging four middle cages in the middle of a cage framework, and arraying the four middle cages into the shape of a Chinese character 'tian' along a clockwise direction; arranging four small cages A at the edges of one side of the four middle cages in a linearly separated manner; arranging four small cages B at the edges of the other side of the four middle cages in a linearly separated manner; arranging the middle cages, the small cages A and the small cages B in a common large cage; diagonally arranging the equal-depth cages of the four middle cages; arranging cylindrical connecting meshes among the small cages A, the small cages B and the four middle cages; third, fingerling throwing; fourth, continuous culture. Fishes need different growth spaces at various stages, and different sizes of the small cages A, the small cages B and the middle cages provide the spaces needed by the fishes.

Description

technical field [0001] The invention relates to the field of fishery, in particular 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, bear's paws are w...
