[0002] Existing fish farming methods are single fish species farming, and a large part of artificially fed feed will not be fully utilized and cause water pollution. After the water quality in the fish pond deteriorates, the aquaculture industry always directly discharges this part of the sewage and then introduces fresh water, in this way to maintain the balance in the aquaculture system. This traditional fish farming method has a negative impact on the ecological environment of the water a certain amount of pressure

Embodiment 1
[0025] A grass carp breeding method includes the following steps:
[0026] a. Before the fry stocking, the fish pond shall be cleaned and disinfected, and 10-20 kg of quicklime shall be used per mu.
[0027] Fill the fish pond with water, and filter the water inlet with 40-60 mesh gauze when filling.
[0028] After one week of water injection, the grass carp summer flowers and silver carp summer flowers were stocked at a ratio of 5:1. The stocking amount of grass carp summer flowers was 5000 / mu, and the stocking amount of silver carp summer flowers was 1000 / mu.
[0029] Shrimp and snails are stocked in fish ponds. In this embodiment, blue prawns and snails are used, the stocking amount of blue snails is 1.5 kg / mu, and the stocking amount of snails is 3 kg / mu;
[0030] e. Feed the fry a floating pellet feed with a protein content of 35% to 38%;
[0031] f. Carry out normal disease prevention and control, according to the water quality of the fish pond, use quicklime to control the ...

Abstract
The invention discloses a fish culturing method, which includes steps: a, clearing and disinfecting a fish pond before putting fry into the pond to breed; b, injecting water into the fish pond; c, putting the fry into the fish pond to breed one week after water injection, wherein the fry include one type of fry and white carp summerlings and another type of fry and white carp summerlings, which are put to breed according to a proportion of 5:1 to 4:1; d, putting shrimps and snails into the fish pond to breed; e, feeding the fry with fodder having 35%-38% of protein; f, using quicklime 10-20kg per mu to control water quality according to conditions of the water in the fish pond; and g, supplying fresh water into the fish pond regularly to guarantee the effective water level of the fish pond. By means of the technical scheme, energy and matters in the whole culturing system are controlled and converted effectively, no culture waste water is generated, and zero emission of culture waste water is realized.
Description
technical field [0001] The invention relates to a herring breeding method, which belongs to the technical field of animal reproduction. Background technique [0002] The existing fish breeding methods are all single fish species. A large part of the feed artificially fed will not be fully utilized and cause water pollution. Many aquaculture operators always discharge it directly after the water quality in the fish pond deteriorates. This part of the sewage is removed, and then fresh water is introduced to maintain the balance in the aquaculture system. This traditional method of fish aquaculture has caused a certain pressure on the ecological environment of the water area. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a fish breeding method. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a fish farming method, comprising the following st...
