Embodiment 1

[0028] The present embodiment provides a method for raising fish in rice fields, comprising the following steps:

[0029] (1) Selection of paddy fields: Select a contiguous paddy field with an area of ​​50 mu with good water quality, no pollution, convenient drainage and irrigation, no flood intrusion in previous years, and deep plowing layer;

[0030] (2) Planning of the paddy fields: Heighten the ridges to 40 cm. The ridges should be pounded tightly to prevent fish from collapsing and leaking; The width is 40 cm, and the depth of the ditch is 30 cm. The fish pit is located at the edge of the field and the corner of the field near the water inlet. The depth is required to be 100 cm, and the area is 5 square meters. There are anti-escape nets all around, and anti-escape nets are installed at the inlet and outlet of the rice field. The anti-escape nets are woven with iron wire. The mesh holes depend on the size of the fish species. Width and height are determined by the width ...

Embodiment 2

[0037] A method for raising fish in a paddy field, comprising the following steps:

[0038] (1) Selection of paddy fields: Select a contiguous paddy field with an area of ​​100 mu with good water quality, no pollution, convenient drainage and irrigation, no flood intrusion in previous years, and deep plowing layer;

[0039](2) Planning of paddy fields: Heighten the ridges to 60 cm. The ridges should be pounded tightly to prevent fish from collapsing and leaking; The width is 50 cm, the ditch is 40 cm deep, and the fish pit is set in the center of the field. The required depth is 130 cm, and the area is 7 square meters. The inlet and outlet of the paddy fields are equipped with anti-escape nets. The anti-escape nets are made of bamboo. The width of the water outlet depends on the height of the ridge. The bottom is buried in soil and reinforced, and then some fir branches and leaves are inserted, which is safer and more reliable;

[0040] (3) Preparation before stocking: Drain...

Abstract

The invention discloses a fish farming method in a paddy field. The method comprises the steps of paddy field selection and planning, preparation before fish fry stocking, fish fry stocking, breeding management, daily management, fishing and other aspects, wherein every aspect is controlled strictly so as to integrally improve the utilization rate of ecological resources, reduce economic costs and increase the yields of rice and fishes. Besides, according to the fish farming method in a paddy field, during the selection of fish fry baits, multiple nutrient materials are specially added, wherein polygonum multiflorum, radix glycyrrhizae, mulberry leaf and other materials can have health care effects on the physique of fish fry, improve the survival rate of the fish fry, and reinforce the disease resistance of the fish fry. Compared with a traditional paddy field fish farming method, the fish farming method in a paddy field is obviously preferred in improving the survival rates of the fish fry and the rice.

Description

technical field [0001] The invention relates to the technical field of ecological aquaculture, in particular to a method for raising fish in rice fields. Background technique [0002] Fish is a temperature-changing vertebrate that lives in water all year round, breathes with gills, and assists body balance and movement with fins. Fish meat is rich in animal protein and phosphorus, rich in nutrition, delicious in taste, easy to be digested and absorbed by the human body, and plays an important role in the development of human physical strength and intelligence. Other parts of the fish body can be made into cod liver oil, isinglass, fish meal, etc. my country has a long coastline, numerous rivers and lakes, and a rich variety of fish. According to surveys, there are more than 1,000 species of freshwater fish in my country, and the famous "four major carp" (herring, grass carp, silver carp, and bighead carp), carp, and crucian carp are the main high-quality freshwater fish sp...
