Embodiment 1

[0020] A culture method for tilapia, comprising the following steps:

[0021] (1) Pond preparation: the pond area is 3 mu, the pond is square, the pond is 2 meters deep, and the bottom of the pond is flat. 10 days before stocking, drain the pond water, add 30 kg of quicklime per mu, 1 kg of metal copper per mu, and 3 kg of pig iron. Disinfect each mu, then add 75 kg of unfermented chicken manure, pig manure, sheep manure, horse manure and other farmyard manure per mu, inject 1.2 meters of water, and put the fish fry after the water turns oily green;

[0022] (2) Fish species stocking: until mid-April, when the temperature rises stably and the water temperature is above 18°C, seedlings are released, and 2000 tilapias with a size of 200 grams per mu are put in;

[0023] (3) Pre-treatment of fish species: use before stocking fish species Wash with the dilution of bleaching powder for 10 minutes, take out the fish species and put them in the tap water for 20 minutes, then put th...

Embodiment 2

[0030] A culture method for tilapia, comprising the following steps:

[0031] (1) Pond preparation: the pond area is 5 mu, the pond is square, the pond depth is 3 meters, and the bottom of the pond is flat. 10 days before stocking, drain the pond water, add 50 kg of quicklime per mu, 2 kg of metal copper per mu, and 5 kg of pig iron. Sterilize per mu, then add 100 kg of unfermented chicken manure, pig manure, sheep manure, horse manure and other farmyard manure per mu, inject 2.2 meters of water, and put the fish fry after the water turns tea green;

[0032] (2) Fish species stocking: until the end of April, when the temperature rises stably and the water temperature is above 18°C, seedlings are released, and 2,500 tilapias with a size of 250 grams per mu are released;

[0033] (3) Pre-treatment of fish fingerlings: before stocking fish fingers, wash them with a dilution of 5‰ trichlorfon for 15 minutes, take out the fish fingers and put them in a tap water pool for 30 minutes...

Embodiment 3

[0040] A culture method for tilapia, comprising the following steps:

[0041] (1) Pond preparation: the pond area is 4 mu, the pond is square, the pond is 2.5 meters deep, and the bottom of the pond is flat. 10 days before stocking, drain the pond water, add quicklime 40 kg per mu, metal copper 1.5 kg per mu, and pig iron 4 kg Sterilize per mu, then add unfermented chicken manure, pig manure, sheep manure, horse manure and other farm manure 90 kg per mu, inject 1.5 meters of water, and put the fish fry after the water turns oily green;

[0042] (2) Stocking of fingerlings: until mid-April, when the temperature rises steadily and the water temperature is above 18°C, seedlings are released, and 2200 tilapias with a size of 220 grams per mu are released;

[0043] (3) Pre-treatment of fish species: use before stocking fish species Wash with the copper sulfate dilution for 12 minutes, take out the fish species and put them in the tap water for 25 minutes, then put the fish specie...

Abstract

The invention belongs to the technical field of fish breeding and particularly relates to a tilapia breeding method. The method includes the following steps that firstly, a pond is prepared; secondly, fingerling is put in the pond to be bred; thirdly, the fingerling is processed before being put in the pond to be bred; fourthly, early-stage feeding is conducted; fifthly, middle and later period feeding is conducted; sixthly, water quality is regulated and controlled; seventhly, fish diseases are prevented and treated; eighthly, adult fish is harvested. The tilapia breeding method has the advantages that the tilapia breeding method is easy to implement, the tilapia survival rate is high, growth is fast, each piece of tilapia can be bred to be 1kg or above in about 4-5 months, the number of diseases is small, the bred tilapia is free of mud smell, good in taste and small in content of fat, and the advantages that output is fast, the yield is high and the quality is good are achieved. The breeding method is simple in process and easy to master, apply and popularize, and large-scale breeding can be performed.

Description

【Technical field】 [0001] The invention relates to the technical field of fish farming, in particular to a method for cultivating tilapia. 【Background technique】 [0002] Tilapia, originally refers to a species of fish in the genus Cichlid with Mozambique as the model origin, now it is a general name for a family of fish in the family Cichlidae, collectively known as Tilapia in English, also known as African crucian carp, non-crucian carp, Vietnamese fish, Wu Guoyu, etc., were originally distributed in temperate zones, tropical India and tropical countries. Now it is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and is known as one of the main sources of animal protein in the future. It is native to Africa. , a tropical fish belonging to the cichlid family. Similar to perch, it usually lives in fresh water and can survive in shallow water in lakes, rivers, and ponds. Tilapia has a wide range of food habits, mostly plant-ba...
