Culture method for super tilapia in northern area

Abstract

The invention discloses a culture method for super tilapia in the northern area, which includes three steps: pond selection, flowering culture and adult fish culture. The flowering culture step includes the four sub-steps of selecting a flowering pond, putting and growing summer flowers, carrying out feeding and putting fish fries of different sizes into different ponds. The adult fish culture step includes the five sub-steps of pond cleaning and disinfection, fish fry throwing, daily management, adult fish transfer and disease prevention and control. The overwintering problem in the culture of super tilapia in the northern area is solved, and the difficulty in breeding fish fries is solved. An excellent living environment is provided for adult fish breeding, and the survival rate of fishfries is improved. The floating feed used has a strong protective effect on the water quality, and does not pollute water. The utilization rate of feed is high, and fish fries grow fast.

Description

technical field

[0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating super tilapia in the northern region. Background technique

[0002] Tilapia, commonly known as: African crucian carp, non-crucian carp, Vietnamese fish, Nanyang crucian carp, etc. Originally refers to the species of Oreochromis mossambicus with Mozambique as the model place of origin: Mozambique Oreochromis mossambicus (scientific name: Oreochromis mossambicus), now it is the genera of Oreochromis and Oreochromis mossambicus in the family Cichlidae. The common common name; in English, it is collectively called Tilapia. Now it is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and it is known as one of the main sources of animal protein in the future. It usually lives in fresh water, and can also live in salt water with different salinity. It survives in the shallow water of lakes, rivers, and ponds...

Embodiment 1

[0024] A culture method of super tilapia in the northern region, comprising the steps of:

[0025] Step 1. Pond selection: The pond is surrounded by waterproof plastic film, and the bottom of the pond is compacted with three-grade lime soil. The area of ​​the pond varies from 1 mu to 1 meter deep. The water source of the pond is underground deep well water. The value of 6.5 is convenient for water intake and drainage, and the pond is equipped with an aerator;

[0026] Step 2, flower cultivation:

[0027] (1) Selection of the flower pool: the area of ​​the flower pool is 300m 2 , the top of the pool is covered with a light-transmitting plastic film like a vegetable shed. There is a water circulation device in the pool. One end of the pool is equipped with a water source inlet, and the other end of the pool is equipped with a water source outlet. Type aerator, disinfect the bottom of the pool with quicklime before releasing water, keep the temperature in the shed above 20°C, a...
