Problems solved by technology

[0004] Sea bass is rich in protein, fat, carbohydrates and other nutrients, and also contains vitamin B2, niacin and trace amounts of vitamin B1, phosphorus, iron and other substances, and has the characteristics of fast growth, strong adaptability and high yield. It is a delicacy loved by ordinary people; therefore, more and more farmers are focusing on seabass farming, and the breeding methods and feeds are becoming more and more diversified. Most of the cultured perch are pot-bellied, elliptical in shape, high in fat, loose in flesh, heavy in muddy smell, and even infected with various pests and bacteria, which cannot meet the requirements of consumers for green ecological aquatic products

Embodiment 1

[0038] The invention relates to a method for cultivating perch, which comprises a seedling cultivating stage and an adult fish cultivating stage.

[0039] Before the seedling cultivation stage, the ponds where the seedlings are cultivated are disinfected by sprinkling quicklime at 90 kg per mu. After disinfection, plant algae in the pond, the planting area of ​​the algae is 40% of the pond area, and then inject 0.8 meters of water into the pond. Before the perch seedlings are stocked in the pond, the perch seedlings are bathed in 3% salt water for 15 minutes with the concentration of substances. When the perch seedlings are stocked, the symbiotic fish are also put in a suitable place. The number of fish accounts for 5% of the total number of perch. In the seedling cultivation stage, the feed is fed three times a day in the morning, middle and evening. The feed is composed of the following raw materials in parts by weight: 20 parts of fish meal, 20 parts of shrimp shell powder...

Embodiment 2

[0044] The invention relates to a method for cultivating perch, which comprises a seedling cultivating stage and an adult fish cultivating stage.

[0045] Before the seedling cultivation stage, the ponds where the seedlings are cultivated are disinfected by sprinkling quicklime at 120 kg per mu. After disinfection, plant algae in the pond, the planting area of ​​the algae is 50% of the pond area, and then inject 1.2 meters of water into the pond. Before the perch seedlings are stocked in the pond, the perch seedlings are bathed in 5% salt water for 10 minutes with the substance concentration. When the perch seedlings are put in a suitable place, the symbiotic fish are also put in a suitable place. The number of sea bass accounts for 4% of the total number of sea bass. In the seedling cultivation stage, the feed is fed three times a day in the morning, middle and evening. The feed is composed of the following raw materials in parts by weight: 18 parts of fish meal, 18 parts of...

Embodiment 3

[0050] The invention relates to a method for cultivating perch, which comprises a seedling cultivating stage and an adult fish cultivating stage.

[0051] Before the seedling cultivation stage, the pond where the seedlings are cultivated shall be disinfected by sprinkling quicklime at 105 kg per mu. After disinfection, plant algae in the pond, the planting area of ​​the algae is 45% of the area of ​​the pond, and then inject 1 meter of water into the pond. Before the perch seedlings are stocked in the pond, the perch seedlings are bathed in 4% salt water for 12.5 minutes with the concentration of substances. When the perch seedlings are stocked, symbiotic fish are also stocked. 3% of the total number of sea bass. In the seedling cultivation stage, the feed is fed three times a day in the morning, middle and evening. The feed is composed of the following raw materials in parts by weight: 15 parts of fish meal, 15 parts of shrimp shell powder, 15 parts of screw meat, 10 parts o...

Abstract

The invention relates to the technical field of aquaculture, in particular to a bass culturing method. The bass culturing method comprises a fry cultivating stage, wherein bass fries are put into a pond near an ecological lake to be cultivated and fed on feed; an adult bass culturing stage, wherein bass is put into the ecological lake to be cultured and fed on small living fishes and forage grass. According to the scientific culturing method, the obtained bass is green and ecological, and the economic benefit of culturing is increased.
