Problems solved by technology

[0004] Bream, also known as Wuchang fish, is a typical herbivorous fish with rich nutrition, smooth and tender meat, high protein content, rich in trace elements such as copper and phosphorus, and has fast growth rate, strong adaptability, and high yield. High quality is the main source of dietary protein for the general public; therefore, more and more farmers are focusing on bream farming, and the methods of breeding and feed are becoming more and more diversified. The purpose is to reduce the cost of breeding and increase production. The pursuit of high economic benefits has led to the fact that most of the artificially farmed bream are pot-bellied, close to round in shape, high in fat, loose in meat, heavy in muddy smell, and even infected with various pests and bacteria, which cannot satisfy the general consumption Requirements for green ecological aquatic products

Embodiment 1

[0040] A stepwise breeding method of ecological bream includes a seedling cultivation stage and an adult fish cultivation stage.

[0041] Before the seedling cultivation stage, the pond for cultivating the seedlings shall be disinfected by spreading quicklime at 90 kg per mu. After disinfection, plant algae in the pond. The planting area of ​​algae is 40% of the pond area, and then 0.8 meters of water is poured into the pond. Before stocking the bream seedlings to the pond, bathe the bream seedlings with 3% salt water for 15 minutes. While stocking the bream seedlings, the symbiotic fishes are also stocked. The symbiotic fishes are silver carp. The number of fish accounts for 2% of the total number of bream fish. In the seedling cultivation stage, feed the feed three times a day in the morning, middle and late. The feed is composed of the following parts by weight: 20 parts of sand silkworm powder, 20 parts of snail powder, 20 parts of sea rainbow meat, 15 parts of pig kidney ,...

Embodiment 2

[0046] A stepwise breeding method of ecological bream includes a seedling cultivation stage and an adult fish cultivation stage.

[0047] Before the seedling cultivation stage, the pond for cultivating the seedlings shall be disinfected with quicklime at 120 kg per mu. After disinfection, plant algae in the pond. The planting area of ​​algae is 50% of the pond area, and then 1.2 meters of water is poured into the pond. Before stocking the bream seedlings to the pond, bathe the bream seedlings with 5% salt water for 10 minutes. While stocking the bream seedlings, the symbiotic fishes are also stocked. The symbiotic fishes are silver carp and carp. The number of symbiotic fish accounted for 3.5% of the total number of bream. In the seedling cultivation stage, feed three times a day in the morning, middle, and late. The feed is composed of the following raw materials by weight: 18 parts of silkworm powder, 18 parts of snail powder, 18 parts of sea rainbow meat, 12 parts of pig kidn...

Embodiment 3

[0052] A stepwise breeding method of ecological bream includes a seedling cultivation stage and an adult fish cultivation stage.

[0053] Before the seedling cultivation stage, the pond for cultivating the seedlings shall be disinfected with quicklime at 105 kg per mu. After disinfection, plant algae in the pond. The planting area of ​​algae is 45% of the pond area, and then 1 meter of water is poured into the pond. Before stocking the bream seedlings to the pond, bathe the bream seedlings with 4% salt water for 12.5 minutes. While stocking the bream seedlings, the symbiotic fishes are also stocked. The symbiotic fishes are silver carp, carp and crucian carp, The number of stocked symbiotic fish accounts for 5% of the total number of breams. In the seedling cultivation stage, feed three times a day in the morning, middle, and late. The feed is composed of the following raw materials by weight: 15 parts of sand silkworm powder, 15 parts of snail powder, 15 parts of sea rainbow me...

Abstract

The invention relates to the technical field of aquaculture and in particular to a staged culture method for biological parabramis pekinensis. The staged culture method comprises a fry cultivation stage and an adult fish culturing stage; at the fry cultivation stage, young parabramis pekinensis is put into a pond close to an ecological lake for cultivating, and is fed with feed; at the adult fish culturing stage, the parabramis pekinensis is put in the ecological lake for cultivation and is fed with forage grass. By means of a scientific culture method, obtained parabramis pekinensis is green and ecological, and economic benefits of culture are improved.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of aquaculture, in particular to a stepwise breeding method of ecological bream. [0003] 【Background technique】 [0004] Bream, also known as Wuchang fish, is a typical herbivorous fish with rich nutrition, smooth and tender meat, high protein content, rich in trace elements such as copper and phosphorus, and has a fast growth rate, strong adaptability, and yield The high characteristic is the main source of edible protein for the common people; therefore, more and more farmers are focusing on bream breeding. The breeding methods and feeds are becoming more diversified. The purpose is to reduce breeding costs and increase production. The pursuit of high economic benefits has led to the fact that most of the artificially farmed breams are big belly-shaped, close to a round shape, high fat content, loose meat, heavy muddy smell, and even infected with various pests and bacteria, which cannot satisfy the gen...
