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 ,...

[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...
