Problems solved by technology

Among them, the nutritional value and economic value of freshwater shrimp are very high, so the breeding of freshwater shrimp has become the choice of synergistic farming. However, the black-tailed red prawn likes to eat shrimp, which greatly reduces the survival rate of green shrimp.
In addition, this nesting breeding method leads to an increase in breeding density, coupled with feeding artificial feed, which together makes it difficult to control the water quality in the breeding pond.

Embodiment 1

[0033] Below in conjunction with accompanying drawing, ecological floating bed described in the present invention is described:

[0034]The ecological floating bed described in the present invention includes an annular support frame 10 floating on the water surface, the bottom of the support frame 10 is provided with an isolation mesh 13, and several cylinders above the isolation mesh 13 are fixed in the support frame 10 20. The cylinder body 20 is arranged along the water surface, and the inner cavity of the cylinder body 20 forms an aquatic plant planting area. The cylinder body 20 of the present invention constitutes a planting base supporting the aquatic plants, and the isolation mesh 13 can surround the root system of the aquatic plants to prevent the black-tailed red carp in the breeding pond from ingesting the aquatic plants at will, and the freshwater shrimp can avoid them at the same time. Habitat in the root system surrounded by the isolation mesh 13, avoid being eat...

Embodiment 2

[0041] The culture method of described black-tailed near red bream:

[0042] The first step is to carry out clearing treatment to the culture pond: splash hot lime water on the culture pond where the water has been drained, and make the lime water evenly distributed in the culture pond, then dry the pond for a week, and then irrigate the pond with water Go into the culture pond and be used for cultivating the described red catfish; The lime water is obtained by adding quicklime by water, and the consumption of the quicklime is 70kg / mu.

[0043] In the second step, put in seedlings: at the beginning of December in the first year, put the winter sliced ​​fish fingerlings of the black-tailed red carp into the culture pond, the winter sliced ​​fish fingerlings are 15cm in size, and the amount of feeding is 35kg / mu; In January of two years, put crucian carp seed in described breeding pond and carry out cover raising, and described crucian carp seed specification is 30 / kg, and descr...

Abstract

The invention relates to a method for cultivating the black-tailed red catfish. The technical scheme of the present invention: an ecological floating bed is set in the culture pond of the red-tailed red carp. The ecological floating bed includes an annular support frame floating on the water surface. The ecological floating bed includes an annular support frame floating on the water surface. The bottom of the support frame is provided with an isolation mesh and a support frame A number of cylinders located above the isolation mesh are fixed inside, and the cylinders are arranged along the water surface. Aquatic plants that purify water are planted in the inner cavity of the cylinders. The roots of aquatic plants constitute the habitat and shelter for freshwater shrimp. The cylinder body of the present invention constitutes the planting base supporting the aquatic plants, and the isolation mesh can surround the root system of the aquatic plants, preventing the black-tailed red carp in the breeding pond from ingesting the aquatic plants at will, and at the same time, the freshwater shrimp can avoid inhabiting the isolation mesh. In the root system where they live, avoid being eaten by the black-tailed red carp, which greatly improves the survival rate of green shrimp. Aquatic plants can significantly reduce ammonia nitrogen and nitrite in water, and have a prominent effect on purifying water quality.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating the red-tailed catfish. Background technique [0002] Black-tailed red catfish is a pelagic fish and is carnivorous. In order to make full use of the water body, when black-tailed red catfish is raised, bottom fish will be raised in the breeding pond, such as: crucian carp, yellow catfish, green shrimp . Among them, the nutritional value and economic value of freshwater shrimp are very high, so the breeding of freshwater shrimp has become the choice of synergistic farming. However, the black-tailed red prawn likes to eat shrimp, which greatly reduces the survival rate of green shrimp in nesting. In addition, this nesting breeding method causes the breeding density to increase, and the artificial feed is fed, which together cause the water quality in the breeding pond to become difficult to control. Contents of the invention [0003] In...
