Embodiment 1

[0036] A certain farmer selects a shrimp pond of 2000 square meters according to the requirements of the present invention to carry out intensive cultivation of shrimp species:

[0037] (1) carry out drying pond by the method for the present invention.

[0038] (2) Drain 60 centimeters of water, use 15 kilograms of bleaching powder (available chlorine content is more than 30%) per 667 square meters, kill wild fish and other harmful organisms in the pond.

[0039] (3) Evenly place 20 shrimp nests made of tea tree branches every 667 square meters.

[0040] (4) Seven days after clearing the pond, apply 150 kg of decomposed and fermented pig manure per 667 square meters to cultivate plankton. Mix the fertilizer with EM or spores (according to the instruction manual) and stack them in the shallow water at the four corners of the pond, all below the water surface.

[0041] (5) On April 2, 40 kilograms of prawns were released for every 667 square meters. The male to female ratio o...

Embodiment 2

[0048] A certain breeding farm selects the shrimp pond of 3000 square meters according to the requirements of the present invention to carry out the intensive cultivation of kind of shrimp:

[0049] (1) carry out drying pond by the method for the present invention.

[0050] (2) Drain 65 centimeters of water and use 90 kilograms of quicklime per 667 square meters to kill wild fish and other harmful organisms in the pond.

[0051] (3) 22 shrimp nests made of tea tree branches are evenly placed every 667 square meters.

[0052] (4) 10 days after clearing the pond, apply 170 kg of decomposed and fermented pig manure per 667 square meters to cultivate plankton. Mix the fertilizer with EM or spores (according to the instruction manual) and stack them in the shallow water at the four corners of the pond, all below the water surface.

[0053] (5) On March 31, 38 kilograms of prawns were released for every 667 square meters. The male to female ratio of species of shrimp is 4:1.

Embodiment 3

[0060] A certain breeding company selects the shrimp pond of 3700 square meters according to the requirements of the present invention to carry out the intensive cultivation of the shrimp:

[0061] (1) carry out drying pond by the method for the present invention.

[0062] (2) Drain 70 centimeters of water, and use 100 kilograms of quicklime for every 667 square meters to kill wild fish and other harmful organisms in the pond.

[0063] (3) 25 shrimp nests made of tea tree branches are evenly placed every 667 square meters.

[0064] (4) 10 days after clearing the pond, apply 180 kg of decomposed and fermented chicken manure per 667 square meters to cultivate plankton. Mix the fertilizer with EM or spores (according to the instruction manual) and stack them in the shallow water at the four corners of the pond, all below the water surface.

[0065] (5) Seed prawns were released on April 1, and 36 kg of prawns were released per 667 square meters. The male to female ratio of spe...

Abstract

The invention provides a reinforced cultivating method of freshwater shrimp seedshrimp, which is a reinforced scientific and reasonable cultivating method of freshwater shrimp seedshrimp with low investment and high efficiency in scales through the technologies of selecting seedshrimp in cultivating ponds, building a pond environment, optimizing and regulating water environment, feeding and managing scientifically and the like according to freshwater shrimp aquaculture biology and reproductive biology. The seedshrimp cultivated by the method in the invention can produce shrimp seedlings by over 20% compared with the seedshrimp cultivated by conventional methods under the same seedling conditions. The method in the invention can be used for the large-scale shrimp seedling production of high-quality fresh water shrimp, guarantee smooth promotion of high-quality fresh water shrimp, improve economic efficiency of fresh water cultivation, and improve healthy and sustainable development of fresh water shrimp cultivating industry in China.

Description

technical field [0001] The invention relates to culture biology and reproduction biology of Macrobrachium prawns, in particular to culture biology and reproduction biology of freshwater shrimp, pond environment construction in shrimp breeding, water environment optimization and control, feeding management technology and the like. Background technique [0002] Freshwater shrimp (Macrobrachium nipponense), scientific name Japanese river prawn, commonly known as river shrimp, lake shrimp. Its meat is tender, delicious and nutritious. It is a famous and precious aquatic product loved by the masses. It is also an important freshwater cultured shrimp in my country. Its breeding area ranks first among freshwater cultured shrimps. At present, the annual output of freshwater shrimp farming in my country is more than 200,000 tons, and it is still increasing year by year. However, with the continuous expansion of the breeding scale and the continuous improvement of the degree of inten...
