Embodiment 1

[0020] A method for efficiently cultivating Macrobrachium rosenbergii, comprising the following steps:

[0021] (1) Shrimp Pond Cleaning: Choose a number of earthen ponds with a size of 180-200m2 and a depth of 1.8-2m as shrimp ponds. After 7 days of exposure to the sun, spray the shrimp pond with an anti-virus solution mixed with lime powder, 84 disinfectant and water at a ratio of 1:001:30. The spraying dosage is "100ml / m 2 "On the 3rd day after spraying, inject water into the shrimp pond with a water injection height of 30cm. After 10 hours, drain the water and re-inject water. The water injection volume is 20cm. After 5 hours, drain the water; Mosquito killer lamps and sun lamps are set up around the pond base;

[0022] (2) Fertilization of shrimp ponds and planting: Sprinkle fertilizers on the surface of shrimp ponds for fertilization. Fertilizers refer to chicken manure, sheep manure, pig manure, soybean milk dregs, plant ash, coal cinders, eggshells, melon skins, high ...

Embodiment 2

[0032] A method for efficiently cultivating Macrobrachium rosenbergii, comprising the following steps:

[0033] (1) Shrimp pond finishing: the selected size is 180-200m 2 , Multiple earthen ponds with a depth of 1.8-2m are used as shrimp ponds. First drain the water in the earthen ponds, remove large stones, dead branches, plastic bags, household garbage and other debris in the shrimp ponds, and expose them to the sun for 10 days. Days later, the shrimp ponds were sprayed with an anti-virus solution mixed with lime powder, 84 disinfectant and water at a ratio of 1:001:30. The spraying dosage was "120ml / m 2 "On the 3rd day after spraying, inject water into the shrimp pond with a water injection height of 40cm. After 15 hours, drain the water and re-inject water. The water injection volume is 30cm. After 8 hours, drain the water; Mosquito killer lamps and sun lamps are set up around the pond base;

Embodiment 3

[0044] A method for efficiently cultivating Macrobrachium rosenbergii, comprising the following steps:

[0045] (1) Shrimp pond finishing: the selected size is 180-200m 2 , Multiple earthen ponds with a depth of 1.8-2m are used as shrimp ponds. First drain the water in the earthen ponds, remove large stones, dead branches, plastic bags, domestic garbage and other debris in the shrimp ponds, and expose them to the sun for 8 days. Days later, the shrimp ponds were sprayed with an anti-virus solution mixed with lime powder, 84 disinfectant and water at a ratio of 1:001:30. The spraying dosage was "110ml / m 2 ", on the third day after spraying, inject water into the shrimp pond with a water injection height of 35 cm. After 12 hours, drain the water and re-inject water. The water injection volume is 25 cm. After 6.5 hours, drain the water; Mosquito killer lamps and sun lamps are set up around the pond base;

[0046] (2) Fertilization of shrimp ponds and planting: Sprinkle fertiliz...

Abstract

The invention provides an efficient cultivation method for giant freshwater prawns. The method is characterized by comprising the steps of prawn pond cleaning, prawn pond fertilization, plant cultivation, prawn pond water virus killing, young prawn throwing-in and feeding, prawn pond management and prawning; prawn pond surface maintenance and water qualify purification adopt manual work for the salvage and clearing of floating trash and debris on the prawn pond surface and splashing of a mixture composed of medical stones and carbon for the water quality purification, so that a living environment of the prawns is enabled to be clean and sanitary. The efficient cultivation method has the beneficial effects of simple operation, high prawn survival rate guarantee, stable quality, low germ infection probability, rapid growth, low cultivation cost and great economic benefit.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for efficiently cultivating Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii, also known as Malaysian prawn and freshwater long-armed prawn, is a large freshwater prawn native to Southeast Asia. It has the advantages of fast growth, wide appetite, good meat quality and short breeding cycle. Since the 1960s, artificial cultivation of Macrobrachium rosenbergii has developed rapidly, and it is more common to breed this shrimp in Southeast Asian countries and some other regions. Macrobrachium rosenbergii has a thin shell and fat body, fresh and tender meat, delicious taste and rich nutrition. In addition to the flavor of general freshwater shrimp, the mature giant macrobrachium rosenbergii is full of gonads in the head and breastplate, which has a special delicious taste similar to crab roe. . Every 100 grams of shrimp meat contains 20...
