Embodiment Construction

[0047] A high-efficiency ecological breeding method for Macrobrachium rosenbergii is characterized in that it comprises the following steps:

[0048] (1) Cultivation of juvenile shrimp

[0049] Carry out intermediate cultivation of juvenile shrimp to shrimp seedlings first:

[0050] ① Cultivation pond: Dig a rectangular earthen pond in the cultivation pond, the area is 5%-8% of the total area of ​​the cultivation pond, the width does not exceed 8 meters, the depth is 1.2-1.3 meters, and the top is covered with plastic film;

[0051] ②Cleaning and disinfection of the cultivation pool: Drain the pool water, remove wild debris, and thoroughly dry the bottom of the pool for 1-2 weeks to achieve the purpose of eliminating predators and sterilization; disinfection drugs: bleaching powder 10 grams per square meter or quicklime per square meter 50 grams, mixed with water and sprinkled in the whole pond; 3-4 days after disinfection, plant aquatic plants at the bottom of the cultivatio...

Abstract

The invention discloses an efficient ecological breeding method of giant freshwater prawns. The efficient ecological breeding method includes steps of juvenile prawn breeding, preparation before breeding outside, control of various factors in a pond, outside breeding of shrimps, feeding, nourishing, water quality adjustment and fishing and the like. The shrimps are bred in a greenhouse and put into the pond when growing to juvenile prawns 4-6 in length, so that survival rate is high, breeding period is prolonged, giant prawns are large, yield is high, and breeding efficiency is high.

Description

technical field [0001] The invention relates to a method for cultivating Macrobrachium rosenbergii. Background technique [0002] The traditional culture method of Macrobrachium rosenbergii is to directly put the seedlings into the big pond for culture when the water temperature is above 20°C. The survival rate is low, the culture cycle is short, the size of the adult shrimp is small, the yield is low, and the economic benefit is poor. Contents of the invention [0003] The purpose of the present invention is to provide a high-survival rate, easy-to-operate macrobrachium rosenbergii high-efficiency ecological breeding method. [0004] Technical solution of the present invention is: [0005] A high-efficiency ecological breeding method for Macrobrachium rosenbergii is characterized in that it comprises the following steps: [0006] (1) Cultivation of juvenile shrimp [0007] Carry out intermediate cultivation of juvenile shrimp to shrimp seedlings first: [0008] ① Cult...
