Cultivation Technique of Macrobrachium rosenbergii

(1) Cultivation conditions. A small earthen pond dedicated to nurturing young prawn should be constructed. The location where the pool is built should be as far as possible to the sunny and leeward areas and close to where the prawn is grown. The cultivation pool is rectangular and east-west direction, which is good for lighting. The area of ​​each pool is 500 meters. It is advisable to control the water depth by about 1 meter. The pool should be strong, no leakage, strong water retention. The bottom of the pool should have a certain degree of slope, and two simple and easy access and drainage gates should be built to facilitate the adjustment of water quality and water collection. A conical mesh bag made from a 50-mesh sieve is installed at the inlet to prevent fish eggs and other harmful organisms from entering the pool. A barrier made of 40-mesh sieves is set at the outlet to prevent shrimp shrimps from escaping from the pool.
(2) Prepare to plant seedlings. Fifteen days before juveniles are stocked, the nursery must be strictly disinfected. The disinfectant uses quicklime or bleach, the amount of quicklime is 250g/m2, and the amount of bleach used is 150g/m2. During the disinfection, 0.5m deep water is left in the pond. The quicklime or bleaching powder is added into the slurry and dissolved in water to form a slurry. The whole pool is sprayed evenly, and plankton is fertilized and propagated. After the water has a certain degree of fatness, the water level is gradually deepened to about 0.8 meters so that the water remains light green and the transparency is about 35 centimeters.
(3) Stocking density. It is generally required that only 1,000 litres of shrimp should be dewatered out of the soil pool per square meter. If there are aeration facilities or flushing conditions, 2000 to 3000 can be stocked per square meter.
(4) feed feeding. Feeds fed are basically the same as ponds, mainly eggs, with pellets (crushed). Feeding amount: In the initial stage of stocking, 100 thousand grams of eggs are fed every 10,000 shrimps, and the eggs are steamed, kneaded, filtered and fed 3 times. After 3 days, it gradually increased and increased to about 200 grams per 10,000 tails on the 10th day, ie, 10 times in 10 days. After 20 days, the prawn was gradually adapted to the large pool with powder or broken granules of Macrobrachium rosenbergii. After the feed changes.
(5) Water quality management. Before stocking, the influent water is filtered with a 50-mesh sieve to prevent the enemy from entering the pool and the water level is controlled at about 0.7 meters. With the growth of shrimp, gradually deepen to about 0.9 meters. After 7 days of stocking, change the water every 3 days.
