The use of cage culture of green shrimp has the advantages of good natural conditions, high survival rate, short breeding cycle, high yield, and rapid yield. In the specific production practice, we should focus on the following technical processes:
1. Net cages and water areas Net cages used for culture of shrimp should be made of untreated mesh cloth woven of polyethylene monofilament. The area of ​​cages should be 80 to 100 square meters, and the height should be 1.3 to 1.5 meters. The bottom and surrounding net walls of the box are made of 24 mesh cloth, installed into open floating type and fixed with relative fixtures. When selecting aquaculture waters, the water level rises and falls are relatively stable, there are scattered aquatic plants, water quality is thin, and dissolved oxygen. High-quality, non-polluting and micro-flowing secluded shelters are preferred.
Second, the stocking and breeding of shrimp and shrimp farming cycle should be from June to July stocking period to the second year in June to capture the end of the last listing. Per square meter of cages can be put between 1000 and 2000 / kg of 100 to 200 juvenile shrimp, stocking shrimp should be selected on cloudy days or in the morning. After the shrimps are put in the box, they can stock no more than 1/4 of their planktonic aquatic plants in the box to facilitate the shading and concealment of the shrimps. The feed of the shrimp is made of high-quality leeches with about 20% of animal feed (such as miscellaneous fish, cocoon, fish meal, etc.), and special grain feeds can also be used. According to the living habits of the shrimp, the feed should be dispersed and fed, and the amount of feed should be 4% to 5% of the total weight of the shrimp, and less feed during the day (accounting for 1/3 of the daily feed), and the feed should be given in the evening. 2/3 of the total amount, the specific amount of bait should also be based on the climate and the growth of shrimp feeding, flexible control, breeding after 2 months to catch large stay small, listed in batches.
On this basis, we should also focus on the characteristics of cage culture, and strive to put seedlings early, put Qimiao, cages should be regularly viewed to prevent predators and escape.
