Strong adaptability, the water temperature can survive in the range of 2 ~ 35 C, and the water temperature can also survive at-3 C. The tolerance to hypoxia is poor, and when it is lower than 1mg/l, it will die of hypoxia. The content of protein is not high, and it can be ingested by dead, live, fresh and rotten animal and plant feed or organic debris. Small fish, shrimp, bean cake, rapeseed cake, rice bran and low-grade granular feed can be fed. It usually takes only 2 ~ 3 months to grow to more than 5 cm, and the production cycle is short, and it can be caught and cultured many times a year.
In Rudong and Qidong areas of Nantong, there are many breeding modes, in which Portunus trituberculatus is mainly cultivated with small white shrimps, with a small pond mouth area of 5- 15 mu. There are ring ditches and bantian ponds, which are similar to freshwater crab ponds. The breeding starts from the end of June to 1 1 month, and 3-5 kg of brood shrimps are released. The benefit per mu is about 5000- 1000.
It is not difficult to breed white shrimp, but it has something in common with freshwater Macrobrachium nipponense (green shrimp and river shrimp), which can be used as a reference, unlike Nanmeibai, which has serious bacterial diseases and virus diseases. Mainly afraid of hypoxia, usually pay attention to fertilizer and water, fertilizer and water products account for a high proportion of the total dosage, strengthen the improvement of the bottom material, make good use of microbial agents: photosynthetic bacteria, compound lactic acid bacteria, etc. to adjust the water quality and keep the water quality stable in stages; It is a technical activity to control the outbreak of cyanobacteria by photosynthetic bacteria in high temperature period, which may be related to the salinity of local ponds.
In fact, the trick of breeding depends on the characteristics of its own tangkou. Different soil and water sources have a great influence on daily management. Finding the skills suitable for its own tangkou is far better than learning from others' tendentious tricks!
