What water temperature is suitable for river shrimp farming? Detailed explanation of the suitable temperature

SummaryRiver shrimp can survive in water temperatures of 0-40°C, their growth water temperature is 10-30°C, and the most suitable water temperature for their growth is 25-28°C. When the water temperature is above 10°C, river shrimp begin to feed, and their feeding capacity increases as the temperature rises; when the water temperature is below 8°C, their food intake decreases significantly, and if the temperature drops further they will even stop feeding.

River shrimp have strong adaptability to temperature; they can survive in water temperatures of 0-40°C, 10-30°C is their growth water temperature, and 25-28°C is the most suitable water temperature for their growth. When the water temperature is above 10°C, river shrimp begin to eat, and as the water temperature rises, their feeding capacity becomes stronger; when the water temperature is below 8°C, the feeding of river shrimp decreases significantly, and they may even stop feeding.

River shrimp have relatively high requirements for the oxygen content in the water, and their suffocation point is somewhat higher than that of fish. As long as the oxygen content in the water is insufficient, they will show floating-head behavior, and some newly molted soft-shell shrimp may even die.

Notes on river shrimp farming

1. Pond selection: The pond area for river shrimp farming is generally controlled at about 3-5 mu, with a water depth of about 1.5-2.5m,

It requires sufficient freshwater sources, clear and pollution-free water quality, and the pond bottom is best sandy; ponds that have previously been used to farm river shrimp are best.

2. Preparatory work: 7 days before releasing the shrimp fry, stretch a sieve silk net in the pond to filter out impurities, apply base fertilizer in the pond for fertilization, and cultivate sufficient natural bait for river shrimp to feed on. Generally, shrimp fry are released in late May. Before release, first place the shrimp fry in fresh water for one week to adapt. Within one month after release into the pond, the natural bait in the water is enough for them to feed on, and there is no need to feed the shrimp fry; after one month, feed can be given in an appropriate amount.

3. Daily management: 10 days after the shrimp fry are released, begin slowly adding new water to the pond; generally, adding 10-15cm of new water every 7 days is enough. In summer when the temperature is higher, the water should be changed every day. During the farming process, regularly splash a certain proportion of quicklime into the pond for disinfection, improve the water quality and the bottom substrate of the pond, so as to promote the molting and growth of river shrimp.

Market prospects of river shrimp farming

River shrimp are a high-quality shrimp species unique to China and Japan that lives in freshwater. They are mainly distributed in rivers, lakes, reservoirs and ponds across China. At present, the area and output of river shrimp farming in China are second only to river crab.

River shrimp have always been a premium product among China's freshwater shrimp. Their shells are thin and their meat is thick, the meat is tender, and they are rich in nutrients, deeply loved by the public. River shrimp are not only loved by many domestic consumers, but are also an important export product of China. Both domestic and international markets are in short supply, so the market prospects for river shrimp farming are still quite good.
