Mariculture Is Mass-produced in Four Seasons

Mariculture is mass-produced in four seasons

Craving mariculture, meaty white shrimp? There is no need to shop online for overseas mail, let alone go to the seaside, Wuhan's own energy production. East and West Lake District Agriculture and rural Bureau revealed that the construction of the agricultural development and investment group of the factory circulating water South American white shrimp breeding base phase I has been put into production, and wait for more than a month, the first products can be listed.

"We released the first batch of shrimp seedlings in January this year and they are growing well. It is estimated that more than 40,000 jin of prawn will be sold in mid-to-late March. Base director Xu Rong introduced that the whole industrial recirculating aquaculture base is constructed in two phases, including the main production facilities such as standard seedling pond, shrimp pond, water treatment system, as well as laboratories, laboratories, testing rooms and other supporting facilities and related living areas. After completion of the project as a whole, it will become one of the largest "land seafood cultivation" bases in our province.

Into the indoor breeding factory, Changjiang Daily reporter saw a number of square pools, the water in the pool is clear, prawn is swimming in groups. The ponds are divided into "standard seedling ponds" and "shrimp ponds," according to the staff. "The 8-meter-long square is the" standard seedling ponds, "and the interior area is about 56 square meters, which is the ponds for breeding young shrimp. We put the young shrimp into a six-meter-long shrimp pond and feed them for a while before they are released into the market.

"The white prawn is a seawater shrimp, which has a fast growth rate, high farmed yield and high protein content. But it's difficult to grow them indoors, and the most important thing is water." Xu Rong said, in terms of water temperature, the suitable water temperature for prawn farming is 28℃ - 30℃.

Previously, in our province, the traditional freshwater fish pond aquaculture of South American white shrimp, limited by temperature and water quality, the most productive two crops a year, and the use of indoor factory circulating aquaculture, due to controllable conditions, a year can produce 6-8 crops, shrimp in the market all the year round, per mu yield is more than ten times of the ordinary open fish pond farming. At the same time, in order to effectively ensure the temperature of breeding water, the base takes advantage of the connection between the local and Hanchuan power plant pipelines to collect "waste heat" from the power plant and heat the water in winter, thus achieving energy saving and consumption reduction.

"One is water temperature, the other is water quality." According to Xu Rong, the sea water for breeding prawns at the base comes from the East China Sea. The sea water is concentrated locally, processed into brine with higher salt, and then shipped to the breeding base for dilution. Shrimp meat is firmer thanks to mariculture.
