"Posting autumn" is here!Suzhou Wuzhong "Taihu No. 1" shrimp climbed up to the table

In September of Golden Autumn, the climate was pleasant. The river crab was gradually completing the last shelling, supplemented with nutrition, and pasted fat autumn. Prior to the launch of the river crab, the "Taihu No. 1 prawns", which are popular with the general public, has quietly climbed the table of Suzhou citizens.

On September 5th, at the Modern Fishery Park in Linhu, the staff of the Wuzhong District Aquatic Products Technology Promotion Station and the Linhu Agricultural Services Center jointly proofed the Rochena shrimp that was released on May 10 this year. The average weight of more than 75g/piece has reached the listing specifications.

Rochenna Shrimp is a family of long -armed shrimp and marsh shrimp. It mainly uses aquatic insect larvae, small crustaceans and organic debris. It is mainly distributed in Southeast Asian countries such as my country and the Philippines, Cambodia. Breeding in seawater and growing in fresh water.

The reporter learned that in Wuzhong, Rochenna Shrimp is mainly cultivated through the method of raising in river crab breeding. The earliest can be traced back to Taihu Pyramid in 2013. Raising it in Taihu Paper, so the general public passed down, which kindly called it "Taihu No. 1 shrimp."

With the withdrawal of Taihu Biansi.com, the completion of the comprehensive transformation of high -standard ponds has been completed. Since 2020, the Wuzhong District Aquatic Products Technology Promotion Station has begun to promote the Rochen Narura Shrimp Model in the region. Tests formed the "Technical Specifications for Roche Rochen Roche Shrimp Ecological Breeding", which gives guiding opinions on the release time, specifications, density, and breeding technical models of Rochena Shrimp in the river crab pond.

On this basis, the majority of farmers and breeding companies have the courage to explore and actively develop. The rivers crab ponds in the region have been carried out vigorously. At present, there are three main modes of Wuzhong District: river crab+green shrimp+Rochenna shrimp mixing, river crab pond fence breeding Rochennon shrimp and flowing sink fish+vegetable+river crab+Rochena shrimp mode.

The first model is after the river crab breeding pond is cleared, and the crab and green shrimp seedlings are released at the same time. After the sales of the green shrimp at the end of June, the specifications of the Rochenon seedlings with 30-40 pounds in the whole pool 5 -10 catties/mu, the amount of feeding is not increased during the breeding process, so that the Rochennon shrimp uses the bait in the process of feeding in the river crab. It produces 25-30 catties/mu of the Rochennon shrimp. Get more water for water and green.

The second model is to surround the area of ​​about 20%of the area in the river crab pond, and the Rochennon seedlings with 30-40/jin at the end of June are 50-60 catties/mu. The output is generally 150 At about/acres, the sales income is 10,000 yuan/mu. The increase in the output value of the whole pond is about 1500-2000 yuan/mu. This model makes full use of the excellent water quality and waterweed conditions of river crab ponds. At the same time, it has a small impact on river crab breeding. The breeding cycle, low risk, and high efficiency are welcomed by the majority of farmers. Rochena Shrimp Model.

Linhu Modern Fishery Park adopts the third model. The construction area of ​​30 acres of ponds is 1 stream of water tanks of 200 square meters. Material transport to vegetable greenhouses in the pond to carry out the production of hydroponic vegetables; other nutrients dissolved in water, use water push devices, and transport them to river crab breeding ponds around the purification area around the river crab pond to supply water plants such as water plants and other aquatic The growth of creatures. The Rochena shrimp is in the purification area of ​​the front and rear end of the flow sink. It is released in early May. The release specifications are 50/catties, the release density is 20 catties/mu, and the output can reach 100 catties/mu.

In addition to the above three modes, Wuzhong District also has the Rochena Shrimp and Roche Crab Pond single -set Roche shrimp and other models in Wuzhong District.

In the next step, the Wuzhong District Aquatic Products Technology Promotion Station will continue to explore the technology of river crab ponds, improve the efficient ecological breeding model of the "river crab+N" in the region, and truly achieve one more water and more water. The production capacity of existing standardized farming ponds has continuously improved fishery efficiency, and strives to promote the high -quality development of fisheries in the region.
