Villager He Yanqing was visiting the breeding base, and Li Haihan, the head of the base, explained patiently. In the net just put away, the crayfish waving blue pincers is huge and active. The scientific name of the shrimp is Australian freshwater lobster. It was introduced by the Yongxin Branch of Panjin Guanghe Crab Industry Co., Ltd. through the Ministry of Science and Technology, and began to be cultivated in July this year.

"I came here today to see this Australian freshwater lobster. I feel that it is very suitable for our farming. It is very big, has high economic benefits and has great prospects for development." He Yanqing thought that he would also raise a few acres of lobsters in the coming year.

The Australian freshwater lobster is a large freshwater crayfish native to Australia. It is called freshwater lobster because of its large size, similar appearance to sea lobsters, and only living in fresh water. The individual generally weighs 100 to 200 grams, and the meat is firm and delicious. It is one of the rare and economical shrimp species.

"The survival rate of this shrimp is still good. At present, it can reach 80%-90%. The average price is 15 yuan per piece. Compared with ordinary crayfish, its profit will be higher." Li Haihan, the person in charge of the base, told Reporter, the newly introduced Australian freshwater lobster adopts the rice-shrimp co-cultivation model. Since it is a trial cultivation stage, a total of 5 mu of land has been cultivated. After 3 months of careful cultivation, initial results have been achieved.

Behind the successful trial cultivation of Australian freshwater lobster, it is inseparable from the support of technology. Through study and experimentation, Li Haihan found a set of methods suitable for breeding Australian freshwater lobsters in Yongxin: First, to seize the high temperature season in summer, Australian freshwater lobsters can grow rapidly in a high temperature environment. The second point is the most important water quality adjustment.

In half a month, this batch of Australian freshwater lobsters will be on the market. At present, the base has received a large number of orders, and they will basically be sold out. Seeing that the shrimps he raised are so popular, Li Haihan has further plans for the future: "Next year, we will raise 50 mu, and the yield per mu should reach about 200 catties, and then guide those interested villagers to raise them together and bring everyone together to increase their income. get rich."
