The situation of seedling production in Yangjiaopan Aquatic Seedling Plant in Haiyang City, Shandong Province is gratifying.

The production situation of Yangjiaopan Aquatic Seedling Plant this year is gratifying, with nearly 10,000 cubic meters of breeding water, breeding 400 million seedlings such as Japanese shrimp, Penaeus chinensis and swimming crab. By the end of May, the income from breeding of Penaeus chinensis alone had reached 400000 yuan.

A few days ago, during an interview at the Yangjiaopan Aquatic Seedling Plant in Haiyang City, the reporter saw that a large number of Penaeus chinensis seedlings are being bred in more than a dozen shrimp ponds, and the staff are strictly implementing the technical regulations according to the relevant shrimp seedling breeding techniques to carry out meticulous culture and care for all kinds of shrimp seedlings. It is understood that Penaeus chinensis seedlings grow rapidly, have strong disease resistance, have a large head and high yield after maturity, and are welcomed by the majority of aquaculture farmers.

Wang Zhongshan, director of Yangjiaopan Aquatic Seedling Factory: this year, this Chinese shrimp has bred a total of 18 ponds, with an estimated output of more than 70 million, and the market price is 60 yuan and 10,000 yuan.

It is understood that since the beginning of spring, the factory has successively introduced high-quality parents such as Penaeus chinensis, Japanese shrimp and swimming crab, and produced the first and second generation virus-free seedlings through techniques such as gonadal maturation, indoor natural mating, spawning and hatching. Among them, the average specification of Penaeus chinensis has been above 1.5cm/ tail, and the large one has reached 2cm/ tail, which is mainly sold to Weihai, Qingdao, Yantai and other places.
