Zhongbao Town, Xinghua City, Jiangsu Province is located in the northwest of the city, with abundant water resources and advanced fish production technology. In 2012, the town began to develop large-scale freshwater fish for puffing and breeding, and achieved good economic benefits.
Compared with the traditional sinking hard pellet feed, the bulking material has the following advantages: First, it adopts high temperature and high pressure process, which can effectively decompose rapeseed erucic acid, gossypol and protein in the three major raw materials (vegetable meal, soybean meal, cotton aphid). Inhibition of harmful substances such as enzymes, high degree of ripening, better protection of fish liver and gallbladder; second, high crushing fineness, better digestion and absorption of fish, faster growth; third, less pollution to water, reduce feeding of mixed drugs Waste, improve the safety of aquaculture products; Fourth, the formula is more scientific, the feed coefficient is low, which can help achieve high returns and low risks.
Through the analysis of the effect of using the expanded material in Zhongbao Town in 2012, the Tangkou with the use of bulking material has a lower feed coefficient, less disease and higher benefit than the pond mouth with pure hard granular material. The household has a breeding area of ​​18 mu, the main grass carp and carp, with squid and white squid, the net weight gain of eating fish is 20,988 kg, the use of extruded material is 15 tons, the hard granule is 17.5 tons, the feed coefficient is only 1.56, and the mu is a net profit. 3,257 yuan.
In 2013, the main product of the fishery technology in Zhongbao Town is the large-scale freshwater fish. Under the guidance of the expert group, the town will further demonstrate and promote the feeding technology of the expanded material, and strive to achieve the goal of stable production and high efficiency.
