The Aquaculture Technique Of Tilapia In Henan Province

This research summarized the living habits,breeding habits,growth habits and others important biological characteristics of Tilapia,also summarized the distributing and breeding state of Tilapia in home and abroad, and discussed the issues and methods in the process of culture, provided development planning for government and reference for investor and culturist of Tilapia. Through observed and analysed the water temperature of plastic greenhouse, compared to the biological characteristics of Tilapia, obtained that plastic greenhouse was fit to cultivate large-sized seed of Tilapia. Tilapia culture begin in mid-March each year was good,the times were two months, the weight of each fish could reach to 20g or more. The transparency,dissolved oxygen,PH and others important indicators of plastic greenhouse were fit to live environment of Tilapia. Through researched the relation of feeding time and weight of Tilapia, obtained that the appropriate time from cultivated large-sized fish seed to finished fish was in early in October or mid-october, and avoided hibernation was essential. Another, in this paper, according to the actual state of current production, the aquaculture technical issues were discussed about culture Tilapia. And provided several approaches and measures.Through the whole process of breeding husbandry, important notices were realized. The results showed that the aquaculture technique that used plastic greenhouse cultivate large-size fish seed to finished fish of Tilapia was successful,and the time of begin was 50 days in advance, growth cycle was shorted. And the survival rate was increased to more than 95%, genrate profit is 6136.4 yuan per 667m2.
