Abstract:
Since 1978 the market economy in China has been introduced. The only guideline of fishery development was published in 1985, and it said that the future of fishery was mainly based on aquaculture. Accordance of economic development, demand of fishery products has increased and especially demand of crab was very high. Lake Thai is the third largest lake in China, and since 1991 crab aquaculture using net fence has started. As the profit of this was very high, so many crab aquacultures were enlarged, and it has polluted the water of Lake Tai. After the abnormal propagation of blanket weed in 2007, the pollution due to crab aquaculture became a big problem. The area of crab aquaculture 13,600ha for 4,018 fishermen has decreased to 3,000ha for 3,000 full-time fishermen in the East Lake Tai only. Some part-time fishermen moved to crab aquaculture in artificial ponds around Lake Tai. This study compares the return of both types of crab aquaculture and discusses the future development considering the food safety of crab aquaculture products. Read more
