1979年我国虾池面积只有10万亩,总产量只有1200吨,但到1988年,虾池面积猛增到244.4万亩,产量猛增到19.9万吨。十年间面积增长了25倍,产量增长了166倍。其中尤以1984～1987年的增长最为迅速,虾池面积和虾产量年平均以59％和102％的速度增长。这种超速增长,引发了一系列的机制失调,致使养虾业面临着严重滑坡的挑战。现就内部机制失调提出一些个人见解。 1.系统结构失衡从亲虾越冬、孵化育苗到养成管理(诸如饲
In 1979, the area of shrimp ponds in our country was only 100,000 mu and the total output was only 1,200 tons. By 1988, the shrimp pond area soared to 2,444,000 mu and the output soared to 199,000 tons. The area grew by 25 times during the decade and the output increased by 166 times. Especially in 1984 to 1987 the most rapid growth, shrimp pond area and shrimp production average annual growth rate of 59% and 102%. This speeding up has triggered a series of institutional imbalances that have caused the shrimp industry to face the severe landslide challenge. Now on the internal mechanism imbalance put forward some personal opinions. 1. Structural imbalances from winter broodstock, hatching nursery to develop management (such as feeding
