当前,农业和农村经济发生了阶段性变化,主要农产品(包括水产品)出现了阶段性、低水平的过剩。在其影响下,我市目前养鱼生产增长速度缓慢,养鱼经济效益明显下降。为使渔业生产摆脱目前不利的困境,发展低耗高效生态型渔业实属明智之举。它不但可以提高经济效益,而且还能提高社会效益、生态效益和综合效益。 At present, the agricultural and rural economy has undergone a phased change. The major agricultural products (including aquatic products) have been staged with a low level of surplus. Under its influence, the current growth rate of fish production in our city is slow, and the economic benefits of fish culture are obviously reduced. In order to get rid of fishing production from the current unfavorable predicament, it is wise to develop a low-cost and efficient eco-friendly fishery. It can not only improve economic efficiency, but also improve social, ecological and comprehensive benefits.
