实践证明,澄湖无公害养殖管理技术的多年探索结果,使养殖对象结构逐年优化、品种档次不断提高,特种水产品经济比例高达近30%,放养鱼种回捕率稳定在80%以上,职工年收入相应增加,产量和利润分别比探索前的1998年增加1.6倍和3.3倍。生产要素和资源优化组合,强化湖区生产秩序与港口防逃设施管理,定能获得显著的养殖效果、生态效能和经济效益,实现湖泊渔业经济的稳定、健康和可持续发展。 Practice has proved that many years of exploration and management of pollution-free aquaculture in Chenghu have resulted in the optimization of the structure of breeding target year by year and the continuous improvement of breed grades. The economic proportion of special aquatic products is as high as nearly 30%, and the recovery rate of stocking fish species is stable at over 80% The corresponding increase in annual income, output and profits were 1.6 times and 3.3 times higher than that of the pre-exploration year of 1998 respectively. The combination of factors of production and resources, and the strengthening of the production order in the lake area and the management of harbor anti-flee facilities will surely achieve significant breeding effects, ecological benefits and economic benefits, and achieve a stable, healthy and sustainable development of the fishery economy.
