近几年来,我国对虾养殖发展迅速,已是当今世界上产量最高的养虾大国,年产量约占全世界总产量的1/3,已取得显著的经济效益。但随着养虾业的发展,尤其是高密度养殖的推广,加上管理不善、投饵不当、养殖生态环境不良,病害种类相应增多,而且发病面积广,危害严重,影响对虾养殖的稳产和高产,威胁着养虾业发展。因此开展虾病调查和防治技术的研究,及时提出控制虾病的措施,已是当务之急。本文报导我省1988～1991年中国对虾养成期的病害情况和预防措施研究的结果。
In recent years, the rapid development of shrimp farming in China has become the largest shrimp producing country in the world with the annual output accounting for about one-third of the total output of the world and significant economic benefits have been achieved. However, with the development of shrimp industry, especially the promotion of high-density farming, coupled with poor management, improper feeding, poor ecological environment for breeding, a corresponding increase in disease types, and the incidence of a wide area, serious harm to the stability of shrimp farming and High-yielding, threatening the development of shrimp industry. Therefore, the investigation of shrimp disease and prevention and control technology research, timely control of shrimp disease measures, is a top priority. This paper reports the results of the research on the disease situation and preventive measures in the breeding period of shrimp from 1988 to 1991 in our province.
