1993年4月中、下旬开始暴发的全国性的流行性养殖对虾病害,不但使养殖生产损失惨重,而且使为对虾生产服务的配套产业的经济也都受到极严重的影响。水产专家们的调查研究认为,这次养殖对虾病属于暴发性流行性,其发病特点是发病早、来势猛、传播快、面积大、范围广、死亡重、治疗难。病因病原是多方面的和综合性的,有病毒、细菌引起的,也有因海洋环境污染,而引起大批死亡。此外,由于亲虾和虾苗先天不足,体质差,甚至带病菌病毒;养殖上放苗密度过大,饵料质量差,过量投喂,造成水域富营养化;有的又滥用乱用药物,以及养殖生产人员技术素质差,没有严格按对虾养殖技术规范操作等等。 为从根本上防治养殖对虾病害,需要加强科学研究,特别是基础研究,对病因、病原、病理和防治办法作全面、系统、深入的研究。我认为,今年对虾还是要养,
The nationwide epidemic prawn disease outbreak that started in mid and late April 1993 not only caused heavy losses in aquaculture production but also severely affected the economy of the supporting industries serving shrimp production. According to the survey and research conducted by aquatic experts, the epidemic of shrimp farming is an epidemic characterized by early onset, fierce tendency, rapid spread, large area, wide range, heavy death and difficult treatment. The etiology is multifaceted and comprehensive. Viruses and bacteria cause pollution as well as a large number of deaths. In addition, due to the inherent shortage of broodstock and shrimp, poor health and even with germs and viruses; breeding densification density is too large, poor quality of feed, over-fed, resulting in eutrophication of the waters; and some abuse of indiscriminate use of drugs, and aquaculture production Personnel poor technical quality, not strictly according to shrimp farming technical specifications and so on. In order to fundamentally prevent and control shrimp diseases, we need to strengthen scientific research, especially basic research, and make a comprehensive, systematic and in-depth study on the etiology, pathogens, pathologies and prevention and treatment methods. I think shrimp should be kept this year,
