1993年6月上旬至8月中旬,全省养殖对虾普遍发病,发病面积达90％以上,直接经济损失达4亿多元,其中有4.2万亩虾塘绝产,使对虾养殖陷入了新的困境。对于今后怎样养虾的问题,我们认为虾病暴发是宿主、病原和环境之间相互作用的结果,只要从阻断病原、改善环境、优化养殖技术和药物防治等方面认真考虑,采取有效措施还是能养好对虾的。
From early June to mid-August 1993, penaeid shrimp were commonly reported in the province with an incidence of over 90% and a direct economic loss of more than 400 million yuan. Among them, 42,000 mu of shrimp ponds were in abeyance, bringing shrimp farming into a new Dilemma. We think shrimp disease outbreaks are the result of interaction between host, pathogen and environment as far as shrimp cultivation is concerned in the future. So long as we consider seriously from the aspects of blocking pathogen, improving environment, optimizing breeding techniques and drug control, effective measures are taken Can support the shrimp.
