近几年来,随着对虾养殖业的迅速发展,养殖区水质环境越来越坏,对虾致病因子逐年增多,去年虾病感染面积达80％以上。经济损失严重,给对虾养殖业的稳步发展带来很大障碍,引起各级领导和有关科研及生产部门的关注,并从各个角度支持开展虾病防治技术的研究,在药物防治方面取得了一定成效。但由于养殖面积大,虾池水量多,耗药数量大,养殖者经济负担重,因此,未能收到理想的效果。近年来,一些厂家着手开发药饵产品,由于药物饵料用药经济,处理方便,对病虾作用直接,疗效较好,且不影响养殖环境,也不易发生机械损伤和二次污染,已经逐渐 In recent years, with the rapid development of shrimp aquaculture, aquaculture water quality and environment is getting worse and worse, shrimp pathogenic factors increased year by year, shrimp last year infected area of ​​more than 80%. The severe economic losses have brought great obstacles to the steady development of shrimp farming, aroused the concern of leaders at all levels and relevant scientific research and production departments, supported the research on prevention and treatment of shrimp diseases from all angles, and achieved certain results in drug control Effective. However, due to the large area of ​​breeding and the large amount of water in shrimp ponds and the large amount of drug consumption, farmers have a heavy economic burden and therefore fail to receive the desired results. In recent years, some manufacturers set out to develop drug bait products. Because of the economical and convenient treatment of drug bait, it has a direct and effective curative effect on diseased shrimp and does not affect the breeding environment, and is not prone to mechanical damage and secondary pollution.
