天津市地处渤海湾湾顶,有150多公里的海岸线。在“七·五”期间,天津的养虾业有了较大的发展。目前养殖面积已达7万多亩,产量也在逐年提高。但随着养殖面积的不断增加,养殖年限的加长,虾病的流行日趋严重,并造成很大的经济损失,严重地威胁着我市养虾业的发展。对于虾病的防治方法,国内外许多专家正在进行研究,但还没有得到很好的解决。为了摸清天津地区养殖对虾(中国对虾)疾病类型及流行情况,我们于1988-1990对中国对虾的幼体、成虾及越冬亲虾的病害、病原生物学及流行病学等进行了调查研究。通
Located in the top of Bohai Bay, Tianjin has over 150 kilometers of coastline. During the “Seventh Five-Year Plan” period, the shrimp industry in Tianjin has made great progress. The current breeding area has reached 70,000 mu, the output is also increasing year by year. However, with the continuous increase of breeding area and the prolongation of breeding years, the epidemic of shrimp disease is becoming more and more serious, causing great economic loss and seriously threatening the development of shrimp industry in our city. For the prevention and treatment of shrimp disease, many experts at home and abroad are studying, but it has not been well resolved. In order to find out the types and prevalence of P. shrimp (shrimp) in Tianjin, we conducted a survey in 1988-1990 on the diseases, pathogens and epidemiology of juveniles, adult shrimp and overwintering shrimp in China. through
