8、面的迅速擴(kuò)大,養(yǎng)殖品種的增多,目前我國的水產(chǎn)品總量已躍居世界第一,人均水產(chǎn)品的占有量增加數(shù)倍,水產(chǎn)品的出口也明顯增長,水產(chǎn)養(yǎng)殖業(yè)已明顯成為我國21世紀(jì)的重要經(jīng)濟(jì)增長點n1。由于養(yǎng)殖的集約化水平的提高、飼養(yǎng)管理水平的低下以及養(yǎng)殖環(huán)境的不斷惡化,導(dǎo)致了細(xì)菌性疾病在水產(chǎn)養(yǎng)殖過程中廣泛存在,時有發(fā)生,具有傳染性、爆發(fā)性流行等的特點,因而常給水產(chǎn)養(yǎng)殖帶來極大危害,對病原微生物進(jìn)行及
