近年来,由于水产养殖环境和自然环境污染,造成养殖动物生活环境(包括生物、物理及化学等因素)不断恶化,导致病原微生物种类增多和传播速度加快,养殖生物病害发生日趋严重,给水产养殖业带来巨大损失。在水产动物病害防治方面,目前广泛使用的鱼用消毒剂、抗菌药、杀虫药物存在不同程度的消毒不稳定、产生耐药性、残留量大或污染环境等问题。随着人们健康、环保意识的加强,微生态制剂因被认为属于无毒副
In recent years, due to the pollution of aquaculture environment and natural environment, the living environment (including biological, physical and chemical factors) of breeding animals has been deteriorating. As a result, the number of pathogenic microorganisms and the speed of transmission have been increased, and the occurrence of aquatic biological diseases has become increasingly serious. Industry has brought huge losses. In aquatic animal disease prevention and control, currently widely used fish disinfectants, antibacterials, insecticides exist varying degrees of disinfection instability, resulting in resistance, residual large or pollute the environment and other issues. With the improvement of people’s health and environmental awareness, probiotics are regarded as non-toxic
