随着集约化养殖的发展,草鱼养殖病害发生呈上升趋势,为防治病害超量使用抗生素、化学药物等,导致耐药菌株增加,药物残留、环境污染加重。因此使用天然环保无残留的免疫增强剂防治鱼病逐渐受到重视。本研究旨在验证不同含量天然免疫调节剂对草鱼抗病能力、生长性能和养殖效益的影响,为草鱼健康养殖提供支持。
With the intensive development of aquaculture, diseases of grass carp breeding are on the rise. Excessive use of antibiotics, chemical drugs and the like for the prevention and treatment of diseases has led to the increase of drug-resistant strains, drug residues and environmental pollution. Therefore, the use of natural environment-free residual immune enhancer control of fish disease gradually attention. This study aimed to verify the different content of natural immune modulators on grass carp disease resistance, growth performance and breeding efficiency, to provide support for the healthy grass carp culture.
