假设采用腹腔注射时，要防止扎针太深伤及鱼体内脏，可在注射针头上套一小截塑料管或剪短针头，暴露出的针尖长度略长于鱼体腹肌厚度。
由于鱼类种苗大多对溶解氧等水质因子要求较高，抗应激能力较差，对环境胁迫敏感，免疫接种过程中稍不注意就可能发生损伤鱼类甚至导致死亡的意外，给疫苗接种操作带来了一定的难度。
因此按常规法取养殖池、塘、网箱水域水样，检测水质的盐度、溶解氧、氨氮、亚***盐等理化因子，并结合经验性水色观察，判断水质质量，必要时做优势藻类镜检分析，以确认是否存在有害藻类优势种群。通常选择在天气晴朗、水温适宜的早晨进行鱼体免疫，在施行免疫前，首先要确认待免鱼健康：通过询问养殖业主了解待免鱼的生长、摄食、有无病史与用药史、周边其他养殖尤其是与

待免鱼同类养殖的病史。抽样镜检待免鱼3-5尾，观察体表、摄食是否正常；按常规方法镜检寄生虫。免疫前1天，待免鱼需停饲〔饵〕一天。
2、注射免疫操作
鱼类注射免疫操作，如一般动物注射一般，将药液配伍完毕，即可进行。1瓶500尾份“草鱼出血病冻干苗〞可配1瓶100ml“草鱼烂鳃赤皮败血三联苗〞或者1瓶100ml “鱼嗜水气、温和气单胞菌灭活二联苗〞。注射时， ml； ml。
注射的部位，鱼类皮下注射操作难度较大，国内一般采用肌肉注射和腹腔注射。肌肉注射一般采用背鳍基部，-，与鱼体呈30-40°的角度，向头部方向进针。，根据鱼体大小以不伤及脊椎骨为度。肌肉
