A portable electro-immobilization and laparoscopy system is described that is suitable for sex determination, gonadal biopsy and immediate release of largemouth bass Micropterus salmoides. Continuous direct current at a power density of 52·2 µW cm⁻¹ for 2 min was sufficient to immobilize fish for surgery, but induced a mild, transient hypokalaemia and hyperglycaemia. Insertion of a 4·8 mm laparoscopic instrument set through the urogenital pore provided access to the gonads for examination and biopsy with mild tissue trauma.
一种便携式电麻醉和腹腔镜系统，适用于大口黑鲈 Micropterus salmoides 的性别鉴定、性腺活检和即刻释放。持续直流电功率密度为 52.2µW/cm²，持续 2 分钟，足以使鱼类在手术中保持不动，但会引起轻度、短暂的低钾血症和高血糖症。通过尿殖孔插入一套 4.8mm 的腹腔镜器械，可进入性腺进行检查和活检，组织创伤轻微。
