中文摘要：

分别于2010年10—12月、2010年11月—2011年10月研究了手术植入虚假超声波发射器对草鱼的短期和长期影响.结果表明： 手术植入超声波发射器在术后30 d内对草鱼的生长具有明显的负面影响，30 d后这种负面影响逐渐消失；1尾草鱼及2尾草鱼分别在60 d及360 d研究周期内死亡，死亡率分别为4.2%及6.7%；术后30 d草鱼切口均已愈合，术后360 d，所有草鱼缝线均已脱落；2尾草鱼及1尾草鱼分别在60 d及360 d研究周期内通过未愈合的切口排出发射器，发射器排出率分别为8.7%及3.3%；保留在草鱼腹腔内的发射器都被自然包裹在纤维囊中，且与肠道、体壁及内脏存在多重粘连.手术植入超声波发射器应用于草鱼的超声波遥测技术是可行的，但草鱼在术后应至少暂养30 d以便切口愈合及生长恢复.

英文摘要：

In order to study the effects of surgically implanted dummy ultrasonic transmitters on grass carp Ctenopharyngodon idella, two experiments were conducted from October 2010 to December 2010 and November 2010 to October 2011. The results showed that surgical implantation of dummy ultrasonic transmitters had a significant negative influence on the growth of grass carp within 30 days following the surgery. However, the negative influence after 30 days faded away. One and two fish died during the 60-day and 360-day experiments, equivalent to the mortalities of 4.2% and 6.7%, respectively. All fish incisions were completely healed in 30 days after surgery, and all sutures were lost in 360 days after surgery. Two and one fish expelled the transmitters through the unclosed wound during the 60 days and 360 days, and the discharges were 8.7% and 3.3%, respectively. All the remaining transmitters were encapsulated in fibrous capsules and adhered to body wall, intestinal tract or viscera multiply. The result suggested that surgical implantation of ultrasonic transmitters could be applied to the ultrasonic telemetry research on grass carp. Nevertheless, the grass carp should be given for at least 30 days with the purpose of incision healing and growth recovery from the surgical procedure.
