Abstract: Crucian carp Carassiusauratus Linnaeus with body length of about 20 cm reared in a 3 m×2 m×1.5 m tank were divided into 3 groups, control group without any surgery (n=5), sham-tag group with surgical operation and without any implants (n=5) and the test group with implantation of a ultrasonic pinger by surgery(n=5), and absolute critical swimming capacity of the crucian carp and incision healing were determined by a 1.5 kW swimming performance tank with a FLOWATCH made in Switzerland 2 h, 1 d, 3 d and 7 d after administration to study the effects of surgically implanted ultrasonic pinger with surgical suture device on swimming of crucian carp and incision healing. The results showed that the crucian carp had absolute critical swimming speed of (70.53±2.32)cm/s in the test group, (73.38±2.16)cm/s in the sham-tag group, and (82.09±2.90) cm/s in the control group, decreased by 14.06% in 2 h in the test group compared with that in the control group(P<0.05). In 1 d, however, the absolute critical swimming speed of the crucian carp in the test group was shown to returned to the normal level(80.58±3.64)cm/s, and to (79.59±1.94)cm/s in the sham-tag group, without significant difference among the three groups (P>0.05). In the 7 d experiment and observation, no death was observed in the fish with implantation of ultransonic pinger and the incision resulted from surgical suture device was kept closed, with the suture nail reservation of 95%, and without necrosis and infection. The critical time occurred negative effects was observed in fish in 2 h, and the suture device suture led to effectively shorten the suture time, which provided references for surgical suture device application in fish survey in the future.
