The effectiveness of lidocaine HCI (lidocaine HCI/sodium bicarbonate mixture) was tested as an anaesthetic for Rhynchocypris oxycephalus and R. steindachneri at three different temperatures of $10^{\circ}C.$, $15^{\circ}C.$ and $20^{\circ}C.$. Based on the exposure and recovery time, effective doses of lidocaine HCI were proven to be 300ppm ($20^{\circ}C.$), 400ppm ($15^{\circ}C.$), and 600ppm($10^{\circ}C.$) for R. oxcephaus, and 400ppm ($20^{\circ}C.$), 500ppm ($15^{\circ}C.$), and 600ppm ($10^{\circ}C.$) for R. steindachneri respectively. Anaesthetic dose and temperature-dependent relationship in exposure and recovery time were obseved for these two Rhynchocypris spops. There were size-related increases of exposure time on R. steindachneri in each dose of lidocaine HCI. However, dost-dependent increase of recovery time wea found in only the large size group of Rhynchocypris spp.

어류를 채란채정, 표지, 계측 및 수술하기 위하여 공기 중에서 취급할 때 받는 스트레스를 최소화하기 위해서나, 일정 용기로 다량의 어류를 장시간에 걸쳐 효율적으로 운반하기 위하여 마취는 매우 중요시 된다. 본 연구는 쥐노래미 Hexagrammos otakii (Jordan and Starks)의 공기중에서의 효과적인 취급과 쥐노래미를 대상으로 한 양식생물학적 연구시 간편한 취급을 위하여, 쥐노래미를 대상으로 인체에 무해하여 안전성이 높은 염산리도카인-중탄산나트륨(lidocaine HCl/NaHCO$_3$)을 사용시 그 수온별 마취 효과를 조사하였으며, 일정 마취수온에서의 염산리도카인-중탄산나트륨과 MS-222(methanesulfonate)의 마취 효과를 비교 평가하였다.

Recently, less toxic and more effective anaesthetics are essential for marine fishes. Lidocaine belongs to a group of anaesthetics which are used as local anaesthetic in human medicine. This chemical was tested fer winter flounder, Pleunnectes americanus. Anaesthetic effect of lidocaine hydrochloride-sodium bicarbonate mixture (lidocaine $HCl/NaHCO_3$) was tested for the winter flounder at five different temperature regimes: $3^{\circ}C,\;7^{\circ}C,\;11^{\circ}C,\;15^{\circ}C\;and\;19^{\circ}C$ Anaesthetic dose and temperature-dependent relationship in exposure and recovery time were observed for the winter flounder of $17.2{\pm}0.1cm$ mean total length. Based on the results, anaesthetic lidocaine $HCl/NaHCO_3$ showed rapid exposure time and rapid recovery time for winter flounder. The results indicate that lidocaine $HCl/NaHCO_3$ can be used as suitable anaesthetic for this species.

The experimental transportation of Rhynchocypris steindachneri was carried out to study the effects of lidocaine-hydrochloride on water parameters. The dissolved oxygen, ventilation rate, ammonia nitrogen, and pH of control group, sham control group, and lidocaine-hydrochloride treated groups of 2,5 ppm, 5 ppm, 10 ppm and 20 ppm at time of 30 min, 60 min, 90 min, 120 min, 240 min and 360 min after elapsed from treatment were tested. During the experiment time it was found that lidocaine-hydrochloride treated groups were most effective, followed by sham control and control, in decreasing the oxygen consumption and the excretion of ammonia by the fish. There were lidocaine-hydrochloride dose-related decrease in oxygen consumption and the excretion of ammonia. Decreasing in pH value of lidocaine-hydrochloride groups and sham control group was much more higher than that of control group. These results reveal lidocaine-hydrochloride is effective as sedative for transportation mixture in R. steindachneri.

Two cases of canine intervertebral disc disease (IVDD) were treated twice a week with injection-acupuncture (injection-AP) using 0.1 ml/acupoint. In case 1, a paralysed dog with cervical intervertebral disc disease (C3-C4), was submitted to injection-AP with dexamethasone (1 mg/ml) at session 1-2 and thiamine (25 mg/ml) at session 3-5. Injected acupoints included GV-16, GB-20, BL-10, LU-7, LI-4 and SI-6. The acupoints GV-6, GV-20 and SP-6 were added at session 2-5. Trigger point (TP) therapy with 0.2 ml of 2% lidocaine was used in session 3-5 at TP in the infraspinatus and triceps muscles. Treatment was stopped when paralysis disappeared after 5 injection-AP treatments; there were no recurrent symptoms in the follow-up period of 5 months. In case 2, an ataxic dog with lumbar IVDD (L1-L2), was submitted to injection-AP with dexamethasone at session 1 and 2 and thiamine at session 3-4. Injected acupoints included GV-6 as the main point, ST-36, GB-30, ST-40, GB-34, ST-41 and BL-40. TP therapy with 0.2 ml of 2% lidocaine was used at TP in the ileocostorum lumborum and quadriceps muscles. Treatment was stopped when ataxia disappeared after 4 treatments; there were no recurrent symptoms In the fallow-up period of 5 months. Injection-AP using dexamethasone and thiamine, combined with TP therapy using lidocaine, effectively alleviate the symptoms of canine cervical and lumbar IVDD.

The efficacy of lidocaine hydrochloride and Clove oil as anaesthetics was evaluated in the Korean rose bitterling, Rhodeus uyekii (Mori, 1935) and oily bitterling, Acheilognathus koreensis (Kim and Kim, 1990) at four different temperatures of $10^{\circ}C,\;15^{\circ}C,\;20^{\circ}C$ and $25^{\circ}C$. When complete anaesthesia was acquired less than 3 min and recovery was acquired less than 10 min, the optimal dose range of lidocain hydrochloride at $20^{\circ}C$ was 250${\~}$550 ppm in Korean rose bitterling, and 150${\~}$550 ppm in oily bitterling, respectively. In case of Clove oil, the optimal dose range at $20^{\circ}C$ was 40${\~}$200 ppm in Korean rose bitterling and 80${\~}$240 ppm in oily bitterling, respectively. Both of lidocaine hydrochloride and Clove oil resulted in a negatively dose-dependent manner for anaesthesia induction time in these two species. Recovery times were more variable in relation to anaesthetic doses, but in general higher anaesthetic doses resulted in similar or longer recovery time. As expected, the lower temperature resulted in longer anaesthesia induction and recovery time. The study demonstrated that lidocaine hydrochloride and Clove oil can be used as effective anaesthetics in these two species. The results from this study could be useful for aquaculturists industry and other related husbandry practices that require anaesthesia of Korean rose bitterling and oily bitterling.

To assess the effect of anaesthetic on stress response in cultured sweetfish (Plecoglossus altivelis) during transportation, the levels of plasma cortisol, glucose, lactic acid, $Na^+,\;K^+,\;Cl^-$, osmolality and survival were determined. The transportation was performed in square boxes where liquefied oxygen was saturated in polyethylene bags. Fish transportation was carried by car for 2 hours after anaesthesis with lidocaine-HCl/1,000 ppm $NaHCO_3$ in experiment. Mean plasma cortisol concentration before transportation was 170.7ng/ml. After transportation, the levels of plasma cortisol increased to 518.5ng/ml (Control), 461.9ng/ml (Sham control), 369.4ng/ml (20ppm anaesthetic), 304.0ng/ml (40 ppm anaesthetic), 405.7ng/ml (80 ppm anaesthetic) and 499.1ng/ml (160ppm anaesthetic) in each experimental groups, respectively (p<0.05). However levels of glucose, lactic acid, $Na^+,\;Cl^-$ and osmolality in 40ppm anaesthetic group did not show significant differences in this before and after transportation (P>0.05). These result reveal an anaesthetic lidocaine HCl/1,000ppm $NaHCO_3$ is effective as sedative for transportation mixture in this species. This research provides baseline data on cortisol, glucose, lactic acid, $Na^+,\;K^+,\;Cl^-$, osmolality and survival for anaesthetic transportation.

Anaesthetic effect of lidocaine hydrochloride-sodium bicarbonate mixture $(lidocaine\;HCL/NaHCO_3)$ and tricaine methanesulfonate (MS-222) was tested for the greenling (Hexagyammos otakii) at three different temperature regimes: $12^{\circ}C,\;8^{\circ}C\;and\;24^{\circ}C.$ Based on the exposure and recovery time, effective dose of lidocaine $HCl/NaHCO_3$ was 800 ppm $(18^{\circ}C)\;and\;300\;ppm\;(24^{\circ}C)$ for greenling of $21.0\pm1.4\;cm$ body length. Anaesthetic dose and temperature-dependent relationship in exposure and recovery time were observed. Effective dose of MS-222 at $18^{\circ}C$ was proven to be 125 ppm and 150 ppm. Combination of lidocaine $HCl/NaHCO_3$ and MS-222, considerably reduced the dosage of each anaesthetic required to give rapid, deep anaesthetic condition. In the dry exposure after anaesthetic, the control fish exhibition $22\%$ mortality after dry exposure of 20 min; whereas, the anaesthetic condition with 800 ppm lidocaine $HCl/NaHCO_3$ for 1 min exhibited delayed recoveries from the anaesthetic condition with mortalities of $20\%,\;41\%,\;78\%\;and\;100\%$ after dry exposures of 8 min, 12 min, 16 min and 20 min, respectively. The results indicate that lidocaine $HCl/NaHCO_3$ can be used as suitable anaesthetic for the greenling.
