为寻求长途运输活鱼的理想方法,日本环境科学综合研究所采用CO_2将鱼麻醉后运输和不同低水温运输活鲤鱼的比较试验.结果发现:用CO_2将鱼麻醉后运输有两点不足,一是诱发鱼类麻醉的时间太长;二是使用浓度范围太窄.采用低温运输可克服以上不足.在23℃水温中生长的鲤鱼移入4℃的水中,可安全保持麻醉状态5小时,但鱼接受
In order to find an ideal method for long-distance transport of live fish, the Japan Institute of Environmental Science integrated CO2-fish into anesthetized fish and comparatively tested the transport of live carp with different low temperatures. The results showed that there were two deficiencies Is to induce fish anesthesia time is too long; the second is the use of concentration range is too narrow.Using low-temperature transport to overcome the above shortcomings in the 23 ℃ water temperature in the growth of carp into 4 ℃ water, can safely maintain the state of anesthesia for 5 hours, but the fish accept
