鱼种长途运输一般在水温5—10℃低温时节进行。这时鱼种空腹紧鳞,代谢减弱,少活动,耗氧少,是成功运输的先决条件,但运输中操作人员必须严格把握如下技术要点: 1、充分准备运输前,操作人员要熟悉行车路线,确定可靠的加水地点,安全检测车辆,装鱼器皿试水等,尽可能提高运输途中安全系数。 2、练箱拉网后鱼种练箱2小时以上,使鱼种充分排泄,适应在高密皮下运输,淘汰劣质鱼种。尽量减轻运输水中不必要的负担。 3、带水操作切忌干挑上车,特别是挑距较远的定要带水操作,避免鱼种受伤或缺氧死亡。 4、合理调节体内外渗透压在运输水中加放一定量的食盐,使浓度为1.5—2‰,防治鱼
Long-distance transport of fish generally in the water temperature 5-10 ℃ low temperature season. At this time, fasting tight scales fish species, weakened metabolism, less activity, less oxygen consumption is a prerequisite for successful transport, but the transport operator must strictly grasp the following technical points: 1, fully prepared for transport, the operator must be familiar with driving directions , Determine the location of reliable water, safety testing vehicles, fish containers and other test water, as far as possible to improve the transport safety factor. 2, practicing chest pull net fish species box more than 2 hours, the full excretion of species to adapt to the transport under high density, eliminate inferior species. Minimize the unnecessary burden on transport water. 3, with water operations should not pick and pick the car, especially to pick away from the set to bring water operations, to avoid fish injuries or hypoxia death. 4, a reasonable regulation of in vivo and in vitro osmotic pressure Add a certain amount of salt in the transport water, so that the concentration of 1.5-2 ‰, prevention and treatment of fish
