初冬或早春,当水温在5～10℃时,是亲鱼运输的适宜季节。现将采购亲鱼的常用运输法介绍如下: 一.帆布箱运输法 可依据帆布箱容积,决定运输的数量。一般密度为每吨水 100 kg鱼,3～5 t的载货车箱内设置2～3只帆布箱,共可载鱼 300～500 kg。1辆车箱内不要只放置1只大帆布箱,可以多设置几只,既可减少亲鱼的活动范围,减少机械损伤,又可充分利用车箱空间,达到多运、节约运费的目的。采用此种运输法,以在3～5小时内短距离运输效果较佳,不宜作长途运输。 为避免亲鱼在运输中激烈运动和碰伤,可将每条亲鱼放入1条事先做好的纱布袋中,并将尾部袋端扎好,然后再放入帆布箱内。纱布袋宽度和长度,要超过亲鱼的宽、长度,使亲鱼装入袋后能在帆布箱中活动自如。此种方法装运的密度和方法与不套纱布袋基本相同,但运输时间可达10小时以上,且效果较理想。
Early winter or early spring, when the water temperature at 5 ~ 10 ℃, is the appropriate season for broodstock transport. Now the purchase of broodstock commonly used transport method is described below: I. Canvas transport method Can be based on the volume of canvas, decided to transport the number. General density of 100 kg fish per ton of water, 3 ~ 5 t truck box set 2 to 3 canvas boxes, a total of 300 ~ 500 kg of fish can be carried. Do not just place a large canvas box in a car, you can set a few more, can reduce the scope of activities of broodstock, reduce mechanical damage, but also make full use of the trunk space, to achieve multi-Yun, the purpose of saving shipping costs. The use of such transport law to short-term transport within 3 to 5 hours better, not for long-distance transport. To avoid intense movement and bruising of broodstock in transit, each brood can be placed in a pre-made gauze bag and tied to the end of the tail bag before being placed in a canvas case. Gauze bag width and length, to exceed the width and length of the broodstock, so that after the parent fish into the bag can move freely in the canvas. This method of shipping density and methods are not the same sets of gauze bag basically the same, but the transport time up to 10 hours or more, and the effect is better.
