日本研制成一种适合蓄养和搬运鱼的保温、保冷型活鱼槽。槽的内外壳是用强力塑料制成.中间装有具隔热构造的尿烷泡沫.能使夏天水温的急剧上升和冬天水温的下降.保持在最小的限度.这样即可防止由于水池内水温的急剧变化而引起鱼体衰 Japan developed into a suitable storage and handling of fish insulation, cold-type live fish tank. The inner shell of the tank is made of strong plastic with a urethane foam with heat insulation structure in the middle, which can make the temperature of the summer rise sharply and the temperature of the winter water drop down, keep the minimum limit, so as to prevent the water temperature in the tank The sharp changes in fish cause body failure
