莫斯科大学的水生物专家发明了通过水温的变化,加速鱼苗生长的办法。他们在放养鲤鱼鱼苗的鱼池里进行了试验。具体做法是:用调节器把水温控制在1—10℃之间,通过人工的方法使水温慢慢升高,然后再逐渐下降,鱼苗的生长速度高于普通鱼池的鱼苗。他们发现,如果水温每小时变化在1—1.5℃ Aquatic experts at the University of Moscow have invented ways to accelerate the growth of fry through changes in water temperature. They experimented in fish ponds that stocked carp fry. The specific approach is: with the regulator to control the water temperature between 1-10 ℃, the water temperature slowly increased by artificial methods, and then gradually decreased, the growth rate of fry than ordinary fish pond fry. They found that if the water temperature changes from 1-1.5 ° C per hour
