甲鱼属变温动物,水温是影响其代谢强度的重要生态因子之一。据日本资料,甲鱼在30—32℃水温下摄食最好,生长最快;低于20℃几乎不食,继而处于冬眠状态,不吃不动不长。而在我国南方一年中低于20℃水温时间有5～6个月,如何有效地利用这段时间,改变甲鱼的冬眠习性,促使甲鱼快速生长,达到高产、高效的目的,这是人们所关注的。为此,我们于1989年11月10日至1990年4月25日用当年稚甲鱼(1989年孵化脱壳
Turtle is a variable temperature animal, water temperature is one of the important ecological factors affecting its metabolic intensity. According to Japanese data, turtle food intake at 30-32 ℃ water temperature is the best, the fastest growing; less than 20 ℃ almost do not eat, and then in hibernation, do not eat for a long time. In South China in a year below 20 ℃ water temperature time of 5 to 6 months, how to effectively use this time to change the habitat of soft-shelled turtles to promote rapid growth of soft-shelled turtle, to achieve high yield and high efficiency, which is people Concerned about For this reason, we used the current year’s soft-shelled turtle (hatched and hatch in 1989) from November 10, 1989 to April 25, 1990
