目前各地大鲵人工繁殖取得突破性进展,人工养殖也逐步发展起来。大鲵捕捉后在暂养时,即将胃中的食物几乎全部吐出;尔后较长时间绝食或少食。它有凶猛好斗的特性;夜晚进行残酷相抱咬打,尤其大个体经常把小个体咬伤、咬残或咬死,因此收购后密集暂养时,必须将大、中、小个体进行分养。以减少相互残杀带来的伤亡损失。大鲵有尖利锯齿状的上下颌齿,食物入口后咬住不放,咬住人的手指便急速扭转,以致手指被咬断。 人工养殖大鲵和甲鱼有些类似,主要有水温、水质、饲料和人工管理几个方面: 一、水温:水温的控制是人工养殖成败的关键,大鲵适宜的生长温度在18℃—24℃之 At present, the artificial breeding of giant salamander has made breakthrough progress and the artificial breeding has also been gradually developed. Catfish caught in the holding time, the stomach is about to spit out almost all food; then a longer time hunger strike or eat less. It has the characteristics of ferocity and aggressiveness; brutal bite at night, especially large individuals often bitten small individuals, bitten or killed, so after the acquisition of intensive maintenance, must be small, medium and small individual points support. In order to reduce the loss of casualties caused by mutual killings. The big jagged jagged jaw teeth, bite the food after the entrance, bite the fingers of people will be rapidly reversed, resulting in finger was snapped off. Artificial cultivation of big clams and turtles are somewhat similar, mainly water temperature, water quality, feed and manual management of several aspects: First, the water temperature: the control of water temperature is the key to the success or failure of artificial breeding, suitable for the growth of large clams at 18 ℃ -24 ℃
