星洲红鱼对温度适应性的研究
The study on the temperature tolerance of Red Tilapia
摘要
Abstract
In this paper,the temperature tolerance of Red Tilapia was studied under the condition that 20℃ was the initial temperature with gradually change of water temperature(increasing or decreasing 1℃ everyday,at the rate of 0.5℃ per 12 hours),suddenly increase(2℃,4℃,6℃,8℃,10℃,12℃,14℃,16℃,18℃,20℃),and suddenly decrease(2℃,4℃,6℃,8℃,10℃,12℃,14℃),respectively.In gradually increasing and decreasing water temperature experiments,the results showed that the adaptation temperature of Red Tilapia was in the range from 8℃ to 40℃,and the critical survival temperature was from 14℃ to 36℃.The death temperature,the lethal temperature,the critical lethal temperature and the fatal high temperature were(7.82 ± 0.21)℃,(5.67 ± 0.16)℃,(38.36 ± 0.21)℃,(39.83 ± 0.15)℃,respectively.With suddenly change of water temperature,the results showed that Red Tilapia was able to adapt the suddenly increase change of 16℃(20℃→36℃),and only adapt the suddenly decrease change of 8℃(20℃→12℃).关键词
