摘要
大口黑鲈(Micropterus salmoides)已成为中国淡水池塘养殖的重要物种。池塘水温(t)是决定其是否能生存和健康生长的关键因素之一。本文系统梳理了国内外涉及水温对大口黑鲈生理生态影响的研究结果,根据水温将大口黑鲈生长和生存的生态适宜度划分为5个等级期,并以此为基础确定了5个生态适宜度等级期的温度基准(范围)。分别为:死亡期t≤3.5℃或t≥35.0℃、危险期3.5℃<t<6.0℃或33.0℃≤t<35.0℃、影响期6.0℃≤t≤20.0℃或30.0℃<t<33.0℃、正常期20.0℃<t<25.0℃或28.0℃≤t≤30.0℃和最适期25.0℃≤t<28.0℃。
Largemouth bass(Micropterus salmoides)has become an important species in freshwater aquaculture pond in China.Pond water temperature(t)is one of the key factors for its survival and healthy growth.The ecological suitability of water temperature for growth and survival of largemouth bass was divided into five level periods.The research results about the physiological and ecological effects of water temperature on the largemouth bass were systematically reviewed.Based on this,the temperature benchmarks(range)of five ecological suitability level periods were determined.The benchmarks are as follows:death period t≤3.5℃or t≥35.0℃,dangerous period 3.5℃<t<6.0℃or 33.0℃≤t<35.0℃,influence period 6.0℃≤t≤20.0℃or 30.0℃<t<33.0℃,normal period 20.0℃<t<25.0℃or 28.0℃≤t≤30.0℃and optimal period 25.0℃≤t<28.0℃.
