Preliminary study on evaluation benchmark of ecological suitability of water temperature in grass carp(Ctenopharyngodon idella)culture pond
摘要
Abstract
Grass carp(Ctenopharyngodon idella)is the most productive species of freshwater fish farmed in ponds in China.Water temperature in the pond is one of the key factors to determine whether it can survive and grow healthily.Based on the existing literature,the ecological suitability of water temperature to the growth and survival of grass carp was divided into five grade periods.The impact of water temperature on the physiology and ecology of grass carp were systematically reviewed,and the temperature(t)benchmarks(range)of five ecological suitability grade periods were determined.The benchmarks(t)were as follows:death period t≤2.0℃ or t≥38.0℃,dan-gerous period t∈(2.0,4.0)℃ or t∈[35.0,38.0)℃,influence period t∈[4.0～18.0)℃ or t∈(33.0～35.0)℃,normal period t∈[18.0～26.0)℃or t∈(30.0～33.0]℃ and optimal period t∈[26.0～30.0]℃.The results are helpful to guide farmers to carry out the safe management of pond water temperature and the adjust-ment of ecological suitability,and promote the healthy development of grass carp aquaculture industry.关键词
