结合2014-2015年江西省彭泽县鲢鱼养殖生态、气象观测资料,对鲢鱼不同生长断面的体质量、水温之间的相关关系进行分析,同时建立起鲢鱼平均体质量预测模型。研究结果表明:1)彭泽鲢鱼生长速度较快时的水温在25~30℃,其中最适宜水温在23~28℃;2)溶解氧浓度越大,不一定有利于彭泽鲢鱼的生长,当溶解氧浓度在5.0~7.0 mg/L时,将有利于彭泽鲢鱼的生长;3)结合彭泽鲢鱼生长过程中的实际情况,分析各种气象灾害对鲢鱼生长产生的危害,以期提升彭泽县鲢鱼养殖的产量,提高渔民收入。
Based on the ecological and meteorological data of silver carp breeding in Pengze County, Jiangxi Province during 2014-2015, the correlations between body weight and water temperature of silver carp growing section were analyzed. At the same time, an average body mass prediction model of silver carp was established. The results showed that: 1) when the growth speed of Pengze silver carp was fast, the water temperature was between 25 ℃ and 30 ℃, and the most suitable water temperature was between 23 ℃ and 28 ℃. 2) The higher dissolved oxygen concentration would not be beneficial to Pengze silver carp When the dissolved oxygen concentration is 5.0-7.0 mg / L, it will be beneficial to the growth of Pengze silver carp; 3) Based on the actual situation during the growth of Pengze silver carp, the effects of various meteorological disasters on the growth of silver carp Hazard, with a view to raising Pengze County silver carp breeding output, improve fishermen's income.
