彭泽鲫养殖受水生态影响大,为了研究水生态因子、气象因子对彭泽鲫生长的影响,建立了彭泽鲫养殖观测试验点,设置了水温、pH、溶解氧等水生态因子观测项目和彭泽鲫生长体宽、体质量、病害等生长状况监测等项目,对2012年-1年的观测资料统计分析表明:1)彭泽鲫生长过程非匀速进行的,不同阶段生长速度差异大,在2012年7月-9月底,观测到快速的生长期;2)彭泽鲫生长过程伴随着质量、外形的增大,饱满度和健壮程度也不断增强;3)观测点各层水1日之内的变化曲线接近正旋曲线,振幅随着水深的增大而减小,溶解氧值的日变化主要与太阳高度有关,白天太阳高度越高,光照越强,溶解氧值越大;4)彭泽鲫生长与水温、溶解氧浓度关系大,水温过低则生长缓慢,而水温过高亦不利于生长,水中溶解氧浓度过低,会直接威胁水生生物的生命,但并非溶解氧浓度越大,彭泽鲫生长就越快,溶解氧浓度在5.0～7.0 mg/L之间,有利于彭泽鲫生长。
In order to study the effect of aquatic factors and meteorological factors on the growth of Pengze crucian carp, the experiment of crucian carp observation was established and the water ecological factors such as water temperature, pH and dissolved oxygen were set up And Pengze crucian carp growth body width, body weight, disease and other growth monitoring and other projects, from 2012 to 1 year statistical analysis of observed data show that: 1) Pengze crucian carp growth process is not uniform, the growth rate of different stages of large differences , The rapid growth period was observed from July to the end of September 2012. 2) The growth of plum carp was accompanied by the increase of the quality and the shape of the carp. The plumpness and robustness also increased continuously. 3) The variation curve within the diurnal period is close to the forward curve, and the amplitude decreases with the increase of the water depth. The diurnal variation of the dissolved oxygen value is mainly related to the solar altitude. The higher the solar altitude in daytime, the stronger the light intensity and the greater the dissolved oxygen value. 4) Pengze crucian carp growth and water temperature, dissolved oxygen concentration, water temperature is too low, slow growth, and the water temperature is not conducive to growth, the dissolved oxygen concentration is too low, will directly threaten the life of aquatic organisms, but not dissolved oxygen The greater the concentration, Pengze crucian carp growth Fast, the dissolved oxygen concentration between 5.0 ~ 7.0 mg / L, is conducive to the growth of Carassius auratus.
