| 摘 要： | 鱼塘细菌数量很大且经常波动。总菌数以夏季最多,依次为秋季、春季及冬季;异养菌在水层及底泥中则分别以夏季和秋季较多。异养菌数量与化学需氧量(COD)呈明显正相关。总菌数与 COD也呈正相关。水温与总菌数呈正相关,而水温与异养菌则无相关性。浮游植物与总菌数、异养菌数均无相关性。浮游动物与细菌数量却呈现正相关。细菌繁殖适宜的pH 值为6.4—9.4。促使细菌数量减少的常用水产药物,按其效力大小依次为漂白粉、CuSO_4·FeSO_4 合剂、敌百虫。

| Abstract: | The amount of bacteria in fish pond was plenty and changeable.The sequence of the total amount of bacteria was summer,autumn,spring and win-tar. In water, the organo raphs were more ixi summer, while in bottom-mud theywere more in autumn. The amount of erganotrophs and the total amount of bacteria,were correlated positively to the chemical oxygen demand (CCD). The fatal amountof bacteria showed a positive correlation to water temperature, but the organotro-phs were not. The total amonut of bacteria and organotrophs were not correlated tothe plankton biomass, but the total amount of bacteria were correlated to the zoo-planlton biomass. The suitahle pH range for growth is 6.4-9.4. The power of thecommon fisheries medicines reducing the amount of bacteria wars in order of bleeding powder>CuSo,FeSo,mixture>dipteregx |
