| 摘 要： | 为了研究投喂两种不同饲料(冰鲜下杂鱼与配合饲料)对大口黑鲈养殖水质指标的影响,在室内水泥池进行了28d的饲养试验.对水体中的COD、PO4--P、TP、TN、NH3-N、NO3--N、NO2-N等指标进行了测定.结果表明,投喂两种饲料各指标均有不同程度的增加,但养殖一个月后冰鲜组比饲料组要高许多:杂鱼组COD、PO4--P、TP、TN、NH3-N、NO3--N、NO2--N分别为25.3mg/L、2.4mg/L、2.28mg/L、3.44mg/L、2.91mg/L、0.52mg/L、0.075mg/L,而配合饲料组分别为10.2mg/L、0.58mg/L、0.855mg/L、2.17mg/L、0.29mg/L、0.048mg/L、0.03mg/L.特别是PO4--P、TP,冰鲜组分别为饲料组的4.2倍和2.7倍.这说明投喂人工饲料可以减轻有机污染程度,特别是在控制PO4--P、TP的增加方面效果显著.试验结果对于控制水体的富营养化具有重要的指导意义.

| Abstract: | A 28-day trial was conducted to study the effects of feeding iced trash fish and formulated feed food on the water quality in largemouth bass (Micropterus salmoides) aquarium. The COD, PO4--P, TP, TN, NH3-N, NO3--N and NO2--N were determined respectively. The results showed that all the index were increasing with feeding the two kinds of feedfood, but feeding the trash fish was much higher than feeding the formulated feedfood. The COD, PO4--P, TP, TN, NH3-N, NO3--N and NO2--N of feeding trash fish were 25.3... |
