饵料浓度对中华哲水蚤摄食的影响
Effect of concentration of food particles on the feeding behavior of the marine planktonic copepod Calanus sinicus

摘要: 用饵料浓度差减法和排粪率法研究中华哲水蚤(Calanus sinicus)在饵料(青岛大扁藻、新月菱形藻)浓度从1500到350000个/cm3时摄食率的变化。实验证明中华哲水蚤具有很强的摄食潜力,摄食率在实验饵料浓度范围内一直在增加,在较低的饵料浓度(如青岛大扁藻4000个/cm3)下停止摄食。Abstract: Using Platyrnonas halgolankeca and Nitzschia closterium (Ehrenb) as food,the batch culture feeding experiments and fecal pellets production rate experiments are carried out to study the effect of food particle concentration on the feeding behavior of Calanus sinicus.The ingestion rate (expressed as fecal production rate) of every C.sinicus increased from 0 to 100 pellets/d with the increase of food concentration,even when the food concentration was very high (200 000 and 380 000 cells/cm3 for P.halgolankeca and N.closterium repectively).
