【摘要】 以象山港浮游桡足类优势种细巧华哲水蚤 (Sinocalanustenellus)成体为试验动物投喂以大溪地等鞭金藻(Isochrysisgalbona),对其清滤率F(ml/个·h)和滤食率G(细胞/个·h)进行了实验测定。结果表明 ,温度、海水比重、食物浓度及试验动物密度的变化对细巧华哲水蚤清滤率和滤食率均有显著影响。水温15℃、比重1.010、食物浓度150000个细胞/ml和试验动物密度0.25个/ml的条件下 ,细巧华哲水蚤滤食率达到最大。更多还原

【Abstract】 The effects of some factors on filtering rates (F, ml/ind·h) and grazing rates (G,cells/ind·h) of Sinocalanus tenellus, a dominant marine planktonic copepod in Xiangshan Harbour, were studied by feeding with the only food Isochrysis galbana. The results show that the effects of experiment temperature , water salinity, food concentration and copepod density on F and G are significant. It was found by orthogonal test that G of S. tenellus reached the maximum when the experimental factors were below: temperature 15 ℃, water specific gravity 1.010, food concentration 150 000 cells/ml and copepod density 0.25 ind/ml.更多还原
