以象山港的优势海洋浮游桡足类细长鱼为食，以唯一食物等鞭金藻为饵料，研究了一些因素对细长鱼滤过率（F，ml/ind·h）和取食率（G，细胞/ind·h）的影响。结果表明，实验温度、水体盐度、食物浓度和桡足类密度对F和G影响显着。正交试验发现，在温度15℃、水比重1.010、食物浓度150 000个/ml、桡足类密度0.25 ind/ml的实验条件下，柔嫩细线藻G达到最大。
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.
