本文材料系1965年，1977年，1988年至1989年台湾海峡灯光围网、拖山网的渔获物。采用个体百分比（N），重量百分比（W），出现频率（F），出现频率百分比，胃饱满系数，类群更替率等指标进行分析，并根据3个指标，计算了相对重要性指标。蓝圆鲹食性广泛，主要食料有桡足矣、小型鱼类、糠虾类、长尾类和短尾类等。幼鱼食料以桡足类最为重要，成鱼食料则以鱼类为重要。蓝圆鲹摄食强度有明显的季节变化。周年摄食强度呈双峰型，高峰期正好比两个产卵期迟1个月，说明蓝图鲹生殖后强烈摄食。幼鱼摄食强度昼夜变化明显，以黄昏和黎明摄食较强烈。蓝图鲹主要饵料生物的高生物量区，可作为寻找中心渔场的良好生物学指标之一，这在生产实践中有重要意义。
This material is 1965, 1977, 1988 to 1989 Taiwan Strait lights seine, dragons net catches. The indexes of individual importance (N), weight percentage (W), frequency of appearance (F), percentage of appearance frequency, gastric fullness coefficient and population turnover rate were analyzed. Relative importance index was calculated based on three indexes. Blue Circle 鲹 food is broad, the main food with copepods, small fish, shrimp, long-tailed and short-tailed and so on. Juvenile foodstuffs are most important for copepods, and fish for fish meal are important. There is a clear seasonal change in the feeding intensity of the blue circle. Annual feeding intensity was bimodal, peak just two months later than the spawning period of 1 month, indicating that the blueprint 强 reproductive reproduction after intensive feeding. Diurnal changes in feeding intensity of juvenile fish were obvious, with strong dusk and dawn feeding. The blueprint 高 The high biomass area of the main feed organisms can be used as one of the good biological indicators for finding a central fishery, which is of great importance in production practice.
