| 摘 要： | 对东海北部近海棘头梅童鱼(Collichthys lucidus)的食性从饵料组成、摄食强度、食性类型和营养级等方面进行了探讨。结果表明:棘头梅童鱼的饵料生物种类数多,组成复杂,选择范围较广,水域差异较大。其空胃率为7.59%,最高饱满指数为188.55‰,平均为24.62‰,单因素方差分析表明摄食强度的季节差异和体长组差异都极显著。棘头梅童鱼食谱较宽,主要摄食糠虾类、磷虾类和桡足类等浮游动物,兼食鱼类和长尾类等游泳动物,属浮游生物食性鱼类。通过计算其生境宽度为2.250,营养级为3.282级,属次级消费层的低级肉食性鱼类。

| Abstract: | By analyzing food composition,feeding intensity,feeding ecological type and trophic level of Collichthys lucidus in northern East China Sea,the feeding habits of Collichthys lucidus was studied.Results showed that the species number of food organisms of Collichthys lucidus was large;the composition was complex;the selection scope was wide,and there were significant differences among various water areas.The empty stomach percent of Collichthys lucidus was 7.59%,the highest stomach fullness index and the aver... |
