We examined the feeding habits of Benthosema pterotum in Kagoshima Bay. Benthosema pterotum undertook diel vertical migration and preyed in shallow waters at night. The most frequently consumed prey were copepods, and B. pterotum selectively foraged on poecilostomatoids. Poecilostomatoids were more predominant in the Kagoshima Bay zooplankton community than in neighboring sites, which suggested that the B. pterotum preference for poecilostomatoids may be an adaptation by the local population to prey availability. Benthosema pterotum probably plays an important role as a biological pump contributor and as a mediator that links secondary production and higher trophic levels.

日本南部鹿儿岛湾的瘦脸灯笼鱼 [Bentothosema pterotum (Alcock, 1890)] 的摄食习性

我们研究了鹿儿岛湾的翼螟的摄食习性。Benthosema pterotum 进行夜间垂直迁移并在浅水区捕食。最常被吃掉的猎物是桡足类，而 B. pterotum 则有选择地捕食 poecilostomatoids。Poecilostomatoids 在鹿儿岛湾浮游动物群落中比在邻近地点更占优势，这表明 B. pterotum 对 poecilostomatoids 的偏好可能是当地人口对猎物可用性的适应。Benthosema pterotum 可能作为生物泵的贡献者和作为连接次级生产和更高营养水平的介质发挥着重要作用。
