摘要

根据鱼的大小和摄食历史，三棘毛蚶(Peprilus triacanthus)对leidyi记忆藻的摄取率在4 ml/gm干wt/hr到184 ml/gm干wt/hr之间。这样的消耗速度提供了足够的食物来支持鱼的新陈代谢，这可能解释了在纳拉甘西特湾观察到的夏末秋初记忆藻种群水平下降的原因。

Predation on the ctenophore,Mnemiopsis leidyi, by butterfish,Peprilus triacanthus, in Narragansett Bay, Rhode Island

Consumption rates ofMnemiopsis leidyi by butterfish,Peprilus triacanthus, ranged between 4 ml/gm dry wt/hr to 184 ml/gm dry wt/hr, depending on fish size and feeding history. These rates of comsumption supply adequate food to support the metabolism of the fish and probably account for the late summer-early fall decline in population levels ofMnemiopsis observed in Narragansett Bay.
