Distribution and diet of Cyclothone microdon (Gonostomatidae) in a submarine canyon

摘要: The primarily bathypelagic gonostomatid Cyclothone microdon, amongst the most abundant of all vertebrates, remains poorly known. We describe its diet in Gully, a very large submarine canyon off Nova Scotia, Canada, based on stomach contents specimens caught by midwater trawl. In C. microdon had shallower distribution than open ocean and fed at mesopelagic depths. Most comprised vertically migrant calanoid copepods, while secondary prey was conchoeciinid ostracods. Both were typical food eaten other regions congeners consistent with results only previous dietary study microdon.
