Dj. Jellyman, DIET OF LONGFINNED EELS, ANGUILLA-DIEFFENBACHII, IN LAKE-ROTOITI, NELSON LAKES, NEW-ZEALAND, New Zealand Journal of Marine and Freshwater Research, 30(3), 1996, pp. 365-369
The diet of 72 longfinned eels, Anguilla dieffenbachii, from Lake Roto
iti, Nelson Lakes National Park, New Zealand, was numerically dominate
d by snails, especially Lymnaea. Larvae of the dragonfly, Procordulia
grayi, were extensively eaten as they migrated towards the shore for e
mergence. By weight, the most important food was fish, with upland bul
lies, Gobiomorphus breviceps, most important for eels < 500 mm, and ye
arling brown trout, Salmo trutta, for eels > 700 mm.
