Some notes on shoaling behavior and growth of Mysis gaspensis (Mysidacea) in a small Newfoundland estuary

Abstract

Mysis gaspensis habitually concentrated in a zone of medium current (12–40 cm/s) and low salinity (1.0–4.0‰) along one bank of a small estuary during low tide. Population size for the estuary was estimated at 38 000 animals (0.1 mysid/m2). Growth of M. gaspensis was about 3 mm during July, and this species apparently has a 2-year life cycle.
