abstract
A combined hydroacoustic and midwater trawling survey of the Prince Edward Island Group was completed in May-June 1980. The area was characterised by relatively low zooplankton abundance and biomass (0,001 - 2,625 mg dry weight/m3), thought to be the result of seasonal variation. Dominant species found were Parathemisto gaudichaudii, Sagitta gazellae and Gaimardia trapesina. Both P. gaudichaudii and S. gazellae along with Euphausia vallentini were implicated in the diets of island-based predators in the region.
