Abstract
Abstract The macrozooplankton faunas were compared between two Newfoundland fjords containing predominantly different deep-water masses; Bay d'Espoir contains warm, saline, Modified Slope Water while Fortune Bay contains cold, low-salinity, Labrador Current Water. Samples were collected in May 1982 and June 1983 using a 3-m Isaacs-Kidd Midwater Trawl. Data are presented on the species composition, relative abundance and vertical distribution of macrozooplankton. The fauna in both fjords consisted largely of the euphausiids Thysanoessa raschii, Thysanoessa inermis, Meganyctiphanes norvegica and the chaetognath Sagitta elegans. Eleven species occurred only in Fortune Bay while nine species occured only in Bay d'Espoir. Twenty species were common to the fjord faunas although eight of these occurred in low numbers. Catch rates were significantly different between fjords for eight species, but not for four species including T. raschii the most abundant species in both fjords. Differences in species composition...
