Abstract
The mysids occurring in the stomachs of cod (Gadus morhua Linnaeus, 1758) taken in winter, spring, and autumn of 1982 and 1983 in the shelf area south and west of Iceland have been examined. Eleven species but only 55 individuals were found in the 1448 stomachs containing food, which were analysed. Mysis mixta Lilljeborg, 1852, which occurred at one station, amounted to 42% of the mysids found in the cod stomachs. The other species were, in declining numbers of abundance, Meterythrops robusta S.I. Smith, 1879; Mysideis insignis (G.O. Sars, 1864); Amblyops abbreviata (G.O. Sars, 1869); Parerythrops obesa (G.O Sars, 1864); Stilomysis grandis (Goës, 1863); Boreomysis nobilis G.O. Sars, 1885 Gnathophausia zoea Willemoes-Suhm, 1875; Boreomysis microps G.O. Sars, 1883 Mysidopsis didelphys (Norman, 1863), and Schistomysis ornata (G.O. Sars, 1864). Of the last four species only one individual was found. M. mixta, M. robusta, S. grandis, and B. nobilis have previously been found in cod stomachs sampled in subarctic waters off north and east Iceland while the other species appear to be confined to the warmer waters off the south and west coasts.
