Summary

RMT hauls taken during FIBEX in the Prydz Bay region showed a relatively high incidence of fish compared with most previous reports from the Atlantic sector. Overall, fish comprised 3.8% by number and 8.1% by weight, and these figures rose to 26.8 and 46.1%, respectively in aimed hauls over the continental shelf. Even when only hauls with>50% E. superba are considered, fish accounted for almost 1% by weight of the catch overall, and more in aimed hauls or those taken over the continental shelf. Species composition differed markedly between the continental shelf and deep water zones. Over the shelf the fish catch comprised mainly Pleuragramma antarcticum and channichthyid juveniles, while over deep water it consisted mainly of myctophids and Notolepis coatsi. These data indicate that the potentially large krill fishery in this region could affect the populations of some shelf dwelling demersal species by increasing the mortality among their pelagic juvenile stages.
