    Abstract

    Scientific observation on the species composition and abundance of fishes incidentally caught during Antarctic krill (Euphausia superba DANA) fisheries by F/V Niitaka Maru (5200t) were made from 6 August to 30 August to the north of South Georgia Is. Among 87 net hauls quantitatively examined, by-catch fish was recognized in 26 trawl catches (29.9%) and only one fish was found as by-catch in 21 hauls. Among a total of 7 fish species, Myctophidae 3, Zoarcidae 1, Nototheniidae 1 and Channichthyidae 2, recognized, Krefftichthys anderssoni of Myctophidae occurred most frequently (38.5% of net hauls containing by-catch fish). Owing to the small amount of by-catch, no clear relationships between krill CPUE and fish by-catch could be confirmed in the present study.
