摘要: The demersal fish populations of the slopes Rockall Trough (250 to 3000m) have been sampled by a number different types trawl (Gordon & Duncan, 1985; Gordon, 1986). diets most species described (Mauchline 1980, 1983a,b, 1984a,b,c) and aspects trophic ecology discussed 1985, Rays were relatively uncommon in early sampling but more recent use Marinovitch semi-balloon with mud rollers chain on footrope has increased catches. This paper describes distribution diet 12 ray from Trough.
