Demersal groundfish assemblages and depth-related trends on Flemish Cap (NAFO division 3M): 2004–2013
We examine groundfish assemblage structure and diversity in relation to depth on the Flemish Cap using data from a multispecies bottom trawl survey performed by the EU. The data include 1699 hauls prosecuted between 129 and 1460 m and collected from 2004 to 2013. We focused on the 29 most abundant s...
