4. Results of E.L. Holmberg 1997 fish survey in Subarea 48.3

   Abstract:  The survey comprised 51 bottom trawl hauls taken in subarea 48.3. Of these, one was ... discarded due to net damage. About 80% of the hauls were taken in the shelf of South Georgia Islands (41 ... ) and the remaining in the Shag Rocks area (9); 64% of the hauls were intended as replicates of the ... position of hauls in the previous cruises. Mean densities were obtained considering the spatial aggregation ...
