Abstract

In this study presentation is made of the information on specific richness and composition of the benthic community associated to Patagonian scallop fishery obtained analyzing the data derived from research and stock assessment cruises carried out in the 1995-2013 period in the zone named as Management Unit B. The area was studied and assessed with dredges and commercial trawl nets. The results obtained suggest that the richness range per station would be higher in the years in which samplings of the benthic community derived from catches performed with dredge, gear that would allow a better estimate of species richness per site. A larger number per sample and a better representation of the less significant and smallest ones was detected.
