Abstract
The dataset contains 2007 records of occurrence of 39 species of fish and 2 species of squid distributed on the Patagonian continental shelf and slope. This dataset describes a new and revised version of the original data published through OBIS with individual morphometrics. Specimens are representative of pelagic, demersal, demersal-pelagic, demersal-benthic and benthic habits and they were collected by commercial fishing vessels in autumn (May–June, 2001, 51 catches), winter (July–August, 2001, 38 catches) and summer (January-February, 2002, 112 catches). The sampling was carried out with bottom trawls at a depth range of 73–370 m. The survey was located between 39°–52°S and 55°–65°W.
Highlights
The Patagonian continental shelf, in the Atlantic margin of South America, is characterized by a remarkable productivity accounted by its oceanographic and bathymetric features, promoting ‘hotspots’ of biodiversity and attracting marine top predators, such as sea birds and marine mammals
The dataset included 39 marine species of fish, representative of half the best-known fish species from the Argentine continental shelf (55.7 %, Cosseau and Perrota 2013), and 2 species of squid, that were captured during three seasons, autumn (May-June, 2001), winter (July-August, 2001) and summer (January–February, 2002)
The sampling area was located on the Patagonian continental shelf (Figure 2), within 52 to 39°S and 65 to 55°W
Summary
The Patagonian continental shelf, in the Atlantic margin of South America, is characterized by a remarkable productivity accounted by its oceanographic and bathymetric features, promoting ‘hotspots’ of biodiversity and attracting marine top predators, such as sea birds and marine mammals. The objective of this dataset is to provide basic information (location and depth capture, and individual morphometrics) of potential prey species of marine top predators from the Patagonian shelf, representative of pelagic, demersal, demersal-pelagic, demersal-benthic and benthic habits as useful information for ecological and biogeographical studies. Temporal coverage: May 11, 2001–June 26, 2001, July 21, 2001–August 31, 2001, January 11, 2002–February 27, 2002
