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.

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.
General taxonomic coverage description: All specimens were identified to species level. The dataset included 39 marine species of fish, representative of half the best-known fish species from the Argentine continental shelf (55.7 %,

General spatial coverage: The Argentine continental shelf, in the Atlantic margin of South America (Figure
• The internal and external sectors of the shelf off the Province of Buenos Aires (35° S) to Patagonia (48° S).
• The southern part of the Patagonian-Fuegian shelf and Malvinas/Falkland Islands, along the outer shelf to the North, up to approximately 42° S.
• Deeper waters near the continental slope.
Coordinates: 52°S and 39°S Latitude; 65°W and 55°W Longitude.
Temporal coverage: May 11, 2001–June 26, 2001, July 21, 2001–August 31, 2001, January 11, 2002–February 27, 2002.
The sampling area was located on the Patagonian continental shelf (Figure
Specimens of fish and squid (commercial target and by catch) were taken daily by commercial fishing vessels operating with bottom trawls during autumn (May-June, 2001, 51 catches), winter (July-August, 2001, 38 catches) and summer (January-February, 2002, 112 catches). The fishing company provided the associated data of each fishing haul: date, hour, location (decimal Latitude and Longitude of the position while pulling the net) and depth of the catch (the maximum depth reached by the net). Specimens were frozen on board, and identified at species level at the Ichthyology laboratory of Centro Nacional Patagónico, Puerto Madryn, Argentina. The taxonomical identification of species was made by the specialists Dr A. Gosztonyi and Dr M. Re and the scientific names and their current accurate spelling were also reviewed using suitable literature (
Sex (when possible) and morphometric measures were taken for each specimen: wet mass (g) and wet mass of viscera (g, empty stomach); total and standard length (cm) for fish; mantle, head and fin length and width (cm) for squid; left and right fin length (cm) and maximum fin width (cm) for skates.
Step1: Sampling locality and depth were recorded in each season.
Step2: Specimens were sent to the lab for species and sex identification and morphometric measurements.
