Dataset containing 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 and contains 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. / Conjunto de datos con 2007 registros morfometricos de 39 especies de peces y 2 especies de calamares de la plataforma y talud continental patagónicos. Este conjunto de datos describe una nueva versión de los datos originales publicados a través de OBIS y contiene datos de morfometría individual.Los especimenes representan organismos de hábitos pelágico, demersal, demersal-pelágico, demersal-bentónico y bentónico y fueron recolectados por barcos comerciales en otoño (Mayo-Junio 2001, 51 lances de captura), invierno (Julio-Agosto 2001, 38 lances de captura) y en verano (enero-febrero 2002, 112 lances de captura). El muestreo fue llevado a cabo con redes de arrastre a un rango de profundidad de 73-370 m. El área relevada se localizó entre 39° - 52° S y los 55° - 65° O.Sampling Description
Study Extent
The sampling area was located on the Patagonian Continental Shelf, in the Atlantic margin of South America, within -52 to -39 ºS and -65 to -55 ºW. The depth range of the sampling was 73-370 m.Sampling
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 and 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 Patagonico, 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 (Brunetti et al., 1998; Cousseau and Perrotta, 2013) and the WoRMS web site(http://www.marinespecies.org/). 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.Quality Control
--Method steps
- 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.

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 %, 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). Autumn and summer records presented a high diversity of species (80.5 and 78 %, respectively), while only 46% of the species were present in winter

Geographic Coverages
The argentine continental shelf, in the Atlantic margin of South America, is bounded by the line of the coast and the continental slope and is the most extensive submerged plain in the world, with an area of 930.000 km2 (Cousseau and Perrotta, 2013). It is characterized by gentle slopes and low-relief. The shelf waters are of sub-Antarctic origin diluted by continental flows and modified by exchanges of mass and heat with the atmosphere. The main distribution of the species of this dataset is:
• 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.
