Hábitats esenciales de condrictios (Chondrichthyes) costeros, y su relación con los procesos oceanográficos
MetadataShow full item record
The relationship between environmental variables (depth, temperature and salinity) and the abundance of sharks (Mustelus schmitti and Squatina guggenheim) and skates (Sympterygia bonapartii, Rioraja agassizi and Atlantoraja castelnaui) was analyzed in the Southwestern Atlantic coastal waters (between 34~'S and 42~'S at depths of less than 50 m from the coast line). Data were collected during research Cruises carried out by the National Institute of Fisheries Research and Development (INIDEP) during winter and late spring. Due to differences in the continental water discharges, salinity spatial distribution and in the environmental condition seasonality, data from the Río de la Plata and El Rincón were independently analyzed. Shark and skate species shows different relationships with the environmental variables, showing differences in the spatial distribution patterns and in the abundance seasonality between species. M. schmitti and S. guggenheim showed ontogenetic differences in the h.....
