“…When temperatures and salinity begin to decrease in autumn, the individuals start their migration to the reproduction grounds and leave the lagoons (D' INCAO, 1991; SANTANA andFABIANO, 1999); at this moment the fishery begins its activity throughout the autumn (March to May). presents great variability in recruitment, in which factors such as temperature, salinity, rainfall contribution and food availability (LEITE and PETRERE, 2006) and the influence of climate variability known as ENSO events, generate variations in the abundances of the species in its various habitats (MÖLLER et al, 2009; PEREIRA andD'INCAO, 2013). These variations are enhanced by the fishery of juveniles in coastal lagoons by small scale fisheries in Brazil and Uruguay (VALENTINI et al, 1991; FABIANO and SANTANA, 1999; D'INCAO, 2002; MÖLLER et al, 2009) and adults fisheries in the ocean by the Brazilian industrial fleet (VALENTINI et al, 1991;D'INCAO et al, 2002; LEITE andPETRERE, 2006).…”
