Abstract:Juvenile freshwater dourados (Salminus brasiliensis Cuvier) were stocked in two batches of different size (61 and 133 individuals) with a time lag of 41 days in the headwaters of the Sinos River.

O nível alto de movimentos na situação de maior densidade é visto como resultado da competi… Show more
