Descripción
This work focused on the effects on metabolism of environmental concentrations of endosulfan in the freshwater crabs Dilocarcinus pagei and Zilchiopsis collastinensis. The concentrations used were 0, 6 and 62 μg of endosulfan l-1. Oxygen consumption, oxyregulation capacity and critical oxygen concentration were modified by the presence of endosulfan in D. pagei. In contrast, Z. collastinensis crabs showed a decrease in the ammonia-N excretion rate, but the oxygen consumption was similar between exposed and control crabs. A significant increase in the O:N ratio was evidenced in Z. collastinensis exposed to this biocide, demonstrating a shift toward lipid and carbohydrate primary metabolism. Dilocarcinus pagei controlled its oxygen consumption through isolation as a defense mechanism, while Zilchiopsis collastinensis modified the ammonia excretion. These different defense mechanisms might be related to the dissimilar habitats that each species occupies.
