Resumen

This study analyzed field and acclimatized (7 days) mangrove Ucides cordatus crabs from polluted and unpolluted environments to compare their HSP70 levels. The animals were cryo-anesthetized and dissected. Gills (anterior and posterior) and hepatopancreas were collected to evaluate total proteins and HSP70 levels using ELISA (Enzyme-Linked Immunosorbent Assay) method. The acclimatized animals from polluted environments showed higher HSP70 levels in the hepatopancreas than field animals. Results showed higher HSP70 levels in laboratory animals from the polluted environment than in field animals in the posterior gills. The regulation to decrease the damage caused by the environment and the acclimatization process may not be sufficient to stabilize physiological responses, especially in animals from polluted environments.
