Resumen:
There are increasing global concerns of the alarming pollution impacts on marine life, thus it is becoming essentialto generate reliable tools to monitor and understand the effects of these impacts on aquatic organisms. Weperformed a field study assessing how exposure to anthropogenic pollution impacts immunological andhealth-state parameters and parasite infection of awild marine fish, the Brazilian sandperch Pinguipes brasilianus.Thenwe compared this information to previously published data of a sympatric species, the Patagonian rockfishSebastes oculatus inhabiting the same polluted and pristine areas. The field study revealed that exposedP. brasilianus showed chronic stress, poor immune condition and higher prevalence and abundance of acanthocephalanparasites. By comparing these former results with already published in S. oculatus, we concludedthat, although both species exhibited physiological alterations associate to inhabiting sites exposed to pollution,their specific immunological and health-state responses differed. Our results demonstrate that Patagonian reeffishassemblages inhabiting sites exposed to pollutant are being affected in their immune and heath condition,which could potentially result in higher susceptibility to disease and in turn population decline. These findingshighlight the necessity of more studies incorporating interspecific comparisons to assess variation in fish
