FISH PARASITES AS A BIOLOGICAL BIOMARKER: A HIDDEN BIODIVERSITY
((fish*)), ((parasites*)), ((Brazil*)) and ((biodiversity*))
Parasitism is commonly exclusively associated with its harm to the host. However, the parasite-host relationship has shown great ecological importance as a tool for environmental investigation. The general objective of the present work is to use ichthyo parasitology as an environmental biological biomarker. The present study was divided into four chapters, the first a systematic review on the subject, the second chapter a study of ectoparasites in the native ichthyofauna of the Araguaia River basin in Cocalinho/MT, the third chapter investigating the impact of the use of probiotics in food supplementation in fish farms and, finally, the fourth chapter the analysis of fish parasites in different environments. The results of each of the studies, with their specific particularities, may contribute to a new perspective on ichthyo parasites to develop the characterization of fish parasites in their ecological concepts, such as information on the abiotic and biotic factors of the environments studied
