EFFECTS OF ANTIBIOTICOTHERAPY ON TAMBAQUI (Colossoma macropomum): FLORFENICOL AND OXITETRACYCLINE IN AMAZONIAN AQUACULTURE
Antibiotic therapy, gills, liver, intestine; food security.
Animal husbandry is an essential activity in Brazilian agribusiness, where antibiotics are widely used to guarantee productivity and competitiveness, with fish being a significant group due to their diversity. While extractive fishing is unpredictable, aquaculture allows greater control over production, being crucial for food security, especially in the Amazon. This study focuses on antibiotic therapy with florfenicol (FLO) and oxytetracycline (OTC) in tambaqui (Colossoma macropomum), evaluating their histopathological effects on gills, liver and kidney, and isolating intestinal bacteria. One hundred tambaquis, divided into five groups with different dosages of FLO and OTC, will be analyzed. The research aims to contribute to knowledge in fish microbiology and promote sustainable strategies in aquaculture, balancing productivity and environmental conservation
