Abstract

Currently, aquaculture is the animal food production with the fastest growth in the world. Due to Brazil's extensive freshwater reserves and favorable climates, there are great expectations for the aquaculture sector. Today Brazil is the second largest producer in Latin America and the seventh largest producer of tilapia. However, the practice of intensive aquaculture provides stressful conditions and risk of injury to the animals, which can increase susceptibility to the occurrence of pathogens. Infectious diseases are a major concern because they represent risk to production, affecting productivity. The use of veterinary medicines in productive sector is useful to prevent and treat diseases. However, there are only a few drugs regulated in Brazil that are approved in aquaculture, because of the lack of alternative veterinary medicines and the high cost of drugs available, there is a suspicion that the fish farmers are making use of irregular prescription, or even of banned substances. This practice can lead to possible presence of residues of these substances in animal food, endangering the food safety for consumers. The Albendazole is a broad-spectrum antiparasitic used to treat helminthic parasites in the intestinal tract, widely used in the veterinary field for cattle, sheep and goats, and it has proven to be effective in fish such as tilapia and tambaqui, however it is not regulated for fish farming. The goal of this project is to estimate the grace period of albendazole and its metabolites, by residual depletion test in tambaqui and tilapia (exotic), two very important species of fish that are commercialized in Brazil. From these studies, we will evaluate differences in clearance rates of both species, which have different levels of lipids in the body composition that may interfere with the residual depletion of drugs.
