O Papel do monitoramento sanitário na produção aquícola

Abstract

Brazilian aquaculture is undergoing a great expansion, playing a significant role in food supply. However, the health issue becomes one of the main adversities to be considered. Thus, the performance of health monitoring becomes essential to identify and prevent the spread of diseases in production. That said, the present study aimed to assess cultivation conditions, management techniques, sanitary aspects of fish and properties throughout the cycle, making periodic visits for observation and assessments “in loco”. This work has been carried out for some years, accompanying pre-selected producers in the region of Dourados / MS. Initially, a dialogue was held with the producers involved, in order to obtain information about their management methods and techniques adopted, in addition to analyzing the structure of the property and subsidies. Soon after, the physical-chemical parameters of the water were measured, followed by collections of specimens of each species destined for commercialization, being evaluated externally for the presence of lesions, colorings, scales, mucus, and then followed by the internal analysis of the organs. “In situ”, fresh parasitological analyzes using microscopy, and after the samples obtained, they went on to evaluations at the Animal Morphophysiology Laboratory. Over the years, only routine pathogens of the genera: Trichodina, Monogenea, Ictio, Acanthocephali and Nematodes have been found, their quantity being insignificant to the development of the fish, located internally in the collected samples. A decrease in the occurrence of the aforementioned parasites can be observed, their presence being a reflection of the quality of the production environment. In this way, we can say that the action of this work provided these results, confirming the importance of permanent health monitoring in fish farms and good prophylaxis, preserving economic losses and ensuring safe consumption of fish.
