GOOD AGRICULTURAL PRACTICES IN THE PRODUCTION OF NILE TILAPIA (OREOCHROMIS NILOTICUS) IN A SIMPLE RECIRCULATION SYSTEM IN URBANIZED AREAS

Abstract

The growth of Brazilian fish farming was due to the considerable increase in fish consumption, especially tilapia, which continues to be the most produced fish in the country, representing 65.3% of the total national aquaculture production. What was necessary was the search for  the application of good agricultural practices in the production of Nile tilapia in alternative systems that produce with high density and work to reduce waste discarded in the tributaries. Thus, the study examines the implementation of biosecurity measures in simple recirculation systems, which through the biofilter reuses the same water during cultivation. These measures are necessary to ensure the health and well-being of the fish, as well as food safety. Based on a comprehensive literature review and field research, recommended practices for the installation and operation of these systems are analyzed, including the selection of suitable locations for solar incidence control, the performance of quarantine periods for monitoring clinical signs in fish lots, the regular clinical evaluation of fish,  the continuous monitoring of water quality, the implementation of good management practices and the responsible use of medicines, when necessary. The results highlight the importance of these practices to prevent the introduction and spread of pathogens, as well as to promote the sustainability and economic viability of aquaculture production in urbanized environments. The dissertation contributes to the advancement of knowledge in the area and provides practical guidelines for producers and managers of Nile tilapia production systems in urban areas.
