| Abstract: | The global tilapia industry has emerged as an important animal protein segment, with production estimated at 6.2 million tons, making it the second most cultivated fish in the world. In Brazil, production is estimated at 579 thousand tons in 2023, with a turnover of more than USD 1,2 billion. In the Distrito Federal (DF), tilapia production is estimated at approximately 1,800 tons per year, which is an important source of income for local farmers and serves as a source of protein for the consumer market in Brasília, the third largest in the country in terms of fish consumption. The general objective of this work was to characterize the commercial production of tilapia in the DF in terms of production, sanitary and epidemiological aspects. The thesis was subdivided into 5 chapters and annexes, with Chapter I consisting of an introduction and each of the other sections representing a paper that will be submitted to a specific scientific journal. Chapter II presents a literature review on tilapia disease surveillance and the sampling plans used in fish disease monitoring and epidemiological surveys. Chapter III deals with the production and sanitary characterization of commercial tilapia farming in the Distrito Federal between 2021 and 2022, based on a semi-structured questionnaire applied to 112 farmers. The results showed that tilapia farms in the DF generally have a good biosecurity, as 82.1% of the fish farms were classified as having a biosecurity level of B (low risk) or C (moderate risk) when assessing the degree of vulnerability to the introduction and spread of pathogens. This study also found significant differences (p<0.05) between some commercial strata, with the closed system fattening group standing out as having superior scores compared to the semi-closed system fattening, young form fish and pay-to-fish farms. Chapter IV presents the results of an epidemiological study using a survey model that included two complementary epidemiological components (a study based on targeted sampling and another on random sampling in an establishment at risk). It was found that the frequency of notifiable diseases in tilapia farms in the Distrito Federal is quite low. Chapter V evaluates the functionality of a monitoring and instant messaging system for smartphones as part of a surveillance program for notifiable fish diseases. This method proved to be superior to the traditional passive surveillance system and was able to detect the presence of a viral disease in the DF for the first time. |
