Tecnologia de bioflocos: mitigação do canibalismo no dourado (Salminus brasiliensis) e maturação com mistura probiótica

Abstract

This thesis is structured into three chapters. Chapter 1 presents a literature review addressing the relevance of aquaculture, highlighting alternative farming systems, with emphasis on the BFT system and how it can influence water quality and the welfare of aquatic organisms. Additionally, it discusses the advantages of using probiotics in aquaculture, their benefits to animal health, their contribution to better nutrient utilization, and finally, the application of probiotic microorganisms in BFT to make farming more efficient and profitable. Another major challenge in aquaculture is cannibalism, which causes significant production losses and can be mitigated when fish are raised in BFT systems, reducing stress among animals. Chapter 2 presents an experiment conducted to evaluate the productive performance and survival of dorado (Salminus brasiliensis) in a biofloc system compared to a traditional system with partial water exchange. Chapter 3 investigated the development of microorganisms during biofloc formation, comparing a conventional system (BFT) with one using probiotics (BFTp).
