Abstract

Abstract: Among the species with important potential in ornamental fish farming, Betta splendens has great relevance, as it is a fish widely spread throughout Brazil, standing out for its beauty, striking color and rusticity. In this context, the growing demand for ornamental species has induced increasingly intensive cultivation. Therefore, it is essential to produce diets that meet increasingly specific requirements of these animals, and the use of food additives for ornamental species can contribute to the production of rations, contributing to the strengthening of immunity, the intensification of coloration. corporal, increasing the digestibility of the ingredients, meeting the nutritional requirements of the species, in addition to collaborating with the well-being during cultivation. A good example is annatto, as it has bioactive compounds, such as carotenoids, from the secondary metabolism of plants, and with important antioxidant properties, responsible for cellular protection. In this context, understanding that the use of bioactive substances has increasing attention and use in commercial rations for their antioxidant action in cultivated animals, the objective of the present study is to evaluate the effects of different levels of inclusion of annatto extract in the diet of Bettas splendens, as a promoter of well-being during its cultivation.
