Uso do extrato de maracujá passifloraceae na dieta para oreochromis niloticus

Abstract

Aquaculture is one of the most prominent sectors within aquaculture in Brazil. Tilapia farming has been growing at rates above 10% per year, possibly due to the species’ ease of handling, good adaptability to adverse environmental conditions, and high acceptance of formulated diets, which results in excellent feed conversion and weight gain rates. The search for alternative feed ingredients to reduce production costs should be one of the key strategies in fish farming, aiming to achieve profitability and maintain the organoleptic quality of the fish. One ingredient that has been gaining attention is passion fruit, as it offers anti-stress properties and contains biochemical characteristics suitable to meet the nutritional needs of fish. Therefore, the objective of this study was to evaluate the feed intake and feed conversion of Nile tilapia (Oreochromis niloticus) fed a diet supplemented with passion fruit extract.
