Aragua/no -Tocantins, Brazil."eatrícle.macíelssembrace.brIntroduction / AimThe pirarucu, Arapaima gigas, is a Brazilian native fish with great aquaculture potential, due to its rusticity, high growthrates and market acceptance.However, the lack of knowledge of breeding in captivity results ininsufficient fingerlings supply and high market value.Moreover, high incidence of mortality is observed after parentalcare separation and during the initiallaboratory farming, where theyare kept for feeding training (Figure 1). Records relate mortalities tothe occurrence of parasites and opportunistic bacteria. Although thediagnosis is not always realized, protozoa and metazoanectoparasites of high pathogenicity are often foundin in this species,considering those conditions. (Figure 2).Aiming to deepen the scientific knowledge on health aspects ofpirarucu, and attempting to improve the fingerlings survival rates apartnership was signed between SEBRAE and EMBRAPA, incollaboration with the UFT.MethodsThis agreement will implement actions in three lines:® Parasitology, which will study relations between A. gigasparasitism and water quality;® Disease prevention, which will evaluate methodologies toenhance fish immune response;® Diseases treatments, which will be evaluated parasitic infections'treatments in specific farming systems.Figure 1 - Pirarucu parenta! carebefore separation.
