Abstract
Fish farming is a promising activity in the Western Amazon. The tambaqui (Colossoma macropomum) stands out for its good zootechnical performance, supply of fingerlings, rusticity and consumer market, being the most cultivated species (90% of all production) and consumed in Roraima. Like all confined animal production, there is a risk of pathogens and diseases emerging. The tambaqui can be affected by a wide variety of parasites, bringing irreversible damage both economically and healthily. The objective of this study was to identify and quantify parasites present in gills, intestine and tambaqui muscle from five fish farms in Rorainópolis-RR, as well as to correlate results with biometric variables and to estimate parasite prevalence and abundance. For this, 25 tambaqui specimens were acquired in five fish farms in the municipality of Rorainópolis-RR. Parasites of the class Monogenea (Girodactilideo sp.), Phylum Nematoda (Procamallanus (Spirocamallanus sp.) and Klossinemella sp.) and the class Myxozoa (Myxobolus sp.) were recorded . In two farms there was a 100% prevalence of infestation by Monogenea. The standard weight-length ratio curve (y=0.01x3.27 (R2=0.84)) was calculated, where the relative condition factor between parasitized and non-parasitized individuals was calculated, whose values did not differ statistically (p=1) by the Mann Whitney 'U' test. In this sense, it is important to properly manage and maintain the sanitary status of tambaqui production in the southern region of Roraima.
