Avaliação sanitária de lambari Astyanax bimaculatus oriundos da piscicultura comercial de Dourados- MS

Abstract

Fish farming is seen as an important area in the Brazilian agribusiness sector because it is an economically profitable activity and because the country presents excellent climatic conditions and favorable resources for the activity. The lambari-do-rabo-amarelo Astyanax bimaculatus is a species well adapted to the semi-intensive production system. Forty-five commercial-sized fish of a Dourados-MS fish farm were evaluated for the presence of parasites in the gills and mucus. Of the total of 45 fish examined, all have a group of parasites in the gills and/or mucus. 43 fish (95.6%) were parasitized in the mucus and 38 (84.4%) in the gills. Still, 36 fish (80%) had parasites concomitantly in the two sites that can be found in large numbers of parasites, as well as the environment and animal conditions, being pathogenic and beneficial to the producers. The main groups of parasites that appeared were Trichodina, Ichthtyophthirius, Henneguya and monogenes. Thus, to avoid epizootics that could disturb the production, the production of this fish needs to be better understood and technically monitored.
