Caracterização molecular de mixosporídeos isolados de peixes em sua fase inicial de criação

Abstract

Brazilian fish farms have grown in recent years due to the farming of fish of commercial interest, such as hybrid catfish derived from a cross between two species, (Pseudoplatystoma reticulatum ♀ and Pseudoplatystoma corruscans ♂), known as fertile hybrid. The fish farmers employ inadequate sanitations practices, which favor the emergence of parasitic diseases. These are considered the main causes of the high mortality rates of fish. The parasites frequently identified in these fish are from the Myxosporean family, among them Henneguya and Myxobolus genera. The identification of parasites present in fish farming contributes to the creation of new management techniques aimed at improving health indicators. Fish farming in the Midwest is one of the most important in Brazil. However, there are few studies that identify parasites in these farms. This study aimed to characterize through molecular techniques parasites isolated from farmed fish in Mato Grosso do Sul. This study will help to establish new management techniques, contributing to the reduction of parasitic diseases in fish farms and consequently, the reduction of mortality in these animals.
