[Methodology for assessing the potential and the depredating capacity of larvivorous fish by direct observations in the laboratory].

Based on practical experiences, it was presented the way to assess the potential and the depredating capacity of mosquito larvae by direct observations in the laboratory, using fish. The objective is to facilitate a methodology that allows to know about the behavior of those vertebrates in the presence of the immature stages of the hematophagous diptera in different water bodies.
