List of the ichthyofauna in the Sontecomapan lagoon, Veracruz Mexico

Abstract

The aim of this study was to determine the ictic biodiversity in the lagoon Sontecomapan, Veracruz, Mexico and its space-temporal changes. Seventeen sampling points were selected using a stratified sampling for the dry and rainy seasons of 2005 and the dry season of 2006. Fishes in larval, juvenile and adult stage were obtained for each season. For the capture of larvae and juvenile, a dragging was carried out over the submerged vegetation using a Renfro net of 700 μ; the adult fish were obtained using a rowing-boat about 30 m long and 2 m high, with a mesh light of ¼ inch. Generally, the lagoon presented a mean depth of 166.57 cm, with a maximum of 650 cm and a minimum of 60 cm. Are present the physicochemical parameters for the dry season of 2005, the rainy season of 2005 and the dry season of 2006. It can be concluded that in the Sontecomapan lagoon live 52 species belonging to 24 families and 41 genus. The list of the ichthyofauna in the Sontecomapan Lagoon, Veracruz, Mexico is shown.
