Gonadal condition factor, hepatossomatic index and recruitment as indicators of reproductive period of Loricariichthys platymetopon (Osteichthyes, Loricariidae), Medium Uruguay river basin, South of Brazil

The recruitment period of Locariichthys platymetopon (Isbrucker & Nijssen, 1979) was investigated. It has been found out, through the data analysis, that the gonadal condition factor is a good indicator of the reproductive period and that the hepatossomatic index is probably related to the storage of reservation for the winter period. The recruitment occurred in November coinciding with the reproductive activity of May.
