    Ichthyofauna Structure at Risk due to the Bio Invasion of Clarias gariepinus in a River at Guapimirim Environmental Protection Area, Southeastern Brazil
    Author(s): Michelle Torres Dumith* and Alejandra FGN Santos

    The African sharp tooth catfish (Clarias gariepinus) is the most important catfish species for aquaculture. It has a great capacity to endure several stressing factors, such as adverse environmental conditions, besides having broad feeding flexibility. Notwithstanding, the presence of this alien fish species in the Guapimirim Environmental Protection Area, in southeast Brazil, may have negative impacts on the community of native fish. In 2018, during dry and rainy seasons, samples from the fish community were collected in 32 sites of the Guapi-Macacu River, in addition to abiotic variables (salinity, pH, temperature, turbidity, dissolved oxygen, and transparency) to diagnose which factors influence the distribution of the alien fish along the river. Moreover, species were evaluated as bio indicators in the ichthyofauna to identify potential alterations in the commu.. Read More»
