Estudi de les interaccions entre les espècies íctiques introduïdes i autòctones al llac de Banyoles (Girona)

The introduction of exotic species has deeply altered the Banyoles lake's ichthic community. Interaction between these species and the four still-subsisting species in the lake will be the subject of our analysis. Its main objects are reproduction ecology, habitat usage and space-time distribution; and ecosondage, electrical and net fishing and telemetry are the various techniques to be utilized. It is in this way that the introduced species' mechanisms provoking the autochthonous specie's regression and extinction will be determined.
