Ichthyological and limnological observations on the Sali river basin (Tucumán, Argentina)

The ichthyofauna of the Sali river basin, Tucuman, Central Argentina is analyzed. Twenty three species and two subspecies were collected, of which nine species and one subspecies are new for the Sali river basin: Cheirodon interruptus, Odontostilbe microcephala, Cyphocharax cf. modestus, Jobertina r...
