Fishing in Buenos Aires
The lagoons of the Pampas plains, most of them located in the Province of Buenos Aires, south of Santa Fe and Córdoba, resemble those of the litoral rivers region because they share specimen from the neo-tropical or Brazilian ichthyofauna. However, the region has particular ecologic, functional and fishing characteristics that deserve considering it separately.
Rivers, in the rainy season, burst their banks producing huge floods but, at the same time, feeding a lot of lagoons of the area. Near the sea, the ichthyofauna is more diverse and there is a strong interchange with species of the Río de la Plata's Delta.
The Salado river constitutes an access corridor for the Lisa (Stripped Mullet). Sea catfish, anchovies, sea kingfish and true soles can also be found, though less frequently. Of occasional presence, and most related to the Río de la Plata, is the chafalote, yellow catfish, porteñito and blackfin pati. Notwithstanding the above, the predominant fish is the kingfish, highly appreciated by the fisherman of both the city and province of Buenos Aires. Another fish that shares the habitat of the kingfish is the tararira (Hoplias malabaricus), a very voracious predator.
For fly fishermen that use ultra-light equipments, there are other varieties of small but very combative fishes like Dientudos and Chanchitas and a great quantity of Tetras and Mojarras. The Common Carp is a variety that was aggressively introduced in the lagoons, which has become a real concern because of the possible environmental damage due to its feeding way which consists in digging up the bottom thus uprooting the aquatic vegetation and removing the soil nutrients.
