The result was the establishment of six sampling stations (P01… P06) which are influenced by recreational, urban activities, liquid discharges from a local banana, among others. A total of 8 species of ichthyofauna were identified; being the most and least representative (Moenkhausia sp (bongo) and Hoplias microlepis (guanchiche), respectively). The Shannon Wiener index calculated for the stations ranged between 0.76 and 0.67, indicating a low diversity. The omnivorous species were found more frequently; especially at the P03 sampling station (95%). Five stations (P01, P02, P04, P05 and P06) had poor water quality and the station (P03) presented a very poor IBI; which allows to accept the idea raised. |
