RESUMO:
This study aimed to verify the effect of space-time on the composition and structure of the ichthyofauna in an urban stretch of the river Apodi/Mossoró, RN. For this, community knowledge (richness, diversity and abundance) and abiotic data were used. 7 samples of abiotic data and 6 samples of points were made in urban sections of the Passage community of Pedras, where the river is fragmented in two points of construction of passages The collection was done in 3 different points: the first point further upstream of the first pass, a second point between passes and a third point downstream of the second pass. For the collection, multiparameter devices and a cast net were used. There were 396 people, divided into 11 people, 9 families and 5 orders. The diversity, richness and evenness indices were presented in relation to time and space. There was a difference in the values of these indices depending on the sampling points and the collection period. The amount of richness was higher in the rainy season, with significant importance from point 1 to point 3, as well as richness. As for similarity, it was observed that points 1 and 2 are more similar and point 3 is further away. Salinity also increased in the direction – upstream - downstream, being lower in P1 and higher in P3. Considering the occurrence of species for the Apodi/Mossoró river, 5 were outstanding, 2 were accessory and 4 were occasional.
