Abstract: ABSTRACT. Distribution, dominance and sizes structure of the fish assemblage in the Mangueira lake, southern Brazil. This study presents the composition of species, the distribution and dominance patterns, and the structure of sizes of the assemblage of fish in distinct habitats (littoral, deeper and near shore limnetic zone) of the Mangueira lake, in the southern Brazil. Samples were taken in the north, south and central regions of the lake from 2001 to 2007 using a multi-gear approach (gillnet, cast net, bea… Show more

“…Teixeira et al (2005) emphasize that the differences in physiography over a longitudinal gradient corresponded to the changes in the diversity and abundance of the fish assemblage, where species of Characiformes and Siluriformes have wide spatial distribution. The rarest species in the system were Trachelyopterus lucenai and Gymnotus pantherinus (0.004%), which corroborate data reported by Artioli et al (2009) in Mangueira Lagoon, Rio Grande do Sul state. Trachelyopterus lucenai is not considered a native species of the region, and might have come to the hydrographic basin through irrigation channels (rice fields) (Bertoletti et al 1992, Becker et al 2013.…”

“…BHAC also showed high species diversity compared to similar studies in aquatic systems. For example, in the coastal streams of austral Brazil, Bastos et al (2013) recorded a total of 41 species, while Artioli et al (2009) documented the occurrence of 52 species in Mangueira Lagoon, located in the same coastal plain, with the largest values comparable to those found in other aquatic environments in southern Brazil (Lucena et al 1994, Tagliani 1994, Malabarba et al 2009, Carvalho et al 2012. Lower numbers of species in the studies described above can be associated with the type of sampler, as well as lower environmental heterogeneity; however, the outstanding abundance of Characiformes and Siluriformes are documented for every location (Artioli et The downstream biotope presented the greatest richness, which may be related to increased diversity of habitats and micro habitats observed in this biotope, which corroborates the river continuum theory (Vannote et al 1980), where changes along the longitudinal gradient (upstream to downstream) tend to increase the biological diversity.…”

“…Using a combination of FO and PA, the items were rated on the following scale of relative importance (RI): 4 -abundant and frequent, 3 -abundant, 2 -frequent, 1 -present. Items classified as abundant and frequent were found to be dominant (ARTIOLI et al 2009). Subsequently, they were analyzed for temporal variation and between the sexes.…”

“…The relative importance (RI) of each prey category (i) (mollusks, crustaceans, insects, fishes, amphibians, reptiles, birds, mammals) was verified for each system by the rate of FO of such prey category over the sum of the frequency of occurrence of all prey categories: RI = (FO i /∑FO)x100. The RI values of each prey category were compared to the mean and the categories with values over the mean were considered frequent (Artioli et al 2009). The food niche breadth was calculated for each sampled system.…”
