| Abstract: We introduce the work providing a synthetic description of the diversity and phyletic structure of freshwater fish in the Neotropical Region, especially emphasizing that of Brazil. This is accompanied by a discussion about environments of fish from small to medium sized to large, taking into account how it shaped their respective biologies/ecologies, as well as what they imply for their use by humans. We present, as figures, the results of our exploratory analysis of Brazilian Red Book of Threatened Species of Fauna (2018), focusing on the small-sized ones, with up to 15 cm of standard length. We continue to present the main human impacts in small fish environments, along with those suffered by medium to large fish environments, and then follow... |

| This communication deals with the sexual colour patterns in the sandperch Pseudopercis numida Ribeiro, 1903, a benthonic fish of commercial importance, endemic to the Brazilian continental shelf, occurring off the coasts from Espírito Santo to Rio Grande do Sul States. The males have the head, the dorsal part of the body, and the pectoral and caudal fins blackishes, whereas the females have them brown-yellowishes. Such patterns are constant characters, not related to maturity or breeding seasons. |

| The tilefish, Lopholatihis villarii Ribeiro, 1915 is a commercially-important demersal fish, in the Southeast Brazil, inhabiting calcareous and rocky substrates of the outer shelf and upper continental slope. This study was based on readings of the scale's age rings of 153 especimens, caught from March, 1995 to March, 1996. Scales were found to grow on an isometric proportion with fish length, and age rings are formed betvveen the third and fourth trimesters (winter and spring). The age groups of sampled fish varied from II to X years, and the growth equation in total length (cm) is Lt = I 13.4 [1-e -0.144 (t+ 1.4)] w ith the correspondem one in weight (kg): W, = 22.5[1-e -0.144 (1 + 14)]3 184 obtained from the weight/length regression equation: ln W =... |
