| Resident fishes and their seasonal use of a surf zone were characterized and identified in the Jaguaribe beach, located on the Island of Itamaracá, state of Pernambuco, northeastern Brazil. Monthly towings (March 2006 to February 2007) with a beach seine net (20 m long, 1.5 m high, 5 mm mesh size) in different moon phases and periods of the day (day and night) were conducted. A total of 6,407 specimens, 35 families and 90 species were recorded. Seven species were considered as annual residents (Anchoa tricolor, Anchoviella lepidentostole, Bairdiella ronchus,Larimus breviceps, Lycengraulis grossidens, Polydactylus virginicus and Pomadasys corvinaeformis), three resident throughout the dry season (Conodon nobilis, Lile piquitinga andMenticirrhus americanus)... |

| Fish assemblages are an important element of sandy beaches, as they are fundamental for these ecosystems' balance of energy. Descriptions of the structure of fish assemblages in the sandy beaches of northeastern Brazil are scarce; this is especially true for the state of Rio Grande do Norte, which northern coast is poorly studied. This study aimed to identify the fish fauna of São Cristóvão Beach and to determine their assemblage structure. Three trawlings, considered as replicates, were undertaken monthly, in the same day, during 10 minutes each time, parallel to the coastal line, and in the direction of current, from February 2010 to January 2011. To describe the general pattern of the fish assemblage, the abundance, frequency and trophic categories of... |

| ABSTRACT For the demersal fish that inhabit sandy beaches, the variation between day and night periods represents a determinant factor in their behavior, especially for species that live in shallow waters. This research aims at determining whether there are differences in the fish assemblage structure of the sandy beach of São Cristóvão, RN, Brazil, between diurnal and nocturnal periods. Samplings were carried out in 2011, during spring high tide period, with an otter trawl net. Dissimilarity between diurnal and nocturnal fish assemblages was confirmed by PERMANOVA results. No statistical differences were observed for richness and diversity of fish assemblage between day and night periods. The first and third order carnivores were the significantly more... |
