“…While there has been, to date. no evidence of excessive harvesting in the offshore reefs, which are designated as "notake" zones, the coastal reefs appear to have been overfished (Ferreira and Gon~alves, 1999).…”

“…For example, herbivorous parrotfishes have been the target of spearfishing during the last two decades at many locations in Brazil (Ferreira and Gonçalves, 1999). An extreme case is the large rainbow parrotfish, Scarus guacamaia, that has probably been fished to ecological extinction in Brazil , as it has in many areas of the Caribbean (Mumby et al, 2004).…”

“…Are the endemic species threatened or impacted, and if so, what are the implications for managing this unique biogeographic region? Limited research suggests that both commercial and aquarium fisheries are taking large numbers of fish from Brazilian reefs, leading to significant changes in community structure (Costa et al, 2003;Gasparini et al, 2005), and both artisanal and commercial fisheries appear to be affecting the population size and size structure of fish populations (Ferreira and Gonçalves, 1999;Frédou, 2004;Gasparini et al, 2005). Other threats deriving from urban development and agricultural runoff along the Brazilian coast were reviewed by Leão & Dominguez (2000), although little is known about the effect of these threats to reef fishes.…”

The vast Brazilian coast harbors unique and diverse reef fish communities. Unfortunately, relatively little is known about the impact of fishing on these fish species, and few management or conservation efforts are being made to protect them. Here we examine the effect of different levels of protection on the composition, abundance, and size structure of reef fish species along a 2500 km portion of the Brazilian coastline, noting in particular the relative abundance of endemics and the effect of protection on these species. Pairwise comparisons of sites with different protection status (more versus less protected) were used to determine the potential responses of reef fishes to the establishment of marine protected areas. Highly targeted species (top predators and large herbivores) were significantly more abundant and larger in size within sites with a higher degree of protection, indicating that they benefit from protection, while lightly fished and unfished species were not. These results are consistent with past work documenting the responses of species to protection. Here, we use our results in particular to suggest strategies and provide expectations for managing and protecting Brazilian reef fisheries. Because this biogeographic province lies entirely within the jurisdiction of a single nation, there may be unique and significant opportunities to effectively manage and conserve these fish species.

“…Sparisoma é o gênero com maior quantidade de espécies nessa região (Bernardi et al, 2000;Streelman et al, 2002). Este gênero é ecologicamente diverso, apresentando uma extensa gama de formas alimentares e padrões de uso de hábitat (Bernardi et al, 2000;Streelman et al, 2002;Ferreira et al, 1999). Larvas de Scaridae não foram registradas em áreas estuarinas do nordeste brasileiro (Mafalda & Silva 1996;Ekau et al, 2001;Marcolin et al, 2010), indicando que ela crescem em zonas oceânicas e de plataforma.…”

Souza, C.S.; Barreiro, A. S. & Mafalda Jr., P. 2010. Spatial and temporal patterns of Scaridae larvae (Pisces: Perciformes) in the northeast of Brazil in relation to oceanographic conditions. Braz. J. Aquat. Sci. Technol. 14(2): 1-11. ISSN 1808-7035. This work had as objective to study the distribution and abundance of the Scaridae larvae and to analyze the influence of oceanographic conditions (temperature and salinity), on the space and temporal distribution of larvae. Ichthyoplankton was collected during expeditions: Period 1 (August -October 1995), Period 2 (January -April 1997), Period 3 ( April -July 1998) and Period 4 ( September -December 2000), realized in the Northeast Exclusive Economic Zone. One specie (Cryptotomus roseus) and one genus (Sparisoma sp.) were identified. Sparisoma sp. was the most abundant genus (94% of the total), with higher abundance during all Periods. Cryptotomus roseus was the less abundant specie, representing 6% of the total identified larvae. Cryptotomus roseus presented larger distribution with the maximum density during period 3, between Maceió and Aracajú. Sparisoma sp. larvae were found mainly in oceanic stations and near São Pedro and São Paulo Archipelago.
