“…Fish density according to vertical position, feeding habits and ontogenetic stages presented the same pattern, suggesting the shelter influence on structure and composition of the local fish assemblage. Also, in artificial reef environments Charbonnel et al (2002), Sherman et al (2002) and Kawasaki et al (2003) related higher fish density and richness to higher structural complexity habitats. Eklund (1997) in a similar experiment with fish assemblages at artificial reefs observed that fish density and richness did not differ between modules with and without benthos in opposition to those complex and non-complex.…”

Stationary visual census surveys were performed on an experimental artificial reef (21º29'S, 41º00'W) to clarify the role of structural complexity and benthic community as fish community modeling agents. Concrete modules of four types were grouped according to the combination of structural complexity through the presence/absence of holes and favourable/unfavourable surface for benthic colonization by anti-fouling painting. The survey (December 2002 to March 2003) showed higher abundance, richness and diversity in the complex modules. The same habitat usage pattern was observed according to vertical position and bottom type categories: demersal, hard-bottom and habitat generalist fishes preferred the complex ones. A higher number of juveniles occurred at those modules. It is assumed that trophic relationships and different habitat selection related to ontogenetic stages are also important modeling agents to the fish community structure since juvenile fish seem to actively seek the experimental complex modules.
Censos visuais estacionários foram realizados em um recife artificial (21º29'S, 41º00'W) para determinar o papel da complexidade estrutural e da comunidade bêntica como agentes modeladores da comunidade íctica. Módulos de concreto foram agrupados de acordo com a combinação do fator complexidade estrutural através da presença/ausência de cavidades internas nos módulos e de superfícies favoráveis/desfavoráveis à colonização da comunidade bêntica através de tinta anti-incrustante. De dezembro de 2002 a março de 2003, foram registrados maiores valores de abundância, riqueza e diversidade nos módulos complexos. Padrões de uso de habitat similares foram observados de acordo com a posição vertical na coluna de água e tipo de fundo: peixes demersais, de fundo consolidado e habitat generalista preferiram módulos complexos. Os resultados indicam que relações tróficas e seleção de habitat relacionada ao estágio ontogenético são também importantes agentes modeladores da comunidade íctica, uma vez que peixes juvenis buscam ativamente os módulos experimentais estruturalmente mais complexos

“…This is especially true of designed artificial reefs, which, unlike materials of opportunity (Seaman et al 1989), are built and deployed to achieve specific environmental objectives (Pickering & Whitmarsh 1997, Baine 2001. Artificial reefs are popular fisheries enhancement tools because fish biomass often increases in surrounding waters after their deployment (Bombace et al 1994, Charbonnel et al 2002, Leitão 2013. Whether increases in fish biomass involve new production or simply attraction of existing biomass is debated (Bohnsack 1989, Grossman et al 1997ABSTRACT: Artificial reefs continue to be deployed in coastal areas to enhance local fisheries.…”

“…ers et al 2003ers et al , Brickhill et al 2005. It is generally agreed, however, that artificial reefs can provide habitat space and food resources for fishes , Cresson et al 2014, and it is this provision of refuge and food that is most likely to drive any production of fish biomass on these reefs (Charbonnel et al 2002. Thus, quantitative research is needed to explore how artificial reefs influence fish production via these factors.…”

“…Habitats with high structural complexity usually support more species and individuals by providing shelter and refuge against predation and competition (Holt, 1987;Greenberg et al, 1995;Beukers & Jones, 1997;Connel, 1997;Charbonnel et al, 2002;Gratwicke & Speight, 2005). Complexity appears to have a marked influence on abundance of territorial and sedentary fish species, such as damselfishes (Pomacentridae) and groupers (Serranidae) (Sale & Douglas, 1984).…”

We provide here the first assessment of the composition, abundance and distribution of rocky reef fishes of Itaipu Sound, Rio de Janeiro, off the southeastern Brazilian coast. Monthly visual censuses, benthic quadrats and chain link transects were conducted over one year on rocky reefs at three islands (Menina, Mãe and Pai). A total of 2466 individual fish, belonging to 29 families and 42 species were recorded. The most abundant fish species were Parablennius pilicornis, Haemulon steindachneri, Orthopristis ruber and Diplodus argenteus. Sheltered and complex habitats showed the most abundant and diverse fish populations. There was a major significant separation between sampling sites and a secondary seasonal pattern. The three sites showed similar fish communities with locally structured environmental gradients according to their inherent habitat characteristics.Apresentamos aqui o primeiro estudo da composição, abundância e distribuição de peixes recifais nos recifes rochosos da enseada de Itaipu, Rio de Janeiro, Brasil. Foram realizados mensalmente censos visuais, quadrats de composição bentônica e transectos com correntes durante um ano em recifes rochosos de três ilhas (Menina, Mãe e Pai). Um total de 2466 peixes pertencentes a 29 famílias e 42 espécies foi registrado. Os peixes mais abundantes foram Parablennius pilicornis, Haemulon steindachneri, Orthopristis ruber e Diplodus argenteus. Os recifes mais abrigados e com maior complexidade de hábitats foram os que apresentaram maior abundância e diversidade de espécies. Análises estatísticas revelaram distinções significativas entre as áreas amostradas e um padrão sazonal secundário. As três áreas apresentaram basicamente a mesma comunidade de peixes, estruturadas a partir de gradientes ambientais e de características estruturais próprias de cada ilha.
