Functional role of fouling community on an artificial reef at the northern coast of Rio de Janeiro State, Brazil

Abstracts

The northern coast of Rio de Janeiro State lacks natural consolidate substrates, making it a proper environment to the development of researches using artificial structures. After studies about the type of substrate, concrete seems to be the most appropriate for studying fouling community development. This research was carried out to investigate the functional role of biofouling in the development of the ichthyic community in the north of Rio de Janeiro State. Percentage data of the epibenthic organisms' coverage and samples of the fish community with gillnet and visual census showed that biofouling in artificial reefs might have more than one functional role, acting as a facilitator in the recruitment of fish species and as a link in the trophic marine chain. Through the increase of localized structural complexity provided by the reef itself and by the fouling organisms which act as "engineering species", additional protection options are offered to the ichthyic community, especially recruits. Also, the epibiont biomass represents an important link in the food web, acting either as a direct source or in the transference of energy to higher trophic levels. Through the relationship between the ichthyic and fouling communities we concluded that the functional role of the latter in artificial reef habitats could be characterized mainly as shelter and feeding grounds for few fish species.

O litoral norte do Estado do Rio de Janeiro possui uma escassez de substrato consolidado natural tornando o ambiente propício para o desenvolvimento de pesquisas com estruturas artificiais. Após estudos conclusivos sobre o tipo de substrato, o concreto parece ser o mais apropriado para o desenvolvimento da comunidade incrustante. Novas pesquisas foram realizadas para investigar o papel funcional da bioincrustação no desenvolvimento da comunidade íctica no norte do Estado do Rio de Janeiro. Dados de porcentagem de cobertura dos organismos epibênticos e amostragens da comunidade nectônica com rede de espera e censo visual, evidenciaram que a bioincrustação em recifes artificiais pode assumir mais de um papel funcional, como facilitadora no recrutamento de espécies de peixes e como elo na cadeia trófica marinha. Através do incremento da complexidade estrutural fornecida pelo próprio recife e pelos organismos incrustantes que atuam como "espécies engenheiras", opções adicionais de proteção são oferecidas para a comunidade íctica, principalmente recrutas. Além disso, a biomassa epibionte representa um importante elo na cadeia alimentar, atuando como fonte direta de alimento e/ou transferência de energia para níveis tróficos superiores. Através da relação entre as comunidades íctica e incrustante, conclui-se que o papel funcional desta última em habitats recifais artificiais caracteriza-se principalmente como abrigo e para algumas espécies também como alimentação.
