“…As stated by Smith & Tyler (1975) coral domes of considerable internal volume and structural complexity favor a diversified and dense fish community of different species and sizes. Other studies using gill nets in artificial reefs (D`Anna et al, 2004;Gomes et al, 2001;Godoy, Almeida & Zalmon, 2002) related increasing fish diversity and abundance to higher structural complexity of the substrate. In contrast, Fabi & Fiorentini (1994) and Santos & Monteiro (1998) suggest that trammel and gill nets could not identify differences among fish communities of artificial reefs and other substrates.…”

Uma das principais questões em estudos recifes artificiais refere-se aos agentes modeladores da comunidade íctica associada. Módulos de concreto experimentais foram distribuídos na costa norte do estado do Rio de Janeiro (21o 29'S, 41o 00W) de acordo com a combinação da complexidade estrutural através da presença/ausência de cavidades e de superfície favorável/desfavorável à colonização bêntica. O programa de amostragem (março de 2002 a março de 2003) consistiu de capturas mensais com redes de espera de fundo por 24 horas. Os valores de densidade por espécie, densidade por grupo funcional de acordo com a posição na coluna d´água, tipo preferencial de substrato, hábito alimentar, sexo e estágio ontogenético e os descritores de comunidade não revelaram diferenças significativas (ANOVA, p > 0,05) entre as unidades recifais e entre os tipos de módulos. O dispositivo de pesca é seletivo para peixes pelágicos e demersais, sugerindo baixa associação com os módulos recifais. O maior número de presas nos módulos com bentos sugere uma predação íctica sobre a comunidade bêntica mais diversificada. Os peixes fêmea mostraram uma associação com os módulos sem complexidade estrutural. Uma maior similaridade entre os módulos com complexidade foi observada para diversidade, densidade e composição do conteúdo estomacal. A complexidade estrutural desempenhou um papel mais importante como agente modelador da comunidade íctica nos módulos recifais do que a presença de comunidade bêntica, embora esta última implique em recursos alimentares mais diversificados para a ictiofauna associada.

“…The studied area is located in a transition region between the tropical and subtropical fish fauna of the south-east Atlantic (Gomes et al , 2001). As a result of the tropical and subtropical features it is possible to find a relatively rich ichthyofauna in the area, with species from all parts of the Brazilian coast.…”

Wet biomass of principal plankton components and whole plankton standing stock were assessed in waters of the Heron Island ring reef and surrounding deep lagoon. Biomass of phytoplankton ranged between 30 to 120 mg m 23 , without its pronounced depletion over the reef shallows. Picocyanobacteria and prochlorophyte algae contributed over 70% of this biomass. Biomass of bacterioplankton varied between 75 to 340 mg m 23 , with its maximum over the reef flat. Biomass of planktonic protozoa's ciliates and zooflagellates ranged between 20 to 110 mg m 23 . The daytime biomass of zooplankton varied between 490 to 1590 mg m 23 in the deep lagoon in the zone of intense tidal currents. Over the reef shallows, it was 10-20 mg m 23 . At night, it rose there up to 800 to 4000 mg m 23 as the result of emerging demersal zooplankton from the benthic substrates. The time scale of nocturnal emerging by different taxa was also documented. Biomass of whole demersal zooplankton communities hiding by the daytime in bottom substrates at the reef flat was found to be over 100 g m 22 . Problems of nutrition planktivore reef fauna related to the plankton production and abundance are discussed. . (1983) Technique for enumeration of nanoplankton using epifluorescence microscopy.

“…In relation to the finfish distribution, the results of our study compared with those of Gomes et al (2001), revealed a co-occurrence of nine species between their artificial reefs and the Orion reef. In both studies, these species also occurred in control areas except for Caranx latus, which was exclusive of the Orion reef.…”

“…In our study the average distance (~100 m) from the shipwreck promotes a global description of the associated reef fish assemblages catching resident and also transient species, which occurs in the artisanal and commercial fisheries landings. In the northern coast of Rio de Janeiro, Gomes et al (2001) and Santos et al (2010) assessed the fish assemblages' sorting different sets of gillnets at a mean distance of 50 m from the artificial structures. Santos et al (2010) indicated that artificial reefs are a promising management tools to artisanal fisheries in that area, depending on the target species and the fishing distance from the reefs (maximum of 300 m on their study).…”

The effect of the Orion shipwreck on fish assemblage distribution near the reef was studied to the northeast of Rio de Janeiro with six different fishing gears: gillnets, mid-water longlines, circular traps, rectangular traps, vertical longlines, and bottom trawling. The study consisted of a pre-monitoring survey four months before the shipwreck in the area (A) and in two control areas (B and C). After 36 months, a total of 56 species were caught in the Orion reef area, 49 in control area B and 59 in control area C. The similarity analysis, considering the number of fish caught during the nine surveys in the three study areas, clustered the pre-monitoring and first post-settlement surveys of the three sites. This occurred due to the low number of fish captured and the dominance of Trichiurus lepturus and Lagocephalus laevigatus. These results differed from all the other studies in the three areas due to the co-dominance of Ctenosciaena gracilicirrhus and Stephanolepis hispidus. Such spatial similarity shows the low influence of the Orion reef in the area after three years. Biomass values were 15% higher in the Orion reef area than in the control areas, representing an increase of up to 1.2 times in wet weight. The increment of fish communities is still insufficient for proposing sustainable fishery activity in the shipwreck area. The monitoring time (32 months) after the sinking of the Orion may be considered too short to assure that the wreckage had reached its maturity as an artificial reef, either as a fish attractor or producer.
