“…Itacolomis presents a high diversity of fauna, with many species of reef fish (Daros 2010 ; Santos et al 2018 ). It is the furthest islet off the Paraná coast, located approximately eight nmi from Municipality of Matinhos, 7.3 nmi from the Guaratuba Bay mouth and 7 nmi from Currais Island (Lorenzi and Borzone 2009 ; Daros 2010 ; Santos et al 2018 ). In addition to artisanal fishing carried out around the island, recreational fishing (i.e., spearfishing and angling targeting sook fish and tunas) is also performed.…”

Current status and potential contributions of fisheries statistics from artisanal fisheries for managing juvenile istiophorid billfishes in Southern Brazil

Billfishes are considered important fishery resources and the identification of aggregation sites is imperative for proper management. Here we present evidence of a seasonal aggregation site for juvenile istiophorid billfishes in southern Brazil. We discuss the results as they relate with the need for management at a local scale and participatory monitoring with artisanal fishing communities as a way to ensure access to data on the occurrence and population status in the long term.

“…Previous studies of the marine environment tended to focus on the ichthyofauna (Félix & Harckradt 2008, Harckradt & Félix-Harckradt 2009, Daros et al 2012. Only one study examined the soft bottom infauna (Lorenzi & Borzone 2009), three examined benthic invertebrates on hard substrates, one of ascidians (Rocha & Faria 2005) and two experimental studies on temporal colonization of artificial substrates near the islands (Brandini & Silva 2011, Bumbeer & Rocha 2012. Since the creation of the MPA, there has been only one study of marine biota, which examined the algal community (Pellizzari et al 2014).…”

This study describes the biodiversity of benthic invertebrates on hard substrates in the Currais Marine Protected Area (Currais MPA), in the state of Paraná. The benthic community was sampled during 2012 to 2015, in winter and summer, at two islands and four groups of artificial reefs (ARs). Samples were collected along shallow (2-4 m) and deep (6-8 m) transects at the islands and ~18 m transects at the ARs. We also searched the literature to review all published records of benthic invertebrates on hard substrates in the Currais MPA. We recorded 176 taxa in the phyla Annelida (class Polychaeta), Arthropoda (class Maxillopoda, order Sessilia), Bryozoa, Cnidaria, Chordata (class Ascidiacea), Echinodermata, Mollusca and Porifera, in 13 classes, 40 orders and 75 families. With these 102 new records, our list comprises 58% of all recorded species. Of these, 58 taxa were first records for the state of Paraná. This remarkable number of new records highlights that biodiversity studies are lacking in Paraná. Fifteen non-indigenous species and one endangered species, the sea star Coscinasterias tenuispina (Lamarck, 1816), are included. This is an important transitional area to monitor expansion or constriction of the latitudinal distributions of species, in the context of climate change, that may influence the geographical distribution of species (both native and invasive). This study is the first inventory of marine hard substrate habitats of the Currais MPA with a surprisingly diverse community.

“…The physical presence of the reef structure and the water flux generated by waves and currents constantly remobilizes the nearby sediment, mainly in shallow areas (Reineck & Singh, 1973; Fritz & Moore, 1988). These modifications in the wave marks in the reef environment may promote alterations in the composition and abundance of benthic organisms, mainly those that live in the upper layers of the sediment, or at the sediment–water interface (Lorenzi, 2004). However, information on changes in the hydrodynamics induced by cement blocks is scarce (Ambrose & Anderson, 1990; Badalammenti & D'Anna, 1996; Danovaro et al , 2002; Fabi et al , 2002).…”

“…The reefs are not self-sustainable since many predators that are associated with these environments use the reef structures mainly for shelter and depend on the adjacent unconsolidated sediment to obtain food (Parrish & Zimmerman, 1977; Bray et al , 1981; Nelson et al , 1988; Hueckel et al , 1989; Frazer et al , 1991; Posey & Ambrose, 1994). The predation exerted by the ichthyofauna on the unconsolidated substrate community may form a trophic halo, reducing the occurrence of these preys close to the structures (Posey & Ambrose, 1994; Barros et al , 2001; Lorenzi & Borzone, 2009). Ambrose & Anderson (1990) suggest that physical parameters may influence the infauna abundance pattern more than predation, and reef distance was considered the principal factor influencing the community.…”

“…In Brazil, the studies have followed the same tendency in the State of Ceará (Conceição et al , 2007) and in the north of the State of Rio de Janeiro (Zalmon & Gomes, 2003; Krohling et al , 2006; Brotto & Zalmon, 2007; Krohling et al , 2008; Santos et al , 2010). Two exceptions are the studies of Soares-Gomes et al (2000) that characterized the meiofauna around an oil rig off Rio de Janeiro and Lorenzi (2004) that characterized the infauna associated with an artificial reef employed in the south of Brazil.…”

Artificial reef influence on the surrounding infauna—north coast of Rio de Janeiro State, Brazil

There have been many efforts to appraise the extent to which artificial reefs affect the surrounding community, but few studies addressed whether benthic assemblages change with distance from the reef. We experimentally assessed the relationship between infauna abundance and richness with increased distance (0, 5, 25, 50, 100 and 300 m) from reefballs deployed on a flat and homogeneous bottom, 9-m deep, on the north coast of Rio de Janeiro, south-eastern Brazil. Benthic taxon richness and abundance varied significantly between surveys with higher values in February 2007. Both numerical indicators changed similarly with distance, but more noticeably between 300 m and the other distance treatments where abundance was highest. A non-metric multidimensional scaling ordination revealed that macrobenthic assemblages were very heterogeneous with significant differences between surveys but not among sampling distances. A canonical correspondence analysis including species, distances and sediment variables showed that the distances 5, 25 and 100 m were related to organic matter and mud (fine sediment), while 0 and 300 m distances were more related to the non-organic variables, such as the percentage of gravel, sand and calcium carbonate. Spatial variations in the parameters of the sediment alone did not explain the distribution of the associated infauna, given the similarity of the community at different distances. It is suggested that the influence of artificial reefs is quickly dissipated due to strong bottom sea currents, indicating a reduced impact or influence of these reefs on the surrounding infauna.
