“…Furthermore, the small size of the individuals increases their agility in shallow coastal water connectivity between the fish assemblage. This connectivity between beaches and estuarine environments has been described for subtropical environments (Monteiro-Neto et al, 2008) for species of Clupeiformes, and also in a study by Xavier et al (2012) that observed connectivity between reef systems and mangroves within the same study area.…”

A comparative study involving three mesotidal beaches from reflective to estuarine states was conducted between October 2010 and September 2011 in the estuary of Mamanguape River, northeastern Brazil. The aim was to test for differences in fish assemblages along a morphodynamic continuum, particularly the effects of wave action. In total, 3,732 fish from 71 species were examined; Rhinosardinia bahiensis and Atherinella brasiliensis dominated the estuarine beach, whereas Trachinotus carolinus dominated the reflective beach. Fish assemblages were structured by spatial differences among the sites, and overall abundance, richness and biomass demonstrated a clear increasing trend from the reflective to the estuarine beaches, indicating a primary influence of wave exposure in the measured parameters. The Mamanguape River estuary plays a crucial ecological role as a nursery for several species that depend on its resources and have adapted to the high variability of its physical and chemical factors and the diversity of its habitats.Um estudo comparativo envolvendo três praias mesotidais do estado refletivo para o estuarino foi realizado entre outubro de 2010 e setembro de 2011 no estuário do rio Mamanguape, Nordeste do Brasil. O objetivo foi testar as diferenças nas assembleias de peixes ao longo de um continuum morfodinâmico, particularmente os efeitos da ação das ondas. No total, 3.732 peixes de 71 espécies foram examinados; Rhinosardinia bahiensis e Atherinella brasiliensis dominaram a praia estuarina, enquanto Trachinotus carolinus dominou a praia refletiva. As assembleias de peixes foram estruturadas por diferenças espaciais entre locais de amostragem, e a abundância total, riqueza e biomassa demonstraram uma clara tendência crescente da praia refletiva à praia estuarina, indicando uma influência primária de exposição às ondas nos parâmetros medidos. O estuário do rio Mamanguape desempenha um papel ecológico importante como um berçário para várias espécies que dependem de seus recursos e se adaptaram à alta variabilidade de seus fatores físico-químicos e da diversidade de seus habitats.

“…Coastal zones are areas of ecological transition sites that enable a connection between terrestrial and marine ecosystems, through genetic and biomass exchanges, characterizing them as dynamic and biologically diverse environments (Robertson & Lenanton 1984, Monteiro-Neto et al 2008. Sandy beaches can occur in any type of coast subject to the availability and sufficient volume of sediments to be deposited by the waves above the sea level (Veloso & Neves 2009).…”

Abstract:Resident fishes and their seasonal use of a surf zone were characterized and identified in the Jaguaribe beach, located on the Island of Itamaracá, state of Pernambuco, northeastern Brazil. Monthly towings (March 2006 to February 2007 with a beach seine net (20 m long, 1.5 m high, 5 mm mesh size) in different moon phases and periods of the day (day and night) were conducted. A total of 6,407 specimens, 35 families and 90 species were recorded. Seven species were considered as annual residents (Anchoa tricolor, Anchoviella lepidentostole, Bairdiella ronchus, Larimus breviceps, Lycengraulis grossidens, Polydactylus virginicus and Pomadasys corvinaeformis), three resident throughout the dry season (Conodon nobilis, Lile piquitinga and Menticirrhus americanus) and two resident species in the rainy period (Cathorops spixii and Nicholsina usta). Among these 12 species, concerning their life cycle, three of them (A. tricolor, C. spixii and L. piquitinga ) showed only adult individuals, while B. ronchus, M. americanus and N. usta were the only species represented exclusively by juvenile in both seasons. The surf zone of Jaguaribe beach presents a considerable ecological importance as it encompasses a great diversity of fishes, including species considered rare for this ecosystem, as well as species which are resident annually or seasonally. The distribution pattern of species found in this study shows that the ichthyofauna of the surf zone in Jaguaribe beach is rich, mainly dominated by small-sized individuals including juveniles of several species, with the presence of some species most commonly found in neighboring environments, such as seagrass beds, estuaries and reefs. As an integrated component of interconnected environments in coastal areas of Pernambuco, and owing to its function in the life cycle of coastal fishes, the surf zone of Jaguartibe beach presents an apparently common ecological pattern for tropical sandy beaches. . americanus e N. usta foram as únicas representadas exclusivamente por jovens nas duas estações. A zona de arrebentação da Praia de Jaguaribe possui considerável importância ecológica, uma vez que engloba uma grande diversidade de peixes, incluindo espécies consideradas raras para este ecossistema, bem como espécies que são residentes anual ou sazonalmente. O padrão de distribuição das espécies registradas neste estudo demonstra que a ictiofauna da zona de arrebentação da praia de Jaguaribe é rica, dominada principalmente por indivíduos de pequeno tamanho, incluindo a fase juvenil de várias espécies, com a presença de algumas encontradas comumente em ambientes adjacentes, como banco de fanerógamas, estuários e recifes. Como um componente de ambientes interconectados em áreas costeiras de Pernambuco e por sua função no ciclo de vida de peixes costeiros, a zona de arrebentação da praia de Jaguaribe apresenta um padrão ecológico aparentemente comum em praias arenosas tropicais. Palavras-chave: ictiofauna, Itamaracá, praias arenosas, peixes juvenis.

“…Micropogonias furnieri) are distributed across sandy bottom fishing spots, or that such spots are more readily accessible to fishers most of the time. For instance, the artisanal fishery at Itaipu (CPZ8) concentrates its gill net fishing effort over similar sandy bottom habitats, capturing mostly M. furnieri (Tubino et al, 2007;Monteiro-Neto et al, 2008).…”

“…A similar matrix of species vs fishing gear type was subjected to the same analysis to identify species groups co-occurring in one or more fishing gears. Both dendrograms were generated in the free software Paleontological Statistics (PAST) version 2.17 (Hammer et al, 2001).Nodal analysis using the concepts of ecological constancy (the frequency of occurrence of a group of species in a given fishing spot group) and fidelity (how much a group of species is restricted to a certain fishing spot group, when comparing the individual group constancy to the average constancy of all groups) (Boesch, 1977;Monteiro-Neto et al, 2008), was used to express the relationship between species and fishing spot groups. The following arbitrary scale was established, based on Boesch (1977), considering the range of constancy and fidelity values observed: Constancy -high > 0.7; moderate between 0.5-0.7; low < 0.5; Fidelity -high > 2.0; moderate between 1.0-2.0; low < 1.0.…”

This study characterizes the gill net fishery at Colônia de Pescadores Z13 (CPZ13), in Copacabana, Rio de Janeiro, and its relationship with the marine protected area 'Monumento Natural do Arquipélago das Ilhas Cagarras -MoNa Cagarras', describing the fleet and fishing gears, identifying fishing spots, species and their associations by gillnet type. From June 2012 to May 2013, every Tuesday to Sunday, gill net landings were monitored and fishers interviewed regarding their catch. Small boats (dory whaleboats) are used to set three types of gillnets: "Corvineira" (target species -whitemouth croaker), "linguadeira" (target species -flounders) and "rede-alta" (target species -bluefish). Fifty-nine species within 37 families were captured at 14 fishing spots, showing association with bottom type and distance from shore. The use of fisher's local ecological knowledge defines gear placement at specific sites targeting fisheries resources. All fishing sites are not within the limits of MoNa Cagarras but would benefit from management plans including an MPA buffering zone.Keywords: artisanal fisheries, gillnetting, local knowledge, conservation unit, Cagarras Archipelago. Área marinha protegida e a distribuição espacial da pescaria de rede de emalhe em Copacabana, Rio de Janeiro, RJ, Brasil ResumoEste estudo caracteriza a pesca com rede de emalhe na Colônia de Pescadores Z13 (CPZ13), em Copacabana, Rio de Janeiro, e sua relação com a área marinha protegida "Monumento Natural do Arquipélago das Ilhas Cagarras -MoNa Cagarras", descrevendo a frota e artes de pesca, identificando locais de pesca, as espécies e as suas associações por tipo de rede de emalhe. De junho de 2012 a maio de 2013, de terça a domingo, os desembarques foram monitorados e os pescadores entrevistados em relação à sua captura. As pequenas embarcações são usadas para três tipos de redes de emalhe: "corvineira" (espécie-alvo -corvina), "linguadeira" (espécie-alvo -linguados) e "Rede-Alta" (espécies alvo -anchova). Cinquenta e nove espécies dentro 37 famílias foram capturados em 14 locais de pesca, mostrando associação com o tipo de fundo e distância da costa. O uso do conhecimento ecológico local de pescadores define a colocação dos petrechos em locais específicos destinados ao recursos pesqueiros alvo. Nem todos os locais de pesca estão dentro dos limites da MoNa Cagarras, mas se beneficiariam de planos de gestão, incluindo uma zona de amortecimento para a MPA.Palavras-chave: pesca artesanal, rede de emalhe, conhecimento local, área unidade de conservação, Arquipélago das Cagarras. IntroductionSmall-scale artisanal fisheries play an important role worldwide (FAO, 2012) supporting local and regional markets. Their importance in tropical coastal regions is even more dramatic in the context of food security and health since most of the catch is used for consumption (Batista et al., 2014). They are responsible for 40% of the marine fish taken for human food (FAO, 1998) and comprise about 50 million fishers (Berkes et al., 2001). In Brazil, it account...
