“…Abundance and richness of fish larvae were also higher in warm months in Ibiraquera lagoon, which is comparable with the channel area of laguna dos Patos (Muelbert & Weiss, 1991), Guanabara Bay (Tovar-Faro & Bonecker, 2000;Castro et al, 2005), the Magdalena-Almejas Bay lagoon system (Avendaño-Ibarra et al, 2004) and Lima estuary (Ramos et al, 2006). In those estuaries, temperature increases are a controlling factor for spawning and recruitment periods (Phonlor, 1984), determining temporal patterns of ichthyoplankton composition, distribution and abundance.…”

This study investigated the variation in abundance, distribution and composition of ichthyoplankton in a lagoon in southern Brazil through the year and at different stations within the lagoon. Ibiraquera Lagoon is a shallow coastal lagoon connected to the sea by a semi-permanent sandbar. Ichthyoplankton samples were collected monthly from December 2003 to December 2004, with a 200 µm mesh net using horizontal surface hauls. A colder, drier period was detected, contrasting with warm months during which salinity varied depending on rainfall and whether the sandbar was open or closed. The mean abundance of ichthyoplankton over the study period was 459.6 ± 76.2 (SE) eggs · 100 m -3 and 63.6 ± 7.9 (SE) larvae · 100 m -3 , and they were present during all months. Significantly higher abundances of eggs and larvae were observed during warm months. The community was dominated by the family Engraulidae followed by Clupeidae, Gobiidae and Mugilidae. Engraulidae and Clupeidae were present throughout the year, with greater abundances in months with higher temperatures. Some coastal fish species spawn in Ibiraquera Lagoon, mainly near to the sandbar, demonstrating that the lagoon is a spawning area for coastal stock. We recommend the establishment of environmental procedures to promote the conservation of Ibiraquera Lagoon and its ichthyoplankton community.A abundância, distribuição e composição do ictioplâncton foram investigadas em uma lagoa no sul do Brasil durante um ano e em diferentes estações dentro da lagoa. A lagoa de Ibiraquera é uma lagoa costeira rasa, conectada ao mar através de uma barra semi-permanente. As amostras de ictioplâncton foram coletadas mensalmente entre dezembro de 2003 e dezembro de 2004, com uma rede cônico-cilíndrica de 200 µm de malha em arrastos horizontais e de superfície. Foi detectado um período frio e seco em contraste aos meses quentes e com variação na salinidade em função das chuvas e da barra estar aberta ou fechada. A abundância média do ictioplâncton, durante o período de estudo, foi de 459,6 ± 76,2 (SE) ovos · 100 m -3 e 63,6 ± 7,9 (SE) larvas · 100 m -3 , e ocorreram em todos os meses. As abundâncias de ovos e larvas foram significativamente maiores nos meses quentes. A comunidade foi dominada pela família Engraulidae seguida pelas famílias Clupeidae, Gobiidae e Mugilidae. As famílias Engraulidae e Clupeidae ocorreram principalmente nos meses com maiores temperaturas. Alguns peixes costeiros desovam dentro da lagoa, principalmente próximo a barra, evidenciando que a lagoa é uma área de desova para o estoque costeiro. Recomenda-se o estabelecimento de ações ambientais que promovam a conservação da lagoa de Ibiraquera e da comunidade ictioplanctônica.

“…The importance of shallow coastal biotopes in the maintenance of fish assemblages has been clearly demonstrated by studies conducted worldwide (Layman, 2000;Ramos et al, 2006;Kruger & Strydom, 2010;Woodland et al, 2012). These biotopes are often described as nursery habitats or recruitment areas for fish because they provide a great abundance of food resources and protection from predation.…”

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.

An extensive literature base worldwide demonstrates how spatial differences in estuarine fish assemblages are related to those in the environment at (bio)regional, estuary-wide or local (withinestuary) scales. Few studies, however, have examined all three scales, and those including more than one have often focused at the level of individual environmental variables rather than scales as a whole. This study has identified those spatial scales of environmental differences, across regional, estuary-wide and local levels, that are most important in structuring ichthyofaunal composition throughout south-western Australian estuaries. It is the first to adopt this approach for temperate microtidal waters. To achieve this, we have employed a novel approach to the BIOENV routine in PRIMER v6 and a modified global BEST test in an alpha version of PRIMER v7. A combination of all three scales best matched the pattern of ichthyofaunal differences across the study area (ρ = 0.59; P = 0.001), with estuary-wide and regional scales accounting for about twice the variability of local scales. A shade plot analysis showed these broader-scale ichthyofaunal differences were driven by a greater diversity of marine and estuarine species in the permanently-open west coast estuaries and higher numbers of several small estuarine species in the periodically-open south coast estuaries. When interaction effects were explored, strong but contrasting influences of local environmental scales were revealed within each region and estuary type. A quantitative decision tree for predicting the fish fauna at any nearshore estuarine site in south-western Australia has also been produced. The estuarine management implications of the above findings are highlighted.
