Resumo: This work was developed in the estuary of the Vaza-Barris River, Sergipe, Brazil, and established nine sampling stations in the hope to ensure maximum representation of the study area. In order to characterize the environment and community ichthyoplankton, we tried to recognize trends and distribution of these organisms to evaluate the role of the estuary as an environment conducive to growth in the early stages of local ichthyofauna. The campaigns were carried out every three months, from April 2010 to January 2011, on two consecutive days during the tide quadrature. For sampling it was used network-cylindrical conical type (500 μm), operated in the flow of ebb tide day and night, with two types of hauls in the surface and one meter deep. The parameters water temperature, dissolved oxygen, salinity, inorganic phosphate, chlorophyll "a", phaeophytin, nitrate and turbidity were obtained in surface of all sampling stations. We collected 38,781 eggs and 3,526 fish larvae. Eggs and larvae were present in all months and all sampling stations. We identified 42 different taxa, distributed in 21 families. The distribution and composition of ichthyoplankton in the estuary of the Vaza-Barris River were strongly influenced by environmental conditions, mainly by the penetration of marine waters through the tidal currents. Some families, like Engraulidae, Gobiidae (Bathygobius soporator, Ctenogobius spp., Gobionellus oceanicus, Gobiosoma nudum and Microgobius meeki), Sciaenidae (Bairdiella ronchus, Cynoscion leiarchus, Macrodon ancylodon, Micropogonias furnieri, Stellifer rastrifer and S. stellifer) and Achiridae (Achirus sp. and Trinectes sp.), occurred throughout the period studied in higher densities, while other rare, as Ostraciidae (Acanthostracion sp.) and Microdesmidae (Microdesmus longipinnis), were recorded for the first time in the region. The fact that families, which are economically and ecologically important, use the estuary during the development of its life cycle, emphasizes the importance of the area in the maintenance of estuarine fish species and the adjacent coastal zone.

Com o objetivo de caracterizar o ambiente e a comunidade ictioplanctônica, procurou-se reconhecer as tendências de distribuição desses organismos e avaliar o papel do estuário como ambiente propício ao desenvolvimento das fases iniciais da ictiofauna local. As campanhas foram realizadas a cada três meses, de abril de 2010 a janeiro de 2011, em dois dias consecutivos durante a maré de quadratura. Para a amostragem foi utilizada rede do tipo cônico-cilíndrica (500 μm), operada nos períodos vazante-diurno e vazante-noturno, em arrastos na superfície e a um metro de profundidade. Os parâmetros temperatura da água, oxigênio dissolvido, salinidade, fosfato inorgânico, clorofila “a”, feofitina, nitrato e turbidez foram obtidos na superfície de todas as estações de amostragem. Foram coletados 38.781 ovos e 3.526 larvas de peixes. Os ovos e as larvas estiveram presentes em todos os meses de amostragem e em todas as estações de coleta . Foram identificados 42 taxa distintos, distribuídos em 21 famílias. A distribuição e composição do ictioplâncton do estuário do rio Vaza-Barris foram fortemente influenciadas pelas condições ambientais, principalmente pela penetração de águas marinhas através das correntes de maré. Algumas famílias, como Engraulidae, Gobiidae (Bathygobius soporator, Ctenogobius spp., Gobionellus oceanicus, Gobiosoma nudum e Microgobius meeki), Sciaenidae (Bairdiella ronchus, Cynoscion leiarchus, Macrodon ancylodon, Micropogonias furnieri, Stellifer rastrifer e S. stellifer) e Achiridae (Achirus sp. e Trinectes sp.), ocorreram durante todo o período estudado em maiores densidades, enquanto outras raras, como Ostraciidae (Acanthostracion sp.) e Microdesmidae (Microdesmus longipinnis), foram registradas pela primeira vez na região. O fato de famílias econômica e ecologicamente importantes utilizarem o estuário durante o desenvolvimento do seu ciclo de vida, enfatiza a importância da área na manutenção da ictiofauna estuarina e da zona costeira adjacente.Submitted by (edna.saturno@ufrpe.br) on 2017-02-17T16:17:53Z No. of bitstreams: 1 Regis Vinicius Souza Santos.pdf: 929113 bytes, checksum: beba8735782c77bc69b5b5649c207373 (MD5)Made available in DSpace on 2017-02-17T16:17:53Z (GMT).
