Resumen
En el presente trabajo se analizan las relaciones entre la composición y distribución del Ictioplancton durante el crucero oceanográfico julio del 2012. Dichas muestras se obtuvieron por medio de arrastres oblícuos, en donde se registraron 15 órdenes, 68 géneros, y 82 especie.
Las mayores densidades se encontraron en las estaciones 1, 2 y 8, En las cuales presentaron amplia distribución y abundancia de larvas, resaltando las especies Argentinidae, Paralepididae, Photichthyidae, Stomiidae, Synodontidae y Myctophidae. La diversidad de especie y abundancia aparecen como parámetros opuestos, la mayor diversidad se dio en la estación 3 mientras que en el resto de estaciones tuvieron un rango similar con promedio de 1 bits.org-1. Las comunidades ictioplanctónicaspresentan asociaciones dando lugar a tres grupos muy bien marcados, que son reguladas por los cambios físicos y químicos del mar.
In this paper the relationship between the composition and distribution of ichthyoplankton larvae level during the oblique tows are analyzed. It was recorded during the sampling, 15 orders, 44 families, 68 genera and 82 species of fish larvae. The highest densities were found at stations 1, 2 and 8 of whom had wide distribution and abundance of herring smelt, Paralepididae, Photichthyidae, Stomiidae, Synodontidae and Myctophidae species. The diversity and abundance of species listed as conflicting parameters, the greatest diversity occurred at station 3 while the other stations had a similar range with an average of 1 bits.org.1. Dendograms change reflected temporary space on the given larval fish communities in neritic / oceanic ecosystems indicating associations are regulated by the physical and chemical changes of the sea.
