Biomass and abundance of Copepoda (Crustacea) in surface waters of the Colombian Pacific Ocean during September, 2007

Twenty-three mesozooplankton samples were taken by oblique tows through the 160 m with a bongo net during September 2007 in the Colombian Pacific Ocean (OPC). The spatio-temporal variation and oceanographic conditions effects on the abundance and volumetric biomass variation of 5 size classes of copepods we re evaluated. Temperature, salinity, dissolved oxygen and chlorophyll-a , per station, and their possible relation to the biomass and abundance of those organisms were analyzed.Original Abstract: Se recolectaron 23 muestras de zooplancton mediante arrastres oblicuos hasta ~160 m con una red bongo durante septiembre de 2007 en el oceano Pacifico colombiano (OPC). Se evaluo el efecto nictimeral y las condiciones oceanograficas sobre las variaciones espaciales y temporales de la abundancia y biomasa volumetrica de 5 clases de tamano de copepodos. Tambien se analizo la temperatura, la salinidad, el oxigeno disuelto y la clorofila-a, por estacion, y su posible relacion con la biomasa y la abundancia de estos organismos.
