%X The composition of the mesozooplanktonic community was studied in the Punta Morales estuary, Gulf of Nicoya,Pacific coast of Costa Rica,during 1997.Oblique plankton hauls were performed during high and low tide using a 280 ¦Ìm mesh screen net equipped with a flowmeter.The community was characterized by holoplanktonic and meroplanktonic organisms.For the holoplanktonic community,the main groups were copepods (80%)and chaetognaths (16%).The most abundant species were the copepods Acartia lilljeborgii and Paracalanus parvus.A.lilljeborgii is a typical estuarine species that maintains high populations in estuarine systems.Meroplankton was represented mainly by crustacean larvae (66%),and icthyoplankton (18%).The dominance of crustacean larvae and icthyoplankton is an evidence of the ecological importance of the Punta Morales zone.Rev.Biol.Trop.52(4):897-902.Epub 2005 Jun 24. Se estudi¨® la composici¨®n de la comunidad mezoplanct¨®nica en Punta Morales,Golfo de Nicoya, Pac¨ªfico de Costa Rica,en 1997,arrastrando oblicuamente una red de plancton (280 ¦Ìm,con fluj¨®metro)durante marea alta y baja.La comunidad estuvo caracterizada por la presencia de organismos holo y meroplanct¨®nicos.Los principales grupos holoplanct¨®nicos fueron cop¨¦podos (80%)y quetognatos (16%).Las especies m¨¢s abundantes fueron los cop¨¦podos Acartia lilljeborgii y Paracalanus parvus;A. lilljeborgii es una especie estuarina t¨ªpica que mantiene altas poblaciones en sistemas estuarinos.El meroplancton estuvo representado principalmente por larvas de crust¨¢ceos (66%),e ictioplancton (18%).La dominancia de larvas de crust¨¢ceos e ictioplancton evidencian la importancia ecol¨®gica de la zona de Punta Morales.
