| Abstract: | El objetivo del presente estudio es determinar los cambios poblacionales durante las estaciones cálida y fría de este grupo taxonómico y del zooplancton acompañante más abundante en aguas de la Bahía de Santa Elena vs. las variables ambientales temperatura y salinidad.
The present work is based on the cuali-quantitative zooplankton analysis and frequency of present groups regarding 240 plankton samples collected twice a month in 6 stations in coastal superficial waters during the winter and summer in front of Santa Elena's Bay (La Libertad) between december 2004- november 2005. It were determined 19 zooplankton groups, being the dominant ones: cladocera Penilia avirrostris and Evadne tergentina, copepod, eggs and larvae of fish and brachyura zoeas. Two cladocera species were determined: species Penilia avirrostris and Evadne tergentina; their distribution in dry season is notorious with a numerous population of P. avirrostris, when the temperature of the sea reports ranges from 20 to 22°C. |
