En este estudio se examina la abundancia estructura poblacional y variación temporal del plancton, especialmente de copépodos en el Golfo de Guayaquil, a través de tres años de estudio, en condición no El Niño......Changes on some oceanographic conditions as well surface planktonic community structure were studied during 33 months (December 1999- August 2002) at a fixed station in the Gulf of Guayaquil. Copepods, ostacods and decapod larvae were the most abundant zooplankton (300 µ mesh size) taxa, followed by fish larvae, chaetognaths, medusae, and mysidaceans. The lower abundance taxa were fish eggs, polychaeths, amphipods, pteropods, lamellibranch, cirriped larvae, and gasteropods. Phytoplankton was dominated by diatoms. The effect of the oceanographic variability on the zooplanktonic distribution, abundance, and population dynamics is unknown due to lack of appropriate continuity on sampling and analyses. The two most abundant copepod species were identified. Acartia danae dominated on the dry season, and Labidocera lubbocckii on the rainy season. Although, in general, copepod abundance was high, this diminished during the rainy seasons of 2000 (138-199 org/m3) and 2002 (175-327 org./m3), wit.....
