          Abstract

          Con el fin de contribuir al conocimiento del fitoplancton potencialmente toxígeno de la cuenca pacífica colombiana, se describe su distribución, frecuencia y abundancia en muestras tomadas en once cruceros, entre 2004 y 2011. Estos cruceros fueron realizados en el marco del Estudio Regional del Fenómeno de El Niño en el Pacífico Sudeste (ERFEN), programa multinacional de la Comisión Permanente del Pacífico Sur (CPPS). En los resultados se destacan por su amplia distribución, permanencia y abundancia los géneros Pseudo-nitzschia, Dinophysis, Gonyaulax y Alexandrium, los cuales han sido registrados como causantes de intoxicaciones amnésicas (Pseudo-nitzschia), diarreicas (Dinophysis y Gonyaulax) y paralizantes (Alexandrium). A pesar de que algunos de ellos fueron abundantes en el plancton, durante los muestreos no fueron evidentes cambios en la coloración del agua, ni se tuvo registros de que hubieran causado efectos nocivos durante el periodo de estudio.

          Translated abstract

          In order to contribute to the knowledge of potentially toxigenic phytoplankton, the frequency, distribution and abundance of these organisms in samples from eleven cruises conducted in the Colombian Pacific basin from 2004 to 2011 is described. The research cruises were conducted under the Regional Study of the "El Niño" phenomenon in the Southeast Pacific (ERFEN), a multinational program of the Permanent Commission for the South Pacific (CPPS). Genera Pseudo-nitzschia, Dinophysis, Gonyaulax, and Alexandrium are remarkable in the results because of their wide distribution, persistence and abundance. These species have been reported to cause amnesic intoxications (Pseudonitzschia), diarrhea (Dinophysis and Gonyaulax), and paralytic poisoning (Alexandrium). Although some of these species were abundant in the plankton, there were not obvious changes in water coloration or reports of adverse effects during the study period.
