Resumen
El presente estudio es el resultado del analisis de muestras fitoplanctonicas de 22 estaciones colectadas en el crucero oceanografico TO1/02/01 O a bordo de Tohalli, del Instituto Nacional de Pesca(INP) durante febrero. Correspondiendo a estaciones costeras y oceanicas en aguas ecuatorianas, para la cual se colectaron mediante arrastres verticales de 50m de profundidad a a la superficie, empleando una red cónica simple, con poro de malla de 55u. ubicadas geograficamente hasta los 82º W de longitud, y a 1º N hasta 3º S de lalitud. En el mes de febrero de 2001, se presentaron temperaturas ligeramente calidas propias para la epoca, las masas de aguas calidas desplazaron a la corriente de Humboldt hacia el sur con temperaturas que entre los 24º C y 28º C. Entre la epoca fria y epoca calida en la region costera ecuatoriana. La composicion, distribucion y abundacia de las poblaciones de dinoflagelados, estuvieron asociadas a las condiciones oceanograficas de " LA NIÑA ", pudiendo identificar un total de 63 especies. dentro de los dinoflagelados mas abundantes se identificaron especies reportadas para aguas templadas- calidas, a tropicales como:dinnophysis caudata, cerantium tripos subsp. semipulchellum, cerantium tripos forma tripodiodes, cerantium azoricum, cerntium deflexum, cerantium porrectum, cerantium arietunum. Goniodoma polyedricum.- especie cosmopolita de aguas subtropicales a tropicales, cerantium furca y cerantium longipes, cosmopolita de aguas templadas-frias a tropicales, y la especie protoperidinium divergens, cosmopolita de aguas templadas a tropicales. Alguna especies de dinoflagelados originaron "bloom" como: cer<ntium tripos subsp.semipulchellum 10.00 cél/m3, dinophysis caudata 13.000 cél/m3, pyrophacus steinii 11.00 cél/m3.
The presente research is the result of analysis phytoplankton sample of 22 stations, collected on the cruise oceanographic T01/0201 Ocarried out by the 2tphalli", of the National Fisheries Institute (NFI), during february 2001. corresponding to costal ans¡d oceanic stations in ecuadorian waters, for which were carried out by means of vertical 50 m depth to the surfae, use simple conical net with pore of mesh of 55 u. the tows were geographically locatednat 82º W longitude, and 1º N to 3º S latitude. In february 2001, there slighthy warn temperatures proper for that season; the warmer mass of water displays the cold Humboldt Current to the south with temperatures within 24ºC to 28º . Between the cold and warm season at the ecuadorian coastal region. The composition, distribution and abundance of dinoflagellates poulations were associated with the oceanographic conditions of LA NIÑA, and a total of 63 species were identified. Dinophysis caudata, cerantium tripos subsp. semipulchellum, cerantium tripos forma tripodiodes, cerantium vultur, cerantium deflexum, cerantium porrectum, cerantium arietumum, Goniodoma polyedricum.- Cosmopolitan in tropical to subtropical waters; cerantium furca and cerantium longipes, cosmopolitan in cold temperate to tropical waters, anda tghe protoperidium divergens, cosmopolitan temperate to tropical waters. Some species of dinoflagellates originated "bloom" as: cerantium tripos subsp. semipulchellum 10.00 cél/m3, dinophysis caudata 13.000 cél/m3, pyrophacus steinii 11.000 cél/m3.
