Abstract: During the oceanographic cruises (T95/10/04 DO, B/I Tohalli) which were carried out during the period between the 2nd-6nd of november 1995, along the from the coast at 81~'20'W and between 01~'10' to 03~'20'S, 17 differents phytoplankton station, were surveyed for each station vertical drags were done in a water colum of 50 m depth by using of 47,5 cm diameter, 130 cm long and 55~km of light ned. The cualitative and quantitative plankton analysis shown that the studied area correspond to biological fertility region with Rhizosolenia styliformis, Coscinodiscus marginatus an Ceratium tripos as the dominant spacies. An area of phytoplankton activity is identifie as of having an outcrop origine (station 7, 8 and 9). The station that presented the major plankton density was the one numbered 23 (80~'20'W and 03~'05'S) with 4,7 x 105 cel.m-3 likely due to the nutrients that flow into from Guayas river while the minimun concentrations were found to happen at stations 10 and 20 with 9,9 x 103 y 4,2 x 103 cel.m-3 respectively. The zone showed present a total of 37 families and 115 species.
