Abstract

The present work was carried out in two localities of the Province of Guayas between October and February 2014. The objective of this research was to compare the composition, abundance and distribution of diatoms in the estuarine waters of the Posorja parish and in the General Villamil Canton 71 species were identified taxonomically in which the Central Diatoms predominate with 60 species and 11 species of Diatoms Pennales were recorded. The species with the highest population density was represented by Melosira sulcata in the Posorja sector with 32417 cells. 100m-3, corresponding to 29.86%. While in the sector of General Villamil Playas the species Chaetoceros coarctatus of 15576 cel.100m-3, corresponding to 12.80%. In the two sampled areas out of a total of 36 samples collected. The surface trawls were carried out every two weeks on board a boat, with a 75 HP engine at a speed of 2 knots, in a time of 5 minutes of travel for each station, 1 mile from the seashore. The Shannon - Wiener index shows a similarity between stations. In Posorja there was irregularity in all stations, coinciding with the Simpson index that recorded that there is no similarity between stations.

The abundance and distribution corresponds to 51% of the Diatoms of the order Centrals in Posorja, while 49% concerns General Villamil.
