The cyanophyta are a diverse group prokaryotic photosynthetic microorganisms, distributed in different terrestrial and aquatic environments. Some species of cyanophyta, can form toxic or harmful algal bloom. The objective of this study was to identify the species composition of cyanophyta in fluvio-lagoon systems Pom-Atasta (PA) and East Palisade (PE). Water samples were collected in ten sampling sites in each lagoon, with a van Dorn bottle at the surface and in the middle of the water column, in February, 2011. Twenty one were identified, of which seven species are bloom-forming as: Pseudanabaena catenata, P. limnetica, Anabaenopsis circularis, A. elenkinii, Aphanizomenon cf. ovalisporum, Ap. schindleri and Dolichospermum circinalis. Also, two new records reported: Aphanizomenon cf. ovalisporum y A. schindleri.
