En ambientes costeros uno de los principales problemas de contaminacin ocasionados por la actividad antrpica est relacionado con el aumento excesivo de nutrientes que son transportados a travs de los ros y de las descargas urbanas.En sus ms serias manifestaciones lleva a florecimientos algales visibles, espumas de algas, excesivo crecimiento de algas bentnicas y crecimiento masivo de macrfitas sumergidas y flotantes. Es un hecho demostrado que episodios de floraciones algales y fenmenos de toxicidad que afectan a la biota marina y al hombre, se presentan habitualmente en zonas costeras eutroficadas. Los objetivos de este estudio fueron analizar la estructura y dinmica del fitoplancton, con especial nfasis en las especies nocivas en un ambiente costero de la provincia del Chubut: baha Nueva, sometida a perturbacin antrpica y las condiciones ambientales especficas en las que se desarroll la comunidad bajo estudio. Se realizaron experiencias de laboratorio para analizar el efecto del enriquecimiento de nutrientes con especies fitoplanctnicas aisladas del ambiente costero.Se detectectaron floraciones algales de especies nocivas productoras de biotoxinas.
