Relación entre la determinación del pigmento Clorofila a y el Biovolumen geométrico algal en un lago de planicie de inundación (Ciénaga de Ayapel, Córdoba-Colombia)

the estimation of biomass of planktonic algae can be done by two methods, the quantification of geometric biovolume and chlorophyll α. this work which considers as environmental scenario the ayapel-cordoba flood-plain lake, introduces (presents) the two protocols for geometric biovolume and chlorophyll α quantification, and shows that both variables actually represent differences in biomass in space and time, also recording a high degree correlation. the results show that by using an appropriate extraction method for chlorophyll α, it is possible to have a quick and effective method for determining the biomass of algae that can be used to apply a trophic classification, which can also be obtained by counting and estimation microscopic geometric dimensions.
