Abstract
espanolEl objetivo del estudio fue determinar la concentracion celular y la biomasa seca en tres species de microalgas marinas: Chlorella vulgaris, Nannochloropsis oculata y Tetraselmis striata. Las cepas se suministraron por el Laboratorio Costero de Ilo perteneciente al Instituto del Mar del Peru (IMARPE) y luego, se acondicionaron las microalgas para ser cultivadas en medio semicontrolado. Las fases del cultivo de microalgas consistieron en el cepario, inicial, intermedia y masiva. El orden de maxima concentracion celular (cel/mL) para las microalgas fue: Nannochloropsis oculata > Chlorella vulgaris > Tetraselmis striata donde N. oculata represento 7,63 veces superior a T. striata. En el caso de la biomasa, el orden correspondio a: C. vulgaris > T. striata > N. oculata existiendo 1,32 g de diferencia. Se concluyo que, la especie de microalga Chlorella vulgaris indico la mayor ventaja para usarse en la acuicultura comparativamente con las otras dos especies.

The strains were supplied by the Ilo Coastal Laboratory belonging to the Peruvian Institute of the Sea (IMARPE) and then, the microalgae were conditioned to be cultivated in a semi-controlled medium. The phases of the microalgae culture consisted of the cepario, initial, intermediate and massive. The order of maximum cellular concentration (cel/mL) for the microalgae was Nannochloropsis oculata > Chlorella vulgaris > Tetraselmis striata where N. oculata represented 7.63 times higher than T. striata.
