Prorocentrum lima has presented frequent studies in the aquaculture area, within security control of bivalve mollusks. This dinoflagellate has not been cultivated on a large scale in an autotrophic framework with inorganic culture media. The present study seeks to understand its epiphyte-benthic character and its interactions with some macroalgae to develop new technologies and cultivate it on a large scale. The P. lima strain was isolated from Codium fragile, and in culture with inorganic medium its maximum cell density (20 317 cells mL-1) was obtained on day 24, with an average growth rate of 0.0815 ± 0.2027 div day-1. In a mesocosm culture simulation under natural and controlled environmental conditions, P. lima epiphyted the macroalgae Agarophyton chilensis, Ulva spp. and C. fragile, in addition to all the inert structures present in the culture ponds. However, it presented the highest density (80 053 cells g-1 FW) on A. chilensis, under controlled conditions at 13 days of culture. The macroalgae would be providing specific organic nutrients that would stimulate the growth of P. lima.
