determiningoptimalgrowth conditions for thehighest biomassmicroalgae species inlithuanian part of thecuronianlagoon for furthercultivation

anthropogenic eutrophication conditioned frequent and more pronounced blooms of toxicalgae and cyanobacteria in the fresh and saline aquatic ecosystems all world around. however, bloomingspecies could serve as a possible resource instead of a threat by exploiting them to remediate nutrients. theoptimised use of algae and cyanobacteria may provide the environmental service together with economicbenefit that could be obtained from their biomass. the aim of this study was to identify microalgae speciesfrom curonian lagoon that could be prospective candidates for cultivation in lithuania, and statisticallydetermine how the accumulation of their biomass correlated with the changes in environmental conditions,using five years monitoring data. five species, frequently acquiring a much larger biomass (up to 70 mg/l) over other species, were identified: aphanizomenon flos-aquae, planktothrix agardhii, actinocyclusnormanii f. subsalsus, diatoma tenuis and stephanodiscus rotula. the optimal cultivation conditionswere proposed based on results of the analysis and the potential their biomass applications are discussed.
