Salinity adaptation in the ichthyotoxic golden alga


January 2017 - June 2019


Highlights of completed study

• High salinity suppressed growth rate and maximum density of the harmful algal species, Prymnesium parvum
• Incrementally increased salinity did not prevent growth inhibition at high salinity
• Compensation was observed over time for growth rate but not maximum density
• Growth inhibition did not occur in full sea-salt, high-salinity medium
• Results provide new insights on P. parvum’s ability to grow in saline environments
