Effects of salinity on the growth rate, morphology and water content of some Brazilian red algae of economic importance

Abstract

The study comprises three agarophytic (Gracilaria aff. verrucosa, Gracilaria sp., Pterocladia capillacea) and three carrageenophytic algae (Meristiella echinocarpa, Hypnea cornuta, H. musciformis), subjected to salinities from 5-60‰. All species were more tolerant to salinities >30‰ than below this value, with maximum growth occurring between 25-40‰. -from Authors
