Effects of salinity and nutrient conditions on growth and haemolytic activity of Fibrocapsa japonica (Raphidophyceae)

The influence of salinity and a number of nitrogen (N) and phosphorus (P) levels on growth and haemolytic activity of the harmful algal bloom (HAB) species Fibrocapsa japonica were studied simultaneously. The F japonica strain studied had a euryhaline growth profile with an optimum growth rate at 26 psu. Measurements of the minimum cell quota of N and P revealed an optimum N:P ratio of 24.5 and a relatively high requirement of nutrients (q(0)N = 7.1 pmol cell(-1); q(0)P = 0.29 pmol cell(-1)). These characteristics fit the habitat of this species, among which is the P-controlled eutrophied Dutc... Mehr ...
