Table 3. Gambierdiscus species growth parameters at salinities of 10–60.

Individual growth rate measurements were fitted to polynomial curves. The polynomial equations were used for growth parameter estimation: μ_m, maximum growth rate; S_m, salinity of maximum growth; S_opt, salinity of optimum growth range (μ≥0.8×μ_m); S_o, the lower salinity limit for growth; S_u, the upper salinity limit for growth.
