Temperature and salinity ranges in which Gymnodinium catenatum (Hiroshima Bay strain) showed specific growth rates higher than 0.2/day were approximately 20-30°C and 20-32. The specific growth rate (μ), expressed as a polynomial equation as functions of temperature (T; °C) and salinity (S) were μ=(-6.84×10-4T2+0.0354T-0.213)×(-1.03×10-3S2+0.0579S-0.548)/0.31; the maximum growth rate (0.31/day) was obtained at 25°C and 30. From a comparison with field data recording temperature, salinity and light intensity, this species may be expected to bloom from summer to autumn in Hiroshima Bay.
