Abstract

Alexandrium tamarense is one of the main toxic red-tide-algae which can produced Paralytic Shellfish Poisoning (PSP) and often burst out to form blooms in globe oceans. The growth characteristics of this unicellular alga was observed by artificial culture in laboratory. In addition we have confirmed the adscription and have detected toxins of this alga. The result demonstrate that the optimum situation is: T=22~26°C; S=28~31 ; L=1500~2500 lux and L/D=16/8h. The growth pattern accord with the Logistic Equation and the average double arise time is 85h.
