AbstractTo examine optimal growth conditions of the edible green alga Caulerpa okamurae, thalli of this species were cut into erect frond (3cm long) and stolon (5cm long) fragments. They were cultured in combinations of four temperatures (15, 20, 25, and 30 degrees C), three irradiances (20, 40, and 80molphotonsm(-2)s(-1)), four daylengths (8, 12, 16, and 24h), and seven salinities (15, 20, 25, 30, 35, 40, and 45psu). After 12days, maximal relative growth rates (RGRs) for erect fronds (6.78%day(-1)) and stolons (7.02%day(-1)) occurred at 25 degrees C and 40molphotonsm(-2)s(-1). At 30 degrees C, growth differences were found; negative growth for erect fronds and positive growth for stolons, with an average RGR of 1.96%day(-1). A daylength of 16h and salinity of 30psu were needed for maximal growth of erect fronds and stolons. Stolon exhibited a greater tolerance to high and low temperatures and low salinity than erect fronds. Thalli weight of C. okamurae was increased by increments of stolon length, new erect fronds, and new ramuli. In conclusion, C. okamurae should be cultivated in summer with high seawater temperature (25 degrees C) and long daylength, in waters of 30psu, and at a water depth providing 40molphotonsm(-2)s(-1). These physiological and growth pattern data are informative for the successful development of commercial cultivation of C. okamurae.
