Abstract

Land-based cultivation of a green alga, Ulva prolifera, was tried by using the pumped saline groundwater at Miho Peninsula in Shizuoka, Japan, from August to December 2003. Fronds of 1 to 6-week-old were cultured in 6 outdoor tanks (500l or 1, 000l in volume) for a week at a turnover rate of three times a day under the sunlight. Initial frond density was 0.1g/l. The daily growth rates of 1- to 6-week-old fronds were 35.8, 47.4, 44.5, 24.8, 18.5 and 4.9%, respectively. Although maturation caused relatively low growth rates of a part of 4-and all 5-and 6-week-old fronds, but those of 2-and 3-week-old fronds were 45.8%, higher than previous records. Saline groundwater had constant and suitable water temperature (19.9±0.2°C), salinity (33.65±0.08 PSU) and pH (7.36±0.12) with suitable inorganic nitrogen (332.0±64.5 p mol/l) and phosphate (0.71±0.13μmol/l) . These revealed that saline groundwater is strongly recommended for the green algal culture.
