Note
The effects of salinity on growth and physiological processes of marine algae are of considerable complexity. Most experiinental investigations use seawater diluted with distilled or tap water to achieve various water salinities. As Ogata and Matsui (1965) pointed out: "It may generally be said that the changes in salinity, osmotic pressure, pH and also carbon dioxide supply, particularly in natural seawater, are rather inseparably associated." Consequently, few studies have demonstrated unequivocal, general relationships between salinity and various physiological responses in marine algae.
