We investigated the effects of a highly saline solution (HS) containing hypochlorous acid, calcium chloride (CaCl 2 ), and phosphoric acid (H 3 PO 4 ) on cell death and growth rate of laver Porphyra yezoensis and green laver Ulva intestinalis. Cell death rates of laver treated with HS and HS plus hypochlorous acid (HS + HOCl) in the harvesting stage were less than 0.5%, and there were no significant differences between the HS and HS + HOCl treatments. However, cell death of green laver treated with HS + HOCl in the harvesting stage was greater than 81.2%. These results indicate that the addition of HOCl is highly effective to eradicate noxious green laver without causing damage to laver. The addition of HOCl and H 3 PO 4 to HS did not increase the area or weight of laver blades. A combination treatment of CaCl 2 and HS, however, significantly increased the area and weight of laver lades compared to controls (P<0.05).
