This study investigated healing of experimentally wounded carp (length of wound:1cm, depth of wound: 0.5cm) with various concentrations and times of salt bath under laboratory conditions at temperature of 13-18ºC. This was in to improve the healing process in skin lesions. Fifteen treatment groups of fish (body weight 5.2±2.03g) were bathed with various concentrations: 1%, 2% and 3% and various times: 1, 2, 3, 4 and 5 and one group without any bath as control. After wounding, all of the wounded carp were put in salt bath and all treatment were divided to 3 groups. First group put in 1%, Second group put in 2% and group 3 put in 3% concentration of salt bath, any of these in divided to 5 groups and difference of these was in times of salt bath. Wounded tissues were sampled in 3, 7, 10, 14, 17, 21, and 30 days after making the incision. During the 28 day period of wound healing there were statistically significant changes in among treatments with 1%, 2% and 3% concentration of salt. Histological analysis revealed that incision in treatments with 2% and 3% concentration of salt healed better. Therefore, salt bath with 2% and 3% concentration improve wound healing in carp under the conditions of this study.
