Changes in Non-specific Immunity and Activities of Antioxidant Enzymes of Eopalaemon carinicauda in Response to Different Salinities

In order to research the effect of different salinities in immune status of Eopalaemon carinicauda, the non-specific immune function and activities of antioxidant enzymes were studies in five salinities(11.0, 16.2, 21.4, 26.6 and 31.8). Five immune related enzymes(ACP, AKP, LSZ, T-AOC and SOD) of muscle and hepatopancreas were detected. The results showed that the activities of the four immune related enzymes(ACP, AKP, T-AOC and SOD) in the hepatopancreas were higher than that in the muscle; the activities were significantly different in different salinity group except the activity of LSZ in the muscle. The hepatopancreas ACP, AKP activities of salinity 26.6 were significantly higher than that of the other three salinities(11.0, 16.2 and 21.4)(P0.05); hepatopancreas LSZ activities have shown significantly different in the five salinities group(P 0.05), of which the 26.6 salinity group was the highest; T-AOC, SOD activities were significantly different in hepatopancreas of the five salinities group(P0.05), of which the 31.8 salinity group was the highest, the 21.4 salinity group was the lowest.
