Juveniles and adults of Acanthopagrus arabicus were studied to compare the effect of different salt concentrations (1.5, 7.5, 15, 30 and 45 psu) at 6, 24, 48 and 96 h on activities of the enzymes creatine kinase (CK) in gills, lactate dehydrogenase (LDH) in plasma and alkaline phosphatase (ALP) in intestine. CK and LDH were found to exhibit superior activity in adults compared to juveniles. All enzymes exhibited heightened activity with the increase in salinity and decreased activity with the passage of time in all salinities. Results showed that three enzymes exhibited excellent performance in adults than in juveniles.
研究了赤点石斑鱼幼鱼和成鱼，以比较不同盐度（1.5、7.5、15、30 和 45 psu）在 6、24、48 和 96 小时对鳃肌酸激酶（CK）、血浆乳酸脱氢酶（LDH）和肠碱性磷酸酶（ALP）活性的影响。结果表明，CK 和 LDH 的活性在成鱼中均高于幼鱼。在所有盐度下，所有酶的活性均随盐度的升高而升高，随时间的延长而降低。结果表明，三种酶在成鱼中的表现均优于幼鱼。
