本實驗旨在調查1~5年齡九孔的免疫力，分析之免疫指標包括總血球數、血中總蛋白質量、酸性磷酸酶、鹼性磷酸酶、酚氧化酶及超氧歧化酶活性。實驗結果顯示，九孔的2年齡貝雖然在總血球數略低，但在4種與貝類免疫有關的酵素活性都是最高的；而5年齡貝的免疫力顯然是最低的，它在總血球數、血中總蛋白質量、酸性磷酸酶、鹼性磷酸酶、酚氧化酶活性等都居於末位。由於九孔有較高的免疫防疫力方能抵抗人工繁殖時所遇到的緊迫與病原感染，此外，免疫力較強的種貝通常可以產下更健康的後代，因此以2年齡貝作為種貝可能是較適當的選擇。

摘要abstract(英) The work examined the immune activities among 5 age groups of small abalone (Haliotis diversicolor), i.e., 1 year old to 5 years old. The analyzed immune parameters in this study included total hemocyte count (THC), protein content in plasma, and humoral enzyme activities of acid phosphatase (ACP), alakaline phosphatase (ALP), phenoloxidae (PO), superoxide dimutase (SOD). The results showed that 2 years old abalone had the highest enzyme activities in ACP, ALP, PO and SOD but with lower THC. The 5 years old abalone had the lowest THC, protein content, and enzyme activities of ACP, ALP, and PO. We proposed that the abalone with higher immune activities may resist the stress and pathogen infection more effectively during artificial breeding. In addition, there was a positive relationship between parental immunity and offspring health. Thus, the study suggested that the 2 years old abalone could be a better broodstock among the 5 age groups of abalone.
