本研究在建立克氏海葵魚 (Amphiprion clarkii) 之人工繁殖及育苗技術提供產業之應用，以減少野外採捕之壓力。種魚在人工環境下自然產卵，受精卵為橘紅色、長橢圓形、分離之沉性黏著卵，受精卵之平均長徑為 2.53 ± 0.08 mm、平均短徑為 0.94 ± 0.04 mm、平均卵黃長徑為 1.64 ± 0.06 mm、平均油球徑為0.17 ± 0.04 mm，仔魚孵化平均體長為 4.93 ± 0.06 mm。產卵結束後，種魚有護卵行為，胚胎孵化所需的時間與水溫成反比。仔魚孵化後第 7 天左右體色開始出現，並逐漸轉變為橘紅色；成長至第 10 天時，體側可明顯發現二條橫帶，此時可以與海葵共生而不會受到海葵攻擊。仔魚初期餌料生物系列為輪蟲與橈腳類，添加微藻有穩定水質及滋養輪蟲之功效，餌料生物之提供應重疊使用。仔魚成長至 20 日左右開始可以接受人工飼料，至180 日時，仔魚體長可達 49.60 ± 10.18 mm，此時之體色及斑紋已與成魚一致。

This study sought to understand the reproductive behavior and larviculture of Amphiprion clarkii in artificial environments. Moreover, we hope that the results of this study can be used to reduce the trade in wild populations of this species in the ornamental fish market in the future. The results showed that the adhesive demersal eggs of the species are orange in color and ellipsoidal on the surface, with each egg being about 2.53 ± 0.08 mm (Mean ± SD) in total length and 0.94 ± 0.04 mm in width. The yolks were each about 1.64 ± 0.06 mm long and contained several oil droplets with an average diameter of 0.17 ± 0.04 mm, and the newly hatched larvae were about 4.93 ± 0.06 mm in length. In the initial larval stage, the hatchlings were first fed with rotifers. In addition, microalgae were added to stabilize the water quality and to nourish the rotifers. The feedings should be provided consistently at the same time. On the 20th day after hatching, a pellet diet can be provided to the fish fries. On the 180th day, the average body length of the juveniles was 49.60 ± 10.18 mm, and the band pattern and colors of the juveniles were the same as those of adults.
