一、本研究主要目的是建立黃高鰭刺尾鯛人工繁殖養殖技術，並提供相關技術給業者作為其他海水魚繁殖之參考。
二、建立培育高鰭刺尾鯛種魚之技術，以達成自然配對及產卵之目標，並培育種魚超過100尾。
三、建立高鰭刺尾鯛育苗技術，了解種苗繁殖所需之餌料生物系列，仔魚對水質及微細藻類需求，以作為種苗大量培養之參考。
四、本試驗以人類絨毛膜促性腺激素及促黃體激素釋放激素誘導黃高鰭刺尾鯛產卵。注射劑量為1000 IU/尾及LHRH-A50 μg/尾注射後約36小時左右開始產卵黃高鰭刺尾鯛卵呈浮性之透明卵，其卵徑為 0.70 ± 0.06 mm，內含一顆油球，油球直徑為0.17 ± 0.01 mm，水溫介於22.9 - 24.6 ℃及鹽度為32 psu下受精卵於42小時後孵化，孵化仔魚體長為2.17 ± 0.36 mm。

1.Establish artificial propagation techniques for Zebrasoma flavescens, transferring to the fishery as a reference for rear other species.
2.Establish the techniques on rearing parent Zebrasoma flavescens to achieve the goal of natural mating and spawning and rearing parent Zebrasoma flavescens for more than 100 individuals.
3.Establish the techniques for larval rearing of Zebrasoma flavescens and understand the requirement of feedings, water quality and microalgae as a reference for massive larval rearing.
4.This study investigated the efficacy of induced spawning in Yellow tang Zebrasoma flavescens by injection of HCG and LHRH-a. Injected dosages of 1000 IU and 50 μg were, ovulation occurred about 36 h after injection. The eggs of Yellow tang amyo buoyant and semi-transparent. The egg diameter range from 0.70 ± 0.06 mm . The eggs contain a single oil globule having a diameter of 0.17 ± 0.01 mm. Incubation period was approximately 42 h at the water temperature of 22.9 - 24.6 ℃ and salinities at 32 psu. The newly hatched larva was 2.17 ± 0.36 mm in length.
