本論文之目的是研究條紋蝦魚 (Shrimp Fish, Aeoliscus strigatus) 之人工繁殖技術，以因應觀賞魚產業發展之需求。自2004年8月6日至2005年8月5日止，種魚投餵三種餌料包括糠蝦、橈足類及豐年蝦無節幼蟲，結果以投餵糠蝦組之活存率為 86.7% 最高，而豐年蝦無節幼蟲組 56.7% 最低，三組間活存率皆有顯著差異。條紋蝦魚產卵行為發生於11月，產卵水溫介於 24 ~ 30 ℃，當水溫低於24 ℃ 以下，產卵行為即停止。種魚每日產卵時間為 18：30 ~ 20：30，每次產卵數約 1 ~ 43 顆，受精卵為圓球型、透明之浮性卵，卵與卵間有透明膠質相連成鏈條狀，卵徑 1.10 ± 0.06 mm，油球數 1 個，油球徑 0.23 ± 0.04 mm，在水溫 24.8 ± 0.8 ℃ 下約 32 小時孵化，剛孵化仔魚體長為 2.62 ± 0.12 mm。孵化之仔魚具趨光性，隨著成長，仔魚驅光性變弱。孵化後 1 ~ 12 日間，投予輪蟲，第 13 日起，即可兼投橈足類，第 20 日以後完全投予橈足類，孵化後第 28 日，魚苗之全長為 6.25 mm，育苗期間水溫在 24.0 ~ 27.0 ℃。

This study was to understand the processes in early life history of the shrimpfish (Aeoliscus strigatus)in captivity. The Neomysis was the best feed for broodstock compared with copepod and Artemia. Spawning started from 18:30 to 20:30, with about 1-43 eggs per spawning. The spherical eggs were about 1.10 ± 0.06 mm (n = 30) in diameter, with an oil droplet of 0.23 ± 0.04 mm in diameter. The newly hatched larvae were about 2.62 ± 0.12 mm in total length (The fertilized egg took 32 h to hatch under 25 ± 1^oC ) and were fed with rotifers from day one post hatching (1 DPH) to12 DPH. On 13 DPH, copepod was supplied as the feeds and gradually increased until it totally replaced rotifers on the 20 DPH. The 28 DPH old fry were about 6.25 mm in total length.
