短腕岩蝦 (Periclimenes brevicarpalis Sehenkel, 1902) 是一種可與海葵共生的海水觀賞蝦，為了開發量產技術，本試驗先建立人工繁殖的相關技術，探討種蝦生殖週期及孵化時間與水溫的關係，初期蝦苗 (蚤狀幼體一至四期) 投餵餌料密度、餵食時機、溫度及鹽度對成長及活存的影響。初步結果顯示種蝦生殖週期與水溫呈負相關，孵化積溫為284.0 ± 51.2度日，初期蝦苗 (孵化後6天) 的餌料密度以豐年蝦無節幼蟲4隻/ml以上有較佳活存率及成長。延遲1天投餌不利蝦苗活存。溫度方面，蝦苗在24–33°C的水溫環境下活存率較佳，而成長則以27–33℃較佳。鹽度方面，蝦苗在19–34 psu的鹽度下其活存率較佳，而成長則以19–39 psu較佳。綜合以上，本研究顯示短腕岩蝦蝦苗培育在27–33℃，鹽度19–34 psu，孵化當日餵食4隻/ml以上豐年蝦，可以在孵化後15–43日發現變態為底棲性的後期蝦苗。

摘要abstract(英) Periclimenes brevicarpalis Sehenkel, 1902, known as the spotted cleaner shrimp, is a marine ornamental shrimp that forms symbiotic relationships with sea anemones. This study aimed to establish artificial breeding techniques by investigating the broodstock’s reproductive cycle and the effects of water temperature on hatching time. It also assessed the impact of feed density, feeding timing, temperature, and salinity on the growth and survival of early-stage larvae (zoeal stages I-IV). Preliminary results showed that the broodstock’s reproductive cycle was negatively correlated with water temperature, with a cumulative hatching temperature of 284.0 ± 51.2 degree-days. Early-stage larvae (6 days post-hatching) had the best survival and growth at a feed density of over 4 Artemia nauplii per ml; delaying feeding by one day reduced survival. Optimal survival occurred at 24-33°C, and optimal growth at 27-33°C. Salinity ranges of 19-34 psu supported better survival, while 19-39 psu promoted optimal growth. In conclusion, rearing larvae at 27-33°C and 19-34 psu salinity, with over 4 Artemia per ml on the hatching day, supports metamorphosis into benthic post-larvae within 15-43 days post-hatching.
