以橈足類、滋養豐年蝦幼生、豐年蝦幼生及市售人工配合飼料四種餌料，探討庫達海馬(Hippocampus kuda) 幼苗的成長及活存率。經過28天育苗試驗結果顯示，投餵橈足類組，其活存率為85.67 ± 1.16 %，極顯著優於其他滋養豐年蝦幼生、豐年蝦幼生和市售人工配合飼料各組 (活存率分別為45.00 ± 5.00 %、26.67 ± 6.11 %，其中市售人工配合飼料組第7天已全數死亡) (p < 0.001)，且滋養豐年蝦幼生組亦極顯著優於豐年蝦幼生組 (p < 0.01)。至於成長方面，同樣是以橈足類組之體高 (46.94 ± 2.83 mm) 極顯著優於滋養豐年蝦幼生及豐年蝦幼生組 (26.60 ± 3.17 mm及24.53 ± 3.01 mm) (p < 0.001)，而滋養豐年蝦組亦顯著優於豐年蝦幼生組 (p < 0.05)。庫達海馬幼苗養殖結果說明橈足類不論在嗜口性或是營養價均優於滋養豐年蝦幼生，而人工配合飼料目前無法取代活餌。

Cultured copepod, enriched Artemia nauplii, Artemia nauplii, and artificial feed were fed to make comparision of the growth and survival of newborn Hippocampus kuda. After a 28-day rearing period, the survival of Hippocampus kuda juveniles fed copepod was 85.67 ± 1.16%, and was significantly higher than those fed enriched Artemia nauplii (45.00 ± 5.00%), Artemia nauplii (26.67 ± 6.11%), and artificial feed (all seahorses were dead within 7 days). The survival of juveniles fed enriched Artemia was significantly higher than those fed unenriched Artemia. The mean body height of juveniles fed copepod (46.94 ± 2.83 mm) was also significantly higher than those fed enriched Artemia nauplii (26.60 ± 3.17 mm) and unenriched Artemia (24.53 ± 3.01 mm). Similarly, the mean body height was significantly higher in juveniles fed enriched Artemia than fed unenriched Artemia. Based on the results of this study, the cultured copepod is better than the enriched Artemia nauplii, in terms of palatability and nutrient value, however, current artificial feed cannot substitute the living feeds.
