為了建立油彩蠟膜蝦 (Hymenocera picta) 之人工繁殖技術,本試驗探討不同的餌料密度、延遲餵食、鹽度及溫度對初期蝦苗成長及活存的影響。在水溫27 ± 1℃的環境下,初期蝦苗的餌料密度以投餵 2和4隻/ml豐年蝦無節幼蟲對孵化後10天的蝦苗有較佳活存率及成長。延遲餵食結果顯示蝦苗孵化後2天內餵食,有較佳的活存率及成長。而蝦苗飼育在鹽度24 ~ 39 psu的環境下活存率較佳。溫度方面,蝦苗在24 ~ 30 ℃的水溫環境下有較佳的活存率,而成長則以30℃較佳。本次試驗結果顯示:將油彩蠟膜蝦苗飼養在水溫30 ℃、鹽度24 ~ 34 psu,且於孵化後2日內餵食密度2 ~ 4隻/ml豐年蝦無節幼蟲,將會有較佳的成長及存活率。

摘要abstract(英)


To develop aquaculture techniques of Hymenocera picta, the effects of different types of diets, feeding concentrations, starvation, temperatures and salinities on the growth and survival were investigated. The result showed that 10 dph (days posthatch) larvae feeding with the nauplii of Artemia spp. at 2 and 4/ml of feeding had better survival rate and growth. About the delay of feeding, better survival rate and growth would be obtained under feeding within 2 dph. The survival rate was better in which salinity was at 24, 29, 34 and 39 psu. In addition, a better survival rate was obtained in which were raised during the water temperature of 24 ~ 30 ℃, but better growth was obtained at 30 ℃. Overall, the shrimp would have better survival rate and growth under conditions of 30 ℃, 24 ~ 34 psu, and feeding with the nauplii of Artemia spp. at 2 ~ 4/ml within 2 dph.
