為了建立亨氏活額蝦 (Cinetorhynchus hendersoni) 的人工繁殖技術,本試驗探討不同的餌料密度、餵食時機、鹽度及溫度對初期蝦苗成長及活存率的影響。在水溫27 ± 1℃ 的環境下,初期蝦苗以0.5或1隻/ml豐年蝦無節幼蟲餵食的活存率高於其它密度,投餵1、2或4隻/ml豐年蝦成長至第五期蝦苗的時間無顯著差異;延遲投餌對活額蝦苗活存率有不利的影響,延遲1日投餵的蝦苗成長至第五期蝦苗的時間顯著延長且活存率顯著降低 (p ≦ 0.05);蝦苗飼育在鹽度24 ~ 39 psu的環境下成長速度無顯著差異,但以34 psu 的活存率最高;蝦苗在24 ~ 30℃ 的水溫環境下活存率高於其它溫度,而達到第五期蝦苗的時間則以30及33℃ 最短。本次試驗結果顯示亨氏活額蝦初期蝦苗飼養在水溫30℃、鹽度34 psu,且於孵化後即時餵飼1隻/ml豐年蝦無節幼蟲,將會有最好的成長及存活率。

摘要abstract(英)


Cinetorhynchus hendersoni (Kemp 1925) is a kind of ornamental shrimps in the special ecological status which may coexist with other ornamental creatures. For the development of artificial culture techniques of C. hendersoni, the effects of food, starvation, salinities and temperatures on growth and survival rate were investigated. Better survival rate and growth were obtained under a feeding scheme with the nauplii of Artemia at 1/ml from newly hatched to the 5th stage zoea. Survival rate and growth decreased as larvae were not fed on the first day post-hatch. The growth was better in which were raised at 24, 29, 34 and 39 psu, but survival rate was better at 34 psu. Better survival rate of the dancing shrimp was raised between 24 ~ 30℃, and better growth was obtained at 30 and 33℃. Overall, better survival rate and growth would be obtained under raising at 30℃, 34 psu, and feeding with the nauplii of Artemia at 1/ml starting from the first day after hatching.
