水產研究(1993年創刊)-淺蜊人工繁養殖之初步研究
主題: 淺蜊人工繁養殖之初步研究
摘要(中):
本研究針對淺蜊 (Tapes literatus) 進行人工繁殖以及稚貝培育試驗,除觀察其胚胎發育,也探討鹽度遽變 (0、5、10、15、20、25、30、35、40、45 psu) 對稚貝活存率的影響。水溫28 C、鹽度32 psu條件下,受精卵於受精後1.5 hr分裂成二細胞期;4 hr後進入四細胞期;6 hr後進入八細胞期;8.5 hr進入十六細胞期;10.5 hr後進入三十二細胞期;12 hr後進入桑椹期;14 hr後進入囊胚期;17 hr後進入擔輪子期;31 hr後發育成面盤 (D型) 幼生;9天後發育成具足面盤幼生;15天後進入沉底苗。培養在33 psu海水的淺蜊直接放入10 psu以下的海水中72 hr後,其活存率均為0;15 psu時為76.6%;20 ~ 30 psu時為100%;35、40、45psu的存活率則分別為96.6%、93.3% 及80%。

摘要abstract(英): This study conducted an experiment on artificial propagation of Venus clams, Tapes literatus and cultivation of juvenile clams. In addition to the observation of embryonic development, the effects of abrupt salinity changes (0, 5, 10, 15, 20, 25, 30, 35, 40, 45 psu) on survival rates of juveniles were also examined. At water temperature of 28℃ and salinity of 32 psu, fertilized eggs of T. literatus developed into 2-cell stage 1.5 hours after fertilization, 4-cell stage after 4 hours, 8-cell stage after 6 hours, 16-cell stage after 8.5 hours, 32-cell stage after 10.5 hours, Morula stage after 12 hours, Blastula stage after 14 hours, Trochophore stage after 17 hours, Veliger stage (D-shaped larvae) after 31 hours, Pediveliger stage after 9 days, and settled juveniles after 14 days. The survival rate of juveniles cultured in 33 psu water was 0% after 72 hours after being transferred to salinity of 10 psu. The survival rates after 72 hours were 76.6% at salinity of 15 psu, 100% at salinity of 20-30 psu, 96.6% at salinity of 35 psu, 93.3% at salinity of 40 psu, and 80% at salinity of 45 psu.
