本試驗主要目的在比較不同濃度之腎上腺素濃度處理及貝殼砂對單體牡蠣種苗之誘發試驗,並探討漁塭養成之可行性。試驗主要為三部份:(一)取330-350μm之牡蠣幼苗,利用0.05mM、0.1mM、0.2mM之腎上腺素處理1小時,經48小時後觀察變態率。(二)試驗分四組,分別為腎上腺處理組、貝殼砂(0.3μm)組、貝殼砂加腎上腺處理組、對照組,比較單體牡蠣之誘發率。(三)取單體牡蠣,於室內池養至0.3公分後,再置田間池及室內繼續蓄養,每兩星期紀錄殼長、總重、肉重及肥滿度及死亡情形。

研究報告摘要(英)


The purpose of this experiment is to compare different concentration of epinephrineand shell debris for inducing clutchless oyster and discuss the posibility pond culturesystem.The experiment divided three parts:(1)At the larvae reached to 330-350μmperiod,treated with 0.05 mM,0.1mM,0.2mMepinephrine for one hour,after 48hours,to discuss the effect of epinephrine on the metamorphosis of oyster larvae.(2)Tocompare the metamorphosis for four groups,epinephrine,shell debris,epinephrine andshell debris,control.(3)Transfer the 0.3cm clutchless oyster into pond culture and indoorsystem.The shell length,total weight ,body weight,condition factor and mortality will bemeasured in every two week.
