摘要

本實驗係以規則性絕食，卽以長短不同日數之絕食條件下飼育斑節蝦，其方法共計分為：每日投餌、3日投餌1日絕食、2日投餌1日絕食、1日投餌1日絕食、1日投餌2日絕食及1日投餌3日絕食等六種處理。目的在求出一種旣能節省餌料、人力又能提高成長率之極富經濟意義的投餌方法，獲得如下結果：
1．累積攝餌量隨絕食日數的增長而遞減，絕食日數在3天以內者，其平均一日攝餌率均隨絕食日數的增長而增加。
2．單位期間內之脫殼次數隨着絕食日數之增長而有減少之傾向，但每次脫殼後之增重率則隨着蝦體之大小及絕食時間之長短而有所不同。
3．此次採用之規則性絕食之投餌方法，對此蝦成長率之影響隨其成長階段之不同而異。綜言之，卽平均體重在0.71g左右之小型者，以每日投餌為最好；平均體重在2.86g左右者，以3日投餌1日絕食者為佳；平均體重在5.16g左右者，則以2日投餌1日絕食者為較好；至於平均體重9.45g左右者，則以1日投餌2日絕食者為最好。換言之，卽體型較小者，絕食時間宜短，較大者，絕食時間可較長。

並列摘要

Six kinds of periodic starvation were tried on Penaeus japonicus Bate, with an attempt to discover the most efficient feeding method. The results revealed that feeding daily was not necessarily the best method for promoting prawn growth. For different growth stages of P. japonicus, different ways of feeding would give better results. With such a feeding pattern, feed cost could be reduced and better growth obtained. The suitable feeding patterns obtained are:
1) for prawn with average body weight of 0.71g, feeding daily.
2) for prawn with average body weight of 2.86g, feeding three days followed by one day of starvation.
3) for prawn with average body weight of 5.16g, feeding two days followed by one day of starvation.
4) for prawn with average body weight of 9.45g. feeding one day followed by two days of starvation. The indication is, as prawns grow, starvation period could be longer.
