摘要

本實驗連續五天日夜不同時段採集體長介於10.55 mm至31.55 mm的野生花身雞魚(Terapon jarbua)稚魚，記錄各時段之胃內容量變化與主要餌料在魚胃內的出現頻率。其胃容量/體重(SCW/BW)的比値從凌晨4:00的2.45％開始上升，在14:00達到最高峰，即9.93％而後開始下降；具有規則的日夜變動趨勢。並且以橈足類(Copepods)為主要食物來源，在魚胃內的出現頻率高達83.09％，並與其胃容量/體重的比値有相似的日夜變動趨勢。

Juvenile thornfish(Terapon jarbua)were collected at intervals of two hours for a108-hour period from July 1 to 5,1993.Stomachs with contents were weighed,and fooditems were analyzed to determine their feeding rhythm.There was a stereotypical diurnalfeeding rhythm with the maximum(peak)in the afternoon(14:00)and the minimum(emptystomach)in the night before sunrise.Copepods were the most dominant prey(83.09%of occurrence frequency),which was followed by chlorophytcs(29.44%)and decapods(24.10%).The frequency of occurrence of copepods corresponded with the feeding rhythm.
