為瞭解花身雞魚(Terapon jarbua)軀幹肌肉之生長發育機制與各種肌纖維在肌肉生長過程中的轉變，本實驗利用已建立之組織化學分類技術來研究不同發育階段：稚魚期、幼魚期、成魚期之花身雞魚軀幹肌中白肌、紅肌及粉紅肌之各種肌纖維的組成與分佈變化，同時對各發育階段中肌纖維之代謝型式及能量來源進行探討。 研究發現花身雞魚白肌之肌纖維是由原先即已存在之小CSA(cross-sectional area)的type IIb fibers以細胞增大(hypertrophy )的方式成長；紅肌則表現出是以細胞增殖(hyperplasia )的方式成長，大量IIc fibers的存在顯示紅肌具有很高的分化能力；粉紅肌細胞數目的增加，主要是靠紅肌中之肌纖維的移出，此移出現象在經過粉紅肌之後，轉變為type IIb fibers的細胞便加入白肌之中，因此在花身雞魚的成長發育過程中，粉紅肌可能扮演一個「過渡」或「中間者」的角色。 The present study investigated the contribution of fiber hypertrophy and hyperplasia to the growth of white, red and pink muscle in the tigerperch, Terapon jarbua during different development stages. Histochemical techniques were used to examine the muscle fiber type, metabolic properties and energy sources. In the white muscle fibers, growth was contributed from the increasing small CSA (cross-sectional area)type IIb fiber hypertrophy .The muscle growth is expressed as the muscle fibers hyperplasia. The amount of type IIc fibers within red muscle indicate the red muscle with highly development ability. Pink muscle is probably a growth stage of other muscle patterns, increases the number of pink muscle fibers due to the development transition from the red muscle fibers. Thus, the pink muscle may play an “intern1ediate" in the trunk muscle development of tigerperch.
