本研究為瞭解國內石斑魚運銷通路與運銷成本的情況，同時預測未來國內市場對石斑魚的需求，乃透過問卷調查方式，以及運用灰色預測理論來進行分析。運銷通路的問卷進行係以2012年為基準年，總計回收47份問卷，結果發現養殖戶主要銷售給販運商與批發商，顯見通路結構仍為少數販運商所控制，出口方面約占總產量的72%，國內消費市場約占28%。在通路益本分析方面，則係以批發商的益本比1.1864為最高，加工廠1.0966次之。另外，在市場需求預測研究方面，透過灰色預測模型結果顯示，臺灣石斑魚的需求量呈現逐年上升之趨勢，增加率介於10-20%。基此，政府與業界可積極改善石斑魚的運銷效率，以及協助養殖漁民與通路業者持續開拓石斑魚內需市場，讓國內消費者更多認識石斑魚的特性與營養價值，強調產品優勢以提升國內市場對石斑魚之需求，擴大國內石斑魚市場的永續發展空間。
