臺灣西半部沿海盛行牡蠣養殖，潮間帶與潟湖區域因容易受到海岸地形與氣候變化影響，使牡蠣產量不穩定，產值無法提高。本研究以臺南市北門潟湖為研究場域，由養殖方式與銷售形態兩方面評估現行產業狀況，提出牡蠣養殖改善策略，有助漁民提升牡蠣養殖效益。
以養殖方式改善而言，本研究於2018年6月至2019年11月於研究場域內使用塑膠籃與袋網兩種容器，將傳統蚵串型式的牡蠣剝離為單體，置於容器中進行單體牡蠣養殖實驗。研究結果顯示塑膠籃單體牡蠣之成長速率高於袋網養殖，可長期蓄上培育大個體牡蠣提高價格，也可避免牡蠣業者採收時間集中造成供需失衡現象，達到提升養殖經濟效益目的。在行銷策略評估方面，本研究分析臺灣中央與地方法規及水產養殖管理委員會(Aquaculture Stewardship Council, ASC)認證制度得知，牡蠣養殖業引進ASC認證可拓展國內外銷售市場，但目前臺灣在7大類ASC行銷標準達成率僅有45%，尚難推動牡蠣養殖之ASC認證。因此，本研究提出之改善策略為由中央政府設立基金與制定規範，鼓勵讓養殖戶進行養殖培訓課程外，也可幫助企業輔導養殖戶接受國外認證，再由地方政府進行地方法規修法協助建構牡蠣生產管理制度，期望能改善牡蠣養殖業所面臨問題，以達成整體效益改善之目標。

In this study, two receptacles, plastic case and net cage, were used to rise single individual of oyster for improving the efficiency of oyster farming, the approach were counducted in different locations over periods of 5 months and 8 months starting in June 2018 and April 2019. It was revealed that plastic cases can provide larger individual of oyster than net cages that can increase the selling price. In additionly, receptacles can be used to modulate production of oyster while most of farmer harvest oyster during the saem period..
With regard to marketing feasibility, Taiwanese laws and local regulations were compared with Aquaculture Stewardship Council (ASC) standards to reveal the difficulties currently faced by aquaculture farmers and the government.
The results of the study show that at present, only 45% of the 7 major ASC marketing standards was regulated by the Taiwan government, and thus certification is still unavailable. Therefore, the improvement strategy proposed in this study makes several recommendations. First, the central government should establish funds and formulate regulations. Second, enabling aquaculture farmers to conduct farming training courses, the funds could aid private companies to guide aquaculture farmers toward ASC certification. Finally, the local government should modify local regulations. Implementing these recommendations is expected to ameliorate the problems faced by the oyster farming industry and to achieve the goal of improving overall efficiency.
