近年台灣地區水產養殖產業除了面臨天然條件改變之衝擊外，面對他國之競爭、食安意識普及等問題造成國內水產養殖產業於國際上之地位逐漸式微，為同時兼具產量與產品品質，應用友善養殖技術已成為近年重要的全球之發展趨勢，透過本研究調查與分析得知應用友善養殖管理技術後可有效提升四指馬鮁之單位面積生產量。以經濟層面分析，透過應用友善養殖管理技術後四指馬鮁每年估計可提升10.10公噸/公頃、227.46千元/公頃之產值及減少257.18 kWh/ha/month之耗電量，提升產值產量同時降低能源及成本之需求。進一步透過虛擬變數迴歸分析，影響單位面積生產量的正相關主要因素為放養密度、是否應用友善養殖管理技術及魚體收成規格，而育成時間越長卻不會得到較佳的單位面積生產量。本次調查結果確立應用友善養殖管理技術可提升養殖生產量、減少水與能源需求外，也間接降低人類對海洋造成之漁撈壓力、減少養殖廢水產生造成環境劣化之風險，促進展業永續經營與發展。

In recent years, the aquaculture industry in Taiwan has faced challenges not only from natural conditions but also from competition with other countries and increasing food safety concerns. As a result, the domestic aquaculture industry's position in the international market has gradually weakened. To simultaneously improve production quantity and product quality, the application of environmentally friendly aquaculture techniques has become an important global development trend. Through the investigation and analysis conducted in this study, it was found that the application of environmentally friendly aquaculture management techniques effectively enhances the unit area production of Fourfinger Threadfin. From an economic perspective, the application of these techniques is estimated to increase the annual production value of Fourfinger Threadfin by 10.10 tonnes/ha and 227.46 thousand NTD/ha , while reducing the electricity consumption by 257.18 kWh/ha/month. This increase in production value and quantity, coupled with reduced energy and cost requirements, demonstrates the benefits of adopting environmentally friendly aquaculture practices. Further analysis using regression models with dummy variables revealed that stocking density, the application of environmentally friendly aquaculture management techniques, and fish harvest size specifications are the main factors positively correlated with unit area production. However, a longer rearing period does not necessarily result in higher unit area production. The findings of this survey confirm that the application of environmentally friendly aquaculture management techniques can enhance aquaculture production, reduce water and energy demands, indirectly alleviate fishing pressure on the oceans, mitigate the risks of environmental degradation caused by aquaculture wastewater, and promote sustainable growth and development in the industry.
