建構整合型多營養階利用養殖系統，利用不同生物特性進行混養養殖和彼此生 物及吸收不同營養特性，型成一個互利的生態系統。應用此互利的生態養殖模式可 減少在產品養殖過程中對環境的衝擊破壞避免大量耗水和污染環境，達到生態養殖 的觀念。本年度擬應用鹹水整合型多營養階利用養殖系統，組合黃鱲鰺、牡蠣和龍 鬚菜養殖，並添加光合菌輔助水質，建立黃鱲鰺於系統中的養殖模式，並評估其養 殖效益。發展對環境友善養殖系統，以生產安全水產品，提升產值促進產業升級。 應用整合型多營養階利用養殖系統，組合魚類、牡蠣和龍鬚菜養殖，並添加光合菌 輔助水質。經過3 0 天養殖， 放養黃鱲鰺體重65.3±9.6g、體長13.1±0.7 cm到體重 95.9±17.8g、體長18.1±1.2 cm。監測水質環境，魚蝦池pH、溫度、鹽度、透明度、 溶氧均在適合養殖範圍內，氨氮、亞硝酸氮濃度均在安全濃度以下。

Through combining the cultivation of finfish with Gracilaia and oyster, we have successfully established integrated multi-trophic aquaculture (IMTA) system. Furthermore, photosynthesis bacteria were used to improve the water quality. After 13days of rearing, the growth in weight (total length) of milkfish increase from 22.4±6.4 g to 53.0±12.6 g (14.3±1.2 cm to 17.8±1.3 cm) in in the northern system and the growth in weight (total length) of pompano increase from 65.3±9.6g to 95.9±17.8 g (13.1±0.7 cm to 18.1±1.2 cm) in in the northern system. Finally, during the period of experiments, pH, temperature, salinity, transparency, dissolved oxygen in fish ponds are suitable for breeding, and ammonia nitrogen, nitrite nitrogen concentrations are also below the safe concentration.
