至以色列進行研究訪問，參訪國家海水養殖中心、班科隆大學沙漠研究所群、微藻養殖公司N.B.T.杜氏藻生產場及Algatech微藻養殖場、Sakura Ltd.海藻生產場、海水魚苗與養殖公司Ardag魚苗繁殖場及Madan魚苗繁殖與錦鯉養殖包裝場，研習其先進藻類養殖及魚貝藻多營養階永續養殖法，以及尋找可用海洋深層水開發之藻類產業。在台灣探討溫光鹽及營養鹽對3種矽藻增殖之影響，顯示光照影響顯著，可應用以分離保存藻原來接種，調光來控制矽藻膜發展。試驗鹽度、有機及無機營養鹽以及密度對龍鬚菜新芽之影響，顯示20 psu低鹽有較佳增殖，而20-35psu及0.5-1.0g/l密度下有8-10 %/d增殖率。此種成長快速的龍鬚菜新芽將可應用於作為後期九孔幼苗的食物。

To learn the advanced technique for microalgae culture and Seaweed-based integrated mariculture in Israel and hope to find the potential algal industry using the deep seawater in Taiwan, I visited National Center for Mariculture, Bengurion University of the Negev, Jacob Blaustein Institutes for Desert Research, Nature Beta Technologies, Algatech, Sakura Ltd., Ardag fish hatchery- Ardag Red Sea Mariculture and Maagan Michael Fish Breeding Center. The effect of temperature, light, salinity and nutrient on the growth of three diatom showed the most important factor was the light. Light could be used to control the diatom film development when use the preserved stock culture as seed. The effect of salinity, algal density and nutrients on the growth of Gracilaria germlings indicated low salinity (20 psu) was better and the high growth rate (8-10 %/d) imply it could be the optimal food for the juvenile small abalone.
