"九孔孵化池施以臭氧處理並在附著板上添加人工微粒飼料，觀察附著板上的九孔苗活存與成長。
（一）殺菌的過程中，附著板上仍有餌料為九孔苗攝食，方能確保九孔苗的成長與活存。
（二）突破性的開發九孔苗的人工飼料。
（三）確保九孔產生的永續經營。" "Small abalone aquaculture emerged in the late 1970s on a very small scale in Taiwan. Now, abalone aquaculture is an economically important gastropod in Taiwan. It has not only been successfully developed the breeding of the small abalone, but also elevates the mass production amounts to 2400 Mt annually capacity for the small abalone. However, mass mortality of juvenile abalone occurred three years ago. Attached juvenile abalone fall down from plastic plate after 7 to 14 days attachment. It means that farmer will not have juvenile abalone to culture. The outbreak of Vibrio in the plastic plates causes the mass mortality of small abalone juvenile. We find a suitable way to inhibit the Vibrio levels in the plastic plates by using ozone to treat the water.However,the ozone treatment aso inhibits the natural diatom growth in the plastic plates. The small ablone juvenile faces the lack of food. We must estabish a way to solve the bacteria and food problems for small abalone.
The purpose of this study will exam the effects of microparticulate diets on the survival of small abalone juvenile. There will have two objectives:1) to devlope a suitalbe microparticulate diet for small abalone juvenile, 2) to observe the effects of microparticulate diet on the survivalof small abalone."
