"九孔孵化池加入各種不同濃度的臭氧對附苗板上的附著藻及九孔苗的活存之影響。 (一) 正確定量臭氧濃度，並能正確指出多少臭氧濃度方能抑制細菌而不影響矽藻的附著量，降低細菌量而提高九孔苗的活存率。 (二) 探討矽藻相與量與細菌之消長現象。" "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, the breeding technology of larvae and the adult abalone, but also elevates the mass production amounts to 2400 Mt annually capacity for the small abalone. However, mass mortality of juvenile abalone occurred two 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. If the mass mortality of juvenile abalone can not be solved, this industry will be disappeared. Therefore, we must find a way to solve the mass mortality problem of small abalone.
The purpose of this study will examine the effects of ozone on the survival of small abalone postlarvae. There will have two objectives: (1) to inhibit the level of Vibrio in the plastic plate and remain high survival of small abalone postlarvae, the ozone abailable concentration should be determined; (2) The effects of ozone concentration on the quality and quantity of benthic diatom."
