영문 초록

To promote abalone production in aquaculture, we developed a new recirculatory culture system and its efficiency compared with flowing water system, and investigated of the growth rate of young abalone, Haliotis discus hannai on different kinds of shelters (polycarbonate-magnetic coated: PCM, plastic shelter, poly vinyl chloride: PVC). During experimental periods, range of water quality in recirculatory culture system was as followed, water temperature : 8.3~26.7℃, specific gravity : 1.0223~1.0268, pH : 7.35~8.81, DO : 5.06~5.80 ppm, NH4 : 2.24~4.48 ㎍-at/ l. Growth rate of shell length, 28.3%, of young abalone, H. discus hannai reared on PCM shelter was higher than on plastic shelter 24.3% and PVC shelter 23.7%. In weight ratio of a part to body weight of young abalone, H. discus hannai, meat and shell increasing weight ratio were 1.9% and 0.2%, but visceral weight ratio was decreased 2.1%. Survival rate of abalone, H. discus hannai in experimental periods was 97.33~98.28% in August~September, 98.93~99.30% in October~December, and average survival rate was 98.4%. Survival rate in autumn and winter was higher than in summer.
