| 内容記述 | Deep seawater (DSW) is natural resources of little value compared with fossil fuels, but it was unlimited resources. DSW is expected to make efficient use of infinite natural resources. DSW has been pumped up from a depth of 320m and 340m off Kochi Prefectural Deep Seawater Laboratory in Muroto, Japan. The characteristic of DSW is that its temperature (ca 12℃) is lower than surface seawater throughtout the year. The nutrient contents of DSW such as, dissolved inorganic nitrogen (DIN)(12.1-26.0μM) and dissolved inorganic phosphates (DIP)(1.1-2.0μM) were higher than surface seawater (DIN:0-5.4μM, DIP:0-0.5μM) in Muroto. The concentrations of pathogenic microorganisms in DSW are also much lower than surface seawater (Yamaguchi et al. 1994). Because of these characteristics, DSW consider to be a valuable source for mariculture of seaweed and shellfish (Roels et al. 1975).A large amount of seaweeds is needed for abalone, Hariotis sieboldii, culture. However, the seaweed as food for abalone can't be collected from the natural sources anytime and anywhere and artificial foods for abalone are very expensive. Therefore, new method of seaweed cultivation in the tank is necessary. In this study, a new method of seaweed cultivation is designed with free living form "germling cluster" of brown kelp in the laboratory and outdoor tank using DSW. As the sporophytic germlings were connected by holdfast in this method, free floating form can be cultured in the tank.The present thesis deals with, 1) establishment of the mass tank culture systems of brown kelps (the "wakame" Undaria pinnatifida and the "hosomekonbu" Laminaria religiosa) using DSW, 2) examination of the growth of abalone fed on Undaria pinnatifida and Laminaria religiosa, 3) disscussion of the polyculture system between the abalone and brown kelp using DSW. | |||||
