  • Description:
    Nori (Rorphyra sp.), an edible seaweed, produced in the experimental OTEC system at the Natural Energy Laboratory of Hawaii, Keahole Point, Hawaii was transported to Japan for processing into nori sheets. The resulting nori sheets were evaluated by qualified experts as a commercial product. Mostly due to damage when frozen for transport, the OTEC nori was judged to be of very low quality and worth about 6 yen (2.5 cents) per sheet if saleable at all. From the small amount of material that was undamaged in each sheet, the experts estimated the undamaged value at about twice, i.e. 12 yen (5 cents) per sheet. While this price may be considered low (an average Japanese nori sheet was purchased for about 20 yen (8.5 cents) this year), most of the Japanese experts emphasized that cultivating and processing high quality nori requires highly developed skills, favorable conditions and elements of luck, and that the Hawaii nori product was quite good for a "first try." They were optimistic that better [quality sheets could be produced in OTEC systems. Corrective techniques were suggested, but with most technical improvements additional costs would be incurred. These results indicate that more quality improvement research is required if nori is to be grown commercially in Hawaii. Researc​h on the production of nori (Porphyra sp.) in OTEC-like effluents has been conducted at the Natural Energy Laboratory of Hawaii (NELH) at Keahole Point, Hawaii during 1982. Biological feasibility of growing nori in these effluents was demonstrated. Preliminary economic analyses (Woessner, et al., 1981) were also performed. To do these analyses, certain assumptions was that OTEC nori could be sold for 11 cents per sheet. This study was undertaken to test the commercial quality and value of nori grown in OTEC systems. Quality is determined once the nori has been processed into sheets. The primary objective of this project was to determine the quality and value of nori produced in OTEC-like effluents. Machines and skills for making nori sheets occur only in the orient, primarily in Japan, as is the expertise for judging commercial value. Consequently, it was necessary to transport raw nori produced at the Natural Energy Laboratory of Hawaii directly to Japan for processing and evaluation.
