Pacific oysters (Crassostrea gigas), Alaska pink salmon (Oncorynchus gorbuscha) roe and chum salmon (Oncorynchus keta) fillets were treated with aqueous ozone in both pilot plant and commercial settings to determine its effect on shelf-life and microbial changes. The microbial quality was analyzed by conducting pyschrotrophic and coliform plate counts on 3M petrifilm. Oxidative rancidity, pH and moisture were measured during the shelf-life study to determine the effects of ozone on quality. Concentrations of 0.5-1.3 ppm of ozone were applied for periods of 30 s, 1, 2 and 4 min at 5°C, 9°C and 15°C to determine an optimum ozone concentration and contact time that would decrease the seafood microbial load and increase shelf-life in the pilot plant studies. Oysters and roe were treated at 15°C and 5°C and fillets were treated at 9°C. There where only minor microbial differences between ozonated and non-ozonated samples. Treatment temperatures rather than treatment types affected the microbial load. The pilot plant experiments at 15°C and 5°C showed 1 log decrease in oysters and roe treated with aqueous ozone at variable concentrations. No increase in shelf-life was observed when salmon fillets were treated with aqueous ozone (1.3 ppm) for 2 min. Bacteria strains were isolated from treated (ozone and water) and control salmon fillet groups at 0, 5 and 10 days of storage and identified using the API20 NE system. The microbial change in the fillet flora did not differ between ozonated and non-ozonated treatment groups. Gram-positive bacteria were predominant in all groups at day 0, Pseudomonas flunrescens and P. putida were the predominant bacterial species found from all groups at days 5 and 10. Aqueous ozone (0.5-1.7 ppm) was applied in a commercial Ikura roe processing facility. A decrease in the microbial load was seen in the pre-processed samples which were ozonated with eggs in the skein. There were no differences in microbial loads from the non-ozonated and ozonated post-processed samples of individual eggs removed from the skein. / Graduation date: 2003

By 1976 extended fisheries jurisdiction had been declared by most coastal states and territories of the world. The new regime of property rights was expected to affect seafood production costs which, in turn, could impact on seafood trade and the competitive positions of producing countries. In theory this policy should bestow upon coastal nations and territories a comparative advantage in seafoods. Thus, in studying price and nonprice competition as factors that influence seafood trade, a third factor (the effects of extended fisheries jurisdiction EFJ) is added. The best available data are aggregative. These data are used to analyze the influences of the three factors listed above on seafood trade. In the first part of the investigation, Canada and the U.S. are considered. The annual growth of each country's exports of fresh, frozen, and chilled fish to selected countries is computed using the constant market share approach. The calculated annual growth is partitioned into three effects (or components); namely; (1) competitiveness effect, which measures the portion of growth due to (price) competitiveness; (2) market distribution effect, which measures growth due to the (re)direction of exports to more rapidly growing markets; and (3) market size effect, which accounts for growth caused by overall growth in world demand. Both countries have gained substantial shares of the Japanese and European markets, but Canada's share of the U.S. market has declined due to increased competition from U.S. domestic producers. The U.S. share of every considered market has increased, in most cases, substantially. The second part of the study considers eight exporters of fish to the U.S. Various econometric models are used to analyze cause and effect relationships between changes in relative prices and changes in the market shares of pairs of countries/regions. Results indicate significant nonprice influence and symmetrical EFJ effects on product substitution. / Graduation date: 1987
