| Summary: | Dissertation (Ph.D.) University of Alaska Fairbanks, 2011 Spiny dogfish is a valuable commodity on the world market and has a global capture distribution. There are three chapters evaluating dogfish markets and fisheries in this dissertation; Chapter 2 evaluates the spatial distribution of dogfish in the Gulf of Alaska; Chapter 3 provides an overview of world markets and evaluates conditions that have led to a decline in dogfish product demand in Europe; and Chapter 4 uses the information from the previous 2 chapters to provide and policy and market overview of dogfish fisheries in Alaska. Results from this study provide a comprehensive world overview of the modern dogfish fisheries and market segmentation using an evaluation of trade and price statistics. These results indicate that the dogfish market is adulterated, supplied by both sustainable and non-sustainable dogfish sources. Media attention resulting from overfishing has reduced demand for dogfish products in Europe due to the adulterated market. Overcoming the loss of market share will require eco-labeling to inform consumers about sustainable dogfish stocks. The impact of eco-labeling in Asian countries is less clear due to unknown inter-Asian market channels for fins and meat and little information on consumer attitudes towards labels. Alaska products could leverage either Asian or European consumers, but a profitable fishery will likely require regulatory changes and improved stock assessment to allow a directed fishery. In addition, pending regulatory changes, establishing robust market channels between Alaska and Europe will likely require some form of eco-labeling; especially given current eco-labeling efforts in Canada and the Atlantic US.
