Evolution of Profitability and Fisher Attitudes 1990 - 2000 in the Irish Sea, - an Overfished Fishery

Creator:: Hillis, J. P.
Abstract:: The Irish Sea, being an area fairly discrete and partially isolated from adjoining fishing grounds, lends itself well to research studies. The area is fished by Ireland and the United Kingdom, with limited effort by France and Belgium, and has been known to be overfished for quite a long time....

Abstract:: In developed country markets, the consideration of consumer wants has not been prominent hitherto in aquaculture production decisions. Like capture fisheries aquaculture has been product driven. This supply-side focus reflects an emphasis upon technical solutions to the production and capacity problems of high unit value (HUV) species culture. Whilst this...
