This paper explores the possibility of using marine reserves to protect stocks subject to bycatch problems. The importance of migration rates and growth rates of both target and bycatch species and costs are analyzed. Pure open access equilibrium harvest of target species and stock level of bycatch species are compared...
A non-linear, parabolic type, mathematical model is presented, simulating the movement of an organophosphate insecticide, Vapona, in plasticized polyvinyl chloride (PVC). The molecular transport of diffusant in the polymer matrix and its subsequent desorption from the surface have been characterized in terms of the integral rate coefficient for diffusion and...
This paper discusses the potential application of implicit discount rates (IDR) derived from Individual Transferable Quota (ITQ) trading data as indicators of fishery bio-economic health. The theoretical background is discussed, and in the context of one New Zealand ITQ fishery we analyze the behavior of IDR over ten years of...
Global warming is expected to affect the ecosystem in the Northeast Atlantic, and sufficient changes will also affect
the aquaculture industry. Farming of salmon and trout is the biggest aquaculture industry in Norway. The export
value was about 2 billion US dollars in 2005. The objective of the paper is...

To determine if diet affects the growth rate of juvenile ling cod, we began with three initial objectives: 1) Record the growth rates of juvenile lingcod on different diets (squid and sardine); 2) Determine if hemocyanin will cause lingcod skin and muscle pigmentation will take on a...

The extent to which demand and supply shocks are transmitted in the value chain is an important topic. As many value chains cross international borders exchange rate pass through is an important element in this context. In this paper a multivariate system that allow us to test different hypothesis with...
Many Fraser River sockeye salmon stocks show large cycles in abundance from year to year, but the causes of these
cycles are not clear. As a result, these stocks have historically been managed under the hypothesis of cyclic dominance,
i.e., maintaining the cyclic behaviour of the stocks. Biological studies and...
