The paper examines howan easy-to-apply optimal feedback rule can be used to solve for optimal levels of exploitation of a renewable resource. Using data from Canada's northern cod fishery, the optimal feedback rule is used to derive optimal levels of exploitation for the years 1962–91 under...

The economic efficiencies of the Danish, Icelandic, and Norwegian cod fisheries are examined. For this purpose, nonlinear aggregate models of these fisheries are constructed. Comparing the calculated optimal harvest and biomass quantities with the actual fisheries provides a measure of the...

The failures of traditional target-species management have led many to propose an ecosystem approach to fisheries to promote sustainability. The ecosystem approach is necessary, especially to account for fisheryï¾–ecosystem interactions, but by itself is not sufficient to address two...

<DIV>As we search urgently for a strategy of sustainable natural resource management, an international debate is brewing over destructive modern fishery methods. <I>Namibia's Fisheries</I> is a timely contribution to this discussion as it examines Namibia’s Benguela upwelling system, an area that supports...</i></div>

A non-linear dynamic model in two state variables, two controls and three cost terms is presented for the purpose of finding the optimal combination of exploitation and capital investment in optimal renewable resource management. Non-malleability of capital is, in other words, incorporated in...

In the North Atlantic the Icelandic, the North Sea, and the Newfoundland cod stocks are currently overexploited. Overexploitation also characterised the Northeast Arctic cod stock, but effective management measures introduced in 1990 and the years thereafter have brought this stock within safe...
