“…The behavioural assumptions of many models are unrealistic and little attempt has been made to assess the actual behaviour of firms engaged in strategic conflict over common property resources. In this respect Wilson (1982) presents a valid critique of conventional fishery economics and regulation and the post mortem on the catastrophic collapse of the Canadian Atlantic fishery (Roy, 1996;Tsoa, 1996) demonstrates the limitations of our current models of renewable resources.…”

The economics of renewable biological resources originated in the 1950s in fishery economics. The original models were static and linked simple population growth models to harvesting. In the 1970s the subject became more concerned with dynamic models and the stability of resource systems and this development continued in the 1980s. Now renewable resource economics is seen as a branch of capital theory which is distinct from mainstream capital theory because it must simultaneously represent the productivity of an ecosystem as well as the production functions of the firms which exploit it. Adding to this complex patterns of ownership over the resource itself and the dependence of production on the state of the ecosystem makes for a set of problems which economists have only started to address. Progress in renewable resource economics will come through closer collaboration with ecologists to give more realistic population models; the development of approaches for multi‐species ecosystems; and the use of modelling techniques and policies which can adapt as more information becomes available on the status of a resource. In the future renewable resource economics will continue to contribute to the sustainability debate by providing a clearer analysis of the trade‐off between ecosystem stability and the level of economic exploitation.

“…For example, between 1988 and 1992 about 868 000 t of fish were discarded annually in the Northwest Atlantic fisheries alone (Myers 1992(Myers , 1995; Food and Agricultural Organization of the United Nations 1995). Although the effects of evasive reporting have been well documented (Furlong 1991; Commission of the European Communities 1992; Crowley & Palsson 1992;Arai 1994), and the contributions of oceanic variables to declines in the total biomass of fish stocks are well known (Copes 1986;Myers 1992;Tsoa 1996), the VPA model scarcely utilizes such information in estimates of stock strength and calculations of total allowable catches. Failure in this regard contributes to incorrect estimates of fish mortality and optimistic predictions of the future abundance of stocks (Harris 1993;Lane & Palsson 1996;Roy 1996).…”

Despite steady injection of public funds by successive administrations, the Canadian fishery industry is characterized by resource depletion, vessel tie-ups, and overcapacity, which have led to plant closures and rising unemployment. This paper assesses the progress Canadian marine policies have been making towards rational use and conservation of fisheries and promotion of employment and economic development in fishing communities since 1977.The analysis begins with the creation of the 200-mile exclusive economic zone (EEZ) and its rationale in the United Nations Convention on the Law of the Sea (UNCLOS), namely conservation. State subsidies for fleet upgrading, industry modernization, marketing, and the introduction of quota systems, such as the individual transferable quotas (ITQs) and enterprise quotas (EQs), are identified as the key policy initiatives which might realize an economically-viable fishing industry in the post-1977 period. These policies produced corporate expansion and prosperity in the mid-1980s, but there followed corporate losses because of Canadian over-dependence on American markets and sharp quota cuts.With regard to conservation, shortcomings are identified in the virtual population analysis model (VPA), and the inability of the Department of Fisheries to monitor fishing effort by domestic and foreign vessels. The need for radical change in the future direction of marine policies is emphasized and arguments made which support the following objectives: elimination of ecologically-harmful fishing technologies; use of community quotas (with a modified individual quota system); strengthening of community management systems and development of co-management approaches to fisheries management, involving government and fishing communities.
