The remaining connected open set Ω we call the spiny urchin.

The ecosystem approach is necessary, especially to account for fishery–ecosystem interactions, but by itself is not sufficient to address two important factors contributing to unsustainable fisheries: inappropriate incentives bearing on fishers and the ineffective governance that frequently exists in commercial, developed fisheries managed primarily by total-harvest limits and input controls. We contend that much greater emphasis must be placed on fisher motivation when managing fisheries. Using evidence from more than a dozen natural experiments in commercial fisheries, we argue that incentive-based approaches that better specify community and individual harvest or territorial rights and price ecosystem services and that are coupled with public research, monitoring, and effective oversight promote sustainable fisheries.

A general answer is the expected reproductive success of the individual; i.e. mean individual fitness. This basic fitness maximization principle underlies much of the modern evolutionary theory of adaptation (Fisher 1930, Williams 1966, Maynard Smith 1978). Criticism of the hypothesis of fitness maximization has, however, also been widespread (e.g. Dupre 1987).

Among the principal predictions of the analysis are: (a) total catch quotas do not improve the economic performance of an open-access fishery; (b) limited entry results in distortion of inputs unless every input is controlled; (c) taxes and allocated transferable catch quotas are theoretically equivalent to one another in terms of economic efficiency, and both are capable in principle of optimizing exploitation of the common-property fishery.Key words: economics, fishery regulation, management, quotas, licenses, taxes, fishermen's quotas, common-property resource
