Understanding the economic and biological status of a fishery resource is critical to designing efficient management policies. In one such attempt, this article assesses current and potential rents in the sole fishery in the English Channel. The sole fishery is found to experience rent dissipation due to significant disinvestment in the stock and substantial fleet overcapacity. The analysis also investigates alternative paths of attaining the optimal stock level.

This paper uses a bioeconomic modelling approach to show that for some optimal allocation of the mopane forest stock, the restrictive harvest period policy advocated by community leaders may not lead to sustainable harvesting of the worm.
