Sammendrag
A biomass model of a wild salmon (Salmo salar) river recreational fishery is formulated, and the ways in which economic and biological conditions influence harvesting, stock size, profitability, and the benefit of the anglers are studied. The demand for recreational angling is met by fishing permits supplied by myopic profit-maximizing landowners. Both price-taking and monopolistic supply is studied. These schemes are contrasted with an overall river management regime. Gear regulations in the recreational fishery, but also the commercial fishery, are analysed under the various management scenarios, and the paper concludes with some policy implications. One novel result is that imposing gear restrictions in the recreational fishery may have the exact opposite stock effects of imposing restrictions on the marine harvest.
