The escape of cultured fish from a marine aquaculture facility is a type of biological invasion that may lead to a variety of potential ecological and economic effects on native fish. This paper develops a general invasive species impact model to capture explicitly both the ecological and...

This paper explores the ecological and economic impacts of interactions between escaped farmed and wild Atlantic salmon (Salmo salar, Salmonidae) over generations. An age- and stage-structured bioeconomic model is developed. The biological part of the model includes age-specific life history...

A biomass model of a wild salmon (Salmo salar) river recreationalfishery is formulated, and the ways in which economic and biological conditionsinfluence harvesting, stock size, profitability, and the benefit of the anglers arestudied. The demand for recreational angling is met by fishing...
