A Review of Bioeconomic Modelling of Habitat-Fisheries Interactions

الملخص EN

This paper reviews the bioeconomic literature on habitat-fisheries connections.

Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model.

We attempt to clarify the nature of linkages between the function of habitats and the economic activities they support.

More specifically, we identify theoretically the ways that habitat may enter the standard Gordon-Schaefer model, and nest these interactions in the general model.

Habitat influences are defined as either biophysical or bioeconomic.

Biophysical effects relate to the functional role of habitat in the growth of the fish stock and may be either essential or facultative to the species.

Bioeconomic interactions relate to the effect of habitat on fisheries and can be shown through either the harvest function or the profit function.

We review how habitat loss can affect stock, effort, and harvest under open access and maximum economic yield managed fisheries.
