Estimating Linkages between Redfish and Cold Water Coral on the Norwegian Coast

The rise and fall of the Irish orange roughy fishery: An economic analysis

“…As bottom trawling expands its reach into steadily deeper waters, CWC reefs are getting increasingly damaged. Foley et al [19] applied a production function approach to reveal that a decline in CWC habitat of between 30% and 50% could explain a drop in the harvest of Norwegian redfish of between 11% and 29%. Hence despite fisheries increasingly being managed, the commons nature of fish habitats may be resulting in the classical tragedy.…”

“…By damaging cold water coral, destructive fishing practices thus impose user costs 1 on the fishermen themselves but also other stakeholders. Glenn et al [18] report that the Irish public show strong preferences for a ban on trawling in order to conserve cold water corals in the Atlantic and Foley et al [19] suggest that fishing practices that damage cold water coral may reduce the yield of another deep sea fish species, redfish. Armstrong and van den Hove [20] also suggest that deep sea trawling can damage cold water coral and impose external effects on coastal fishermen.…”

A Review of Bioeconomic Modelling of Habitat-Fisheries Interactions

“…It is also possible that both carrying capacity and the intrinsic growth rate are increasing functions of habitat in the facultative model as shown by Foley et al [20]. For {a, b, f , g} > 0, the growth function becomes…”

“…Foley et al [20] consider the impact of reduced cold-water coral habitat on the growth function of redfish. They test for a facultative and an essential relationship.…”

“…They found that in each case the results were similar. Barbier and Strand [16] and Foley et al [20] also present habitat as essential for the growth of the fish stock. The effect of an essential habitat on the growth function is similar to Case (3) and results in an outward shift of the growth curve (see Figure 1).…”
