A multimethod approach to assess marine recreational fishing activity in a Mediterranean area: A case study of the Balagne region (Corsica, France)

Objective

Recreational fishing is a growing concern in the management of fishery resources given its economic impact, the number of people involved, and the magnitude of catches. Despite its significant impact on marine resources and ecosystems, recreational fishing has received less attention in research than commercial fishing.

Methods

This study focuses on marine recreational fishing in Balagne (Corsica, France, northwestern Mediterranean). It presents, for the first time in this region, valuable data on the population size of recreational fishers; their sociological profiles; fishing habits; and, specifically, catch data related to boat fishing.

Result

Through an extensive telephone survey involving 387 households, we estimated that recreational fishers constitutes 10.2% of the population, with the majority being men (84.84%). The average age varies significantly based on the type of fishing practiced: 38.4 years for spearfishing, 50.2 years for shore fishing, and 56.4 years for boat fishing. Additionally, the study found that shore fishers declare practicing no-kill fishing more frequently than do boat fishers (90.00% and 56.67%, respectively). Photographic protocol, fishing logbooks, and boarding provided data on catch composition and fishing characteristics. In the case of boat fishers, catches per unit of effort, estimated from boarding data, were found to be 1.03 ± 1.51 individuals/h/fisher and 222.32 ± 318.94 g/h/fisher. Despite the great diversity among the species caught (49 species), Comber Serranus cabrilla, Blackspot Seabream Pagellus bogaraveo, Black Seabream Spondyliosoma cantharus, and Painted Comber Serranus scriba are overly represented in number among the species of marine fish caught by boat fishers and Common Dentex Dentex dentex, Greater Amberjack Seriola dumerili, Dolphinfish Coryphaena hippurus, and Bluefin Tuna Thunnus thynnus are overly represented in weight. Among all individuals caught and measured, about one out of two individuals (48.97% of catches) does not reach the legal size.

Conclusion

This study reveals the need to establish monitoring, surveillance, and control programs to ensure the sustainability of fish stocks and fisheries, including recreational fisheries.
