Abstract
Background. Fishing is a primary activity of great importance in the Canaries and has traditionally played an important role in reducing poverty, in job creation, strengthening food security and sovereignty, and increasing the value of its products. This study is needed to analyze fishing contribution in a region strongly based on tourism. Aims were: to update the inventory of fishing techniques, to detail the biodiversity involved, and for the first time to analyze the contribution of the landings. We also identify threats to the activity and draft a plan with strategic actions for its sustainability. Materials and methods. Data on the fisheries and the 2007–2018 series of landings were taken from the regional government website. Once the database was refined, data were analyzed in main four environmental resource categories: shellfish (SHS), demersal fish (DMF), coastal pelagic fish (CPF), and oceanic pelagic fish (OPF). To analyze the economic contribution of the fisheries, first-sale reference prices were compiled from fisheries entities. To estimate the contribution of this sector to the regional GDP, its economic value was compared with the mean value of GDP for 2014–2018 GDP. Results. The versatility is the main characteristic of the fleet, which was stabilized around 600 vessels within 2016–2018. Fishing techniques vary enormously, and eight categories of fishing gear were identified. Total landings ranged between 5560 t in 2007 and 15466 t in 2016, with a mean value of 11 254 t · y–1. SHS reached a mean value of 111 t, representing only 1%, DMF 1683 t (16%), CPF 1926 t (17%), and OPF 7533 t (65%). Biodiversity targeted by these fisheries throughout the 2007–2018 period involved about 200 species. As a primary sector, the Canary Islands’ fishing activity made a mean value of the economic contribution of €73.19 million per year at first-sale in 2007–2018, contributing 0.19% of the regional GDP overall during 2014–2018. When the fishing activity is considered together with other local socio-economic sectors in the value-added chain of seafood, it contributes acceptably to the regional economy. Conclusion. Overexploitation of fish stocks is the greatest problem to solve, followed by poaching and the growth of intense recreational fishing. Ad-hoc strategic and structured actions for the sustainable development of the fishing activity are proposed.
Highlights
The Canary Islands are an overseas Spanish territory and an outermost European piece of land situated in the eastern-central Atlantic Ocean
With more than 2.2 million inhabitants, the Canary economy is mainly based on the tourism industry, receiving in recent years about 16 million visitors and tourists per year
Comparing the different environmental resource species: SHS landings reached a mean value of about 111 t, demersal fish (DMF) landed attained a mean value of about 1637 t with 16%, coastal pelagic fish (CPF) reached about 1973 t with 18%, and lastly, oceanic pelagic fish (OPF) reached about 7533 t with 65% (Table 1)
Summary
The Canary Islands (eight inhabited islands covering a total of 7500 km2) are an overseas Spanish territory and an outermost European piece of land situated in the eastern-central Atlantic Ocean. The age of the islands varies from east to west between 21 and 0.7 million years Their volcanic characteristics are seen in their lack The geomorphological, geographical, and of wide insular shelves, often with a mean bottom depth oceanographic particularities of the Canary archipelago of 200 m near the coast. This archipelago has nearly 1600 may explain the great diversity in the biogeographic km of coastline and is washed by the oligotrophic ocean patterns of the biota inhabiting this area. Ad-hoc strategic and structured actions for the sustainable development of the fishing activity are proposed
