Se acaba de publicar en la revista Fisheries Management and Ecology nuestro artículo sobre el uso del conocimiento de los pescadores y de herramientas de gestión baratas, aplicado a la pesquería recreativa de calamares y sepias en la Ría de Vigo Este artículo forma parte de los resultados del Proyecto RECREGES. El título original:
A new methodology based in the use of fishers’ knowledge and cost-effective tools to obtain information about marine recreational fisheries (MRF) is presented. The squid and cuttlefish fishery of the Ría of Vigo (NW Spain) was selected because it is managed in a data-poor environment. In-depth interviews (57) were conducted with fishers, collecting ecological and socio-economic information. A cartography of fishing grounds based on their knowledge was obtained, while the intensity of effort and catches was mapped by the monitoring of two vessels with low-cost GPS data loggers. The 102 shore anglers and 248 recreational boats catch 8 t/year of European squid Loligo vulgaris and 11 t/year of common cuttlefish Sepia officinalis (11% of total catches on these species in the area). Shore anglers fish from 11 ports, while boat fishers use 14 fishing grounds (covering 30 km2). Most of the catches (86%) are landed by boats, and their CPUE is higher in the outer part of the Ría of Vigo. The use of fishers’ knowledge and cost-effective monitoring is encouraged to obtain information for the management of MRF. Given the economic contribution of MRF (260,000 €/year in direct expenses), this activity should be considered in the regulations.

El título y el resumen del trabajo:
The use of the traditional ecological knowledge of fishermen, cost-effective tools and participatory models in artisanal fisheries: Towards the co-management of common octopus in Galicia (NW Spain)
- • We have monitored a Spanish octopus fishery by using GPS-loggers and logbooks.
- • We have also used the knowledge of octopus fishermen to map their fishing grounds.
- • Annually, 700 vessels use traps to catch 2000 t of octopus that are sold for 13 M €.
- • The 174 km2 of fishing grounds identified were the most fished and valuable areas.
- • Creation of a long term co-management plan is recommended to ensure sustainability.
The fishery of octopus Octopus vulgaris in Galicia (NW Spain) is a paradigmatic example of top–down management that generates conflicts between fishermen and policy makers. In the absence of scientific information to support the management of this data poor artisanal fishery, the traditional ecological knowledge (TEK) of fishermen was tested to map the distribution of fishing grounds and GPS data-loggers and log-books in order to estimate the intensity of effort and CPUE. Furthermore, a description of the social, technical and ecological features of the fishery was obtained to be used in conjunction with the results of questionnaires answered by experts, to improve the current management and to ensure the long-term sustainability of one of the most traditional and economically relevant fisheries in Galicia. Approximately, 700 vessels use traps in Galician coastal waters to catch 2000 t of octopus annually, with a market value of 13 M Є. Octopus vessels also use gillnets, hooks and lines and shellfish gathering to target common spider crab Maja brachydactyla, goose barnacle Pollicipes pollicipes and other species. The fishermen operating in the study area of the Ría of Arousa identified 174 km2 of octopus fishing grounds, mainly distributed in the mid and outer parts of the study area. The fishing effort was exerted on the same rocky reefs, also the most valuable fishing grounds in terms of CPUE. The use of new techniques and tools based on participatory models is encouraged to obtain cost-effective information of this fishery and in general of other fisheries in data poor environments. Likewise, the creation of a long-term co-management plan is recommended to ensure the sustainability of stocks and the profitability of this artisanal fleet.
En esta Caja de Herramientas del proyecto GAP2 se han incluido herramientas útiles y algunos consejos para ayudar a diseñar un proyecto de investigación colaborativo. La caja de herramientas se ha construido para ser lo más accesible posible y puede ser utilizada por cualquier persona, desde científicos a responsables políticos o pescadores interesados en saber más acerca de los procesos participativos.
