One of the major contributions of the current EU Data Collection Framework (DCF) was the shift from a stock-based approach towards a fishery-based approach. The aim of this change was serving the new demands of the fisheries management in order to include the ecosystem approach in the assessments. Since 2009, the MS national fisheries sampling programs had to adopt the concurrent sampling strategy, which implies that length structure of all species landed must be obtained during the sampling operation. The Northern Spanish coastal small scale fleet represents a major challenge for sampling due to the multi-species and multi-gear character and the complexity of the fleets’ dynamics. Particularly, the small-scale gillnets called “beta” represents one the more complex Spanish métiers in terms of catches (1850 t in 2014), effort (23341 trips), geographical distribution (Division VIIIc and IXa), and the number of exploited species (38 species within 90% of total landings). Some of the ...
