El terrorismo ha condicionado la vida política y social del País Vasco durante más de cuatro décadas. ETA fue la responsable del 92 por 100 de los asesinatos cometidos por todas las organizaciones que actuaron en este territorio. Fue también la única que contó con un proyecto político y un entorno que apoyó sus acciones. Su actuación marcó absolutamente el desarrollo de la vida democrática, extendiendo el miedo y coartando la libertad de miles de vascos. Tras el final del terrorismo se ha producido una eclosión de investigaciones que analizan su historia y las consecuencias que ha tenido en la sociedad vasca.

The present viewpoint summarizes the major threats to the sustainability of marine food resources from an applied ecological and fishery approach. Threats include unsustainable activities related to fisheries, aquaculture, urban and tourism development, marine traffic, introduced and spread of non-native species, other human industrial actions, as well as climate change, invasive alien species, and inadequate policies and legislation. This contribution still aims to identify main key elements concerned in the sustainable use of these resources; six groups are identified: (1) identification of main exploited commercial species, differentiation from other similar resources, and normalization of their common names; (2) ecosystem-based management of coastal ocean waters; (3) biodiversity, taxonomic biogeography and oceanographic forces; (4) responsible fish consumption; (5) ''Mediterranean diet"; (6) fisheries biology studies, mainly with an ecosystem approach. A comparison between most-consumed native fishing products in Spanish Mediterranean and Canary Islands shows high similarity in seafood, putting in evidence the broad presence of the "Mediterranean diet" in both regions. This paper also aims to be a baseline to support and identify ongoing/further measures for conservation of associate biodiversity and main exploited commercial species. Some remarks on fisheries biology studies, as a useful tool for assessment, management and conservation of marine food resources are made; these are related to: regulations of fishing gear and fishing activity; assessments of their impact as well as of the commercial fish stocks potentiality; improvement of the statistical control of fish landings; marine protected areas; application of the ecosystem approach; and awareness of responsible fish consumption. ; 5 ; 1
