Industrial fisheries are not unique factor in overexploiting natural resources in the
Costa Brava, other important species such as selfish, sea-baits, sea-urchins, actinias, or
littoral fishes today suffer overexploitation due to direct collection (lucrative or not)
or sports fishing; it is almost impossible to carry out a compilation of such kind of
catches. These kinds of highly seasonal exploitation also have importance in modifying habitats and in alter coastal ecosystems. Studies conducted in the Marine Reserve
