The study used visual censuses and the analysis of stable isotopes to determine the abundance and trophic niche of carnivorous fish in marine reserves and areas open to fishing.

Recerca Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact —mainly fishing—, but, are they enough to recover the functioning of these systems? A study published in the ICES Journal of Marine Science , led by researchers from the Biodiversity Research Institute ( IRBio ) of the University of Barcelona, in collaboration with researchers from the Group of Ecosystem Oceanography (GRECO) of the Oceanographic Center of the Balearic Islands, highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.

"This study shows that with only the small-scale marine reserves, it is not enough to conserve the functionality of marine ecosystems.
