Rationale: This indicator is based on the vector of biomasses of the demersal species caught during the ecosystem survey in the demersal trawl. Following the widely accepted paradigm that diverse communities are more stable through time, and therefore more able to sustain either human or climate driven change, our approach can classify these sub-areas along a “resilience-to-change” gradient.
