The Typical Length Indicator measures the size-structure of fish communities and it decreases under high fishing pressure. The indicator is low, compared to the 1980s, in the Greater North Sea and Celtic Seas Regions, but it has increased across large parts of the central Celtic Seas and the northern Bay of Biscay.

Spatially extensive decreases in planktivore feeding guild biomass lower in the food web were evident in the North Sea and Bay of Biscay sub-divisions. In contrast, biomass of the pisco-crustivore and piscivore feeding guilds higher in the food web increased in the Celtic Seas region and Bay of Biscay sub-division.
