The large fish indicator (LFI) is defined in broad terms as the proportion of total fish biomass of a defined suite of species sampled in a particular survey programme that exceeds a specified threshold length. It describes the proportion (by weight) of the fish community that is larger than some length threshold (40 cm for the North Sea). It provides a metric that can be related easily to a defined Ecological Quality Objective (EcoQO) based on a reference period when the fish community was considered to be exploited sustainably. | |||

Description:
The large fish indicator (LFI) is defined in broad terms as the proportion of total fish biomass of a defined suite of species sampled in a particular survey programme that exceeds a specified threshold length. It describes the proportion (by weight) of the fish community that is larger than some length threshold (40 cm for the North Sea). It provides a metric that can be related easily to a defined Ecological Quality Objective (EcoQO) based on a reference period when the fish community was considered to be exploited sustainably.
In the North Sea, the EcoQO is an LFI of ≥ 0.30.
