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.
