Large Reef Fish [BIP]

Large Reef Fish [BIP]

Indicator description

The cumulative take and impacts of commercial, recreational and subsistence fisheries on coral and rocky reefs are presently unknown, precluding ecologically sustainable outcomes through the long term. At large scales, fisheries impacts are currently estimated from what has been taken from the sea (i.e. from fisheries catch data), rather than what remains in marine ecosystems. The Large Reef Fish indicator is essentially a variant of the Large Fish Indicator (LFI) used for The Marine Strategy Framework Directive (MSFD) in Europe but represents an in situ biomass density (kg/ha) based on underwater censuses of fishes from rocky and coral reefs, rather than a proportion of biomass from fisheries catches or trawls. It is a direct estimate of fishable biomass on shallow reefs. It can be used to track biodiversity responses to fishing, effectiveness of marine protected areas (MPAs) and is also relevant to understanding climate impacts on fisheries opportunities in vulnerable reef habitats such as coral reefs or kelp forests.

Mapping with Sustainable Development Goals

SDG Target 14.2

By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans

SDG Target 14.4

By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics
