Marine Trophic Index [BIP]

Marine Trophic Index [BIP]

Indicator description

Fish currently supply the greatest percentage of the world’s protein consumed by humans. However, most of the world’s fisheries are being fished at levels above their maximum sustainable yield and many regions are severely overfished. The Marine Trophic Index measures the mean trophic level for all Large Marine Ecosystems and hence indicates the extent of ‘fishing down the food webs’. This provides a measure of whether fish stocks, especially of large bodied fish, are being overexploited and fisheries are being sustainably managed.

Mapping with CITES Strategic Vision: 2008-2020

Objective 1.4

The Appendices correctly reflect the conservation needs of species.

Mapping with SPMS 2015-2023

CMS Target 5

Governments, key sectors and stakeholders at all levels have taken steps to achieve or have implemented plans for sustainable production and consumption, keeping the impacts of use of natural resources, including habitats, on migratory species well within safe ecological limits to promote the favourable conservation status of migratory species and maintain the quality, integrity, resilience, and ecological connectivity of their habitats and migration routes

CMS Target 6

Fisheries and hunting have no significant direct or indirect adverse impacts on migratory species, their habitats or their migration routes, and impacts of fisheries and hunting are within safe ecological limits.

Mapping with Sustainable Development Goals

SDG Target 2.4

By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil quality

SDG Target 12.2

By 2030, achieve the sustainable management and efficient use of natural resources

SDG Target 12.8

By 2030, ensure that people everywhere have the relevant information and awareness for sustainable development and lifestyles in harmony with nature

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
