Transnational Corporations as ‘Keystone Actors’ in Marine Ecosystems

Open access

Abstract

Keystone species have a disproportionate influence on the structure and function of ecosystems. Here we analyze whether a keystone-like pattern can be observed in the relationship between transnational corporations and marine ecosystems globally. We show how thirteen corporations control 11-16% of the global marine catch (9-13 million tons) and 19-40% of the largest and most valuable stocks, including species that play important roles in their respective ecosystem. They dominate all segments of seafood production, operate through an extensive global network of subsidiaries and are profoundly involved in fisheries and aquaculture decision-making. Based on our findings, we define these companies as keystone actors of the Anthropocene. The phenomenon of keystone actors represents an increasingly important feature of the human-dominated world. Sustainable leadership by keystone actors could result in cascading effects throughout the entire seafood industry and enable a critical transition towards improved management of marine living resources and ecosystems.

Figures

Fig 1 Revenues of the 160 largest seafood companies. Revenues of the 160 largest seafood companies in 2012 [12, 13] (circles, data show as mean ± s.e.m.) with the top ten per cent indicated by the dashed line, and corresponding revenues of the top 16 seafood companies in 2007 [10] (triangles). Maruha Group (ranked 1st in 2007) and Nichiro Corporation (ranked 5th in 2007) merged in 2008 to form Maruha Nichiro (ranked 1st in 2012). Pacific Andes (ranked 15th in 2007) acquired China Fishery Group Limited (ranked 23rd in 2007) and is currently the 9th largest seafood company in the world.

Fig 3 Regional fisheries of global relevance. Globally important wild fish stocks by volumes (grey circles with blue wedges), aquaculture production volumes (orange wedges), and global fishmeal, fish oil and aqua feeds (salmon, shrimp and whitefish feeds combined) volumes (purple wedges), and their corresponding economic value (green circles). The proportion of each stock controlled by the keystone actors is indicated by the size of the wedge. The number of companies active in each stock is shown within brackets.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
