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.

  • A handful of transnational corporations control large (>50%) shares of supply chains in agriculture, fishing, logging, and mining.

    “A handful of transnational corporations control large (>50%) shares of supply chains in agriculture, fishing, logging, and mining ( 71 , 72 )”

    The Introduction describes transnational seafood corporations operating across supply chains, and the Results find that 13 corporations control substantial shares of marine catch and valuable fish stocks. The paper does not establish a >50% share of supply chains in fishing, agriculture, logging, or mining; its reported seafood shares are 11–16% of global marine catch and 19–40% of the largest and most valuable stocks. (LLM, conf=0.89)

  • Funds channeled through tax havens support most illegal, unreported, and unregulated fishing, creating governance challenges.

    “whereas funds channeled through tax havens support most illegal, unreported, and unregulated fishing ( 71 , 73 ), creating governance challenges.”

    From Pervasive human-driven decline of life on Earth points to the need for transformative change (2019) · cites this paper as [71]

    The Discussion describes challenges in fisheries governance, and the Results mention efforts to reduce illegal, unreported, and unregulated fishing. Neither section addresses funds channeled through tax havens or says they support most such fishing (searched: tax havens, financing, IUU fishing). (LLM, conf=0.76)

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.
