Keystone dialogues

As in other business areas, a few companies in the world control almost the overall seafood market.
These key companies, responsible for most of the seafood production, are committing to move further to sustainability with science support.

If they do, others might follow.

This is an interesting initiative since apart from the scientific background it is based in "dialogues", "communication" and "connecting" different parts of the issue.
The seafood production is a business above all the resources or environmental constrains and if we want to improve sustainable measures, it is not enough to use only science based policies or consumers' advice.
We need to connect the parts.

The word “keystone actor” is an analogy with the “keystone species” concept in ecology, developed by Professor Robert T. Paine. A scientific paper published in 2015 by Österblom, Jouffray, Folke et al. illustrates that the largest companies in a given industry can operate similarly to keystone species in ecological communities, meaning that they can have a disproportionate effect on the structure and function of the system in which they operate.
The keystone actors of global seafood control 19-40% of some of the largest and most valuable stocks and 11-16 % of the global marine catch. Keystone actors can be defined by the following characteristics:

• they dominate global production revenues and volumes within a particular sector
• control globally relevant segments of production
• connect ecosystems globally through subsidiaries
• influence global governance processes and institutions
