do not seem to have many non-monetary concerns relating to tuna. This contrasts the

fattening ranches, and the fact that less tuna is landed locally – a point I return to when

Tuna as stock: scientists and regulators

In the early twentieth century the move to limit fisheries for the common good had begun to

take form as part of the application of science, policy and regulation to manage ecology as

resources (Epstein in Barclay 2016, p. 67). The focus of fishery management and science

based on the ecosystem (limnology), was largely replaced by the simpler approach of

studying target species and analysing fishing impact in terms of MSY (Larkin in Barclay

2016, p. 68). MSY came to underpin fishery management in most governments and

intergovernmental organisations (Barclay 2016, p. 69) like ICCAT. It is the basis of a TAC
