Limitations and Demarcations of Transgenic Salmon Market : The Political Work of Scientific Experts

The american Food and Drug Administration is about to give its opinion about the commercialization of AquAdvantage Salmon, a transgenic salmon for human consumption. The creation, in progress, of this market raises the question of operations of scientific experts necessary to define a new bio-legal entity and to ensure its viability in the marketplace. We experience here the conceptual framework designed by Javier Lezaun to analyze the factory of a new object of governance, extending however its use to the manufacture of a market. This article explores the acts of delimitation and demarcation of the entity "transgenic salmon" necessary for its entry into the American legal architecture, but also the demarcation operations resulting from a growing tension between promoters of this project, scientific experts and civil society, all requiered for its potential commercialization in the US markets. This case permits to understand a part of science-policy dynamics works.
