This paper briefly reviews the importance of ontology within STS by situating this in wider intellectual shifts. Then it draws on ethnographic material on salmon farming to make four arguments within empirical ontology. First rehearses the argument that different salmon are done in different practices. Second, it again follows empirical-ontological conventions, and show that these are the effects of precarious and uncertain choreographies. Third, it touches on the textures of ordering in salmon-human enactments, showing that salmon may be done as slippery and elusive, and it argues that the textures of practices are crucial in defining the qualities of salmon for people. Finally, it touches briefly on the productivity of human-salmon relations, and argues that while farmed Atlantic salmon are indeed inextricably linked with people, they also escape from and are other to the human.
