ANT and politics:working in and on the world

Actor-network theory (ANT) comes from Science, Technology and Society (STS), a discipline that is distinctive because it thinks theoretically through a rich tradition of qualitative case studies. This means that while it is possible to define ANT in a series of abstract bullet points, attempts to do so miss most of the point. Words aren’t enough. You need to practise it. For this reason this paper draws on an ANT-inflected ethnography of farming. For related reasons we also work dialogically, because in ANT theory doesn’t pre-exist, waiting to be applied. Instead it is created, recreated, explored and tinkered with in particular research practices. Hence we argue that ANT is best understood as a sensibility to features of the world that aren’t quite those of standard social science: to the heterogeneous materialities, relationalities and uncertainties of the practices that compose the world. And, as we have also tried to show, this is a sensibility that has political consequences. ANT works on the assumption that other worlds are possible, then it tries to articulate them. The hope is that if we can craft appropriate tools for articulation it will be possible to know and make space for different and better social arrangements

Heart rate and swimming activity as stress indicators for Atlantic salmon (Salmo salar)

We investigated the relationship between telemetry measurements of heart rate and swimming activity and the physiological status in farmed Atlantic salmon (Salmo salar) to assess the potential to use telemetry measurements as proxies for stress. Sensor tags measuring heart rate and swimming activity were surgically implanted into the peritoneal cavity of Atlantic salmon individuals kept in tanks. Four tanks were stocked with three tagged fish and four untagged cohabitants, while two additional tanks containing 16 untagged fish were used as reference groups. Following surgery, tagged fish were kept undisturbed for 14 days as acclimation period. All fish were then subjected to physical stress by reducing the tank water level in 4 consecutive rounds, after which they were left undisturbed for another ten days before the experiment ended. Plasma cortisol, glucose, lactate and osmolality were measured to assess stress levels from fish in the reference groups before and after being subjected to stressing and from all fish at the end of the experiment. Both heart rate and swimming activity rose after the stress treatment, remaining elevated for 24.5 and 16.2 Hrs respectively. Glucose, plasma cortisol, lactate and osmolality levels were significantly greater when measured immediately after stress. Results from the experiment indicate that heart rate and swimming activity can be used as proxies for fish stress, thus opening the possibility for on-line stress monitoring in full scale production.publishedVersio
