CAPTURE, PHYSICAL AND CHEMICAL RESTRAINT
During any capture procedure, the aim is to minimise procedure duration and reduce its potential for negative effects (Gales et al. 2009). Recent reviews have described manual restraint techniques used in pinnipeds (Barnes et al.
2008; Lynch and Bodley 2014; Haulena 2014). In some circumstances, pinnipeds cannot be safely handled without chemical restraint. The drug delivery system should minimise disturbance and stress to the animal, while maximising efficiency and consistency of drug delivery. Chemical restraint by remote drug delivery (darting) may be the most appropriate method and darting techniques for chemical restraint of Southern Hemisphere pinnipeds have been reviewed by Baylis et al. (2015). Tiletamine- zolazepam is the agent most frequently used in free- ranging Southern Hemisphere otariid seals and southern elephant seals, and has been found to be a reliable anaesthetic agent in free-ranging leopard seals and Weddell seals (Carlini et al. 2009; Vogelnest et al. 2010; Tryland et al. 2012; Bornemann et al. 2013; McKenzie et al. 2013).Pinniped capture and physical and chemical restraint techniques are reviewed in Chapter 9.
