Published online on 17. June 2015 Tonic immobility as an anaesthetic for elasmobranchs during surgical implantation procedures Steven T. Kessel, Nigel E. Hussey ABSTRACT: Tonic immobility is a widely used technique for the surgical implantation of acoustic tags in elasmobranchs (sharks, skates, and rays), yet it is still not broadly recognised as an acceptable procedure

Displaying uncertainty in the biological reference points of sharks

Published online on 28. July 2015 Displaying uncertainty in the biological reference points of sharks Matias Braccini, Elizabeth N. Brooks, Brent Wise, Rory McAuley ABSTRACT: Variability in life-history traits influences biological reference points (BRP). For data-poor species such as sharks, BRP have commonly been set at arbitrary values with little consideration of life-history variability. The
