Increased shark bite survivability revealed by two centuries of Australian records
Increased shark bite survivability revealed by two centuries of Australian records Jason P. Tucker, Isaac R. Santos, Brendan P. Kelaher, Marcel Green, Graeme F. Clark, Paul A. Butcher ABSTRACT: The perceived and real threat of shark bites have significant direct health and indirect economic impacts. Here we assess the changing odds of surviving an unprovoked

The role of aquaria in the advancement of elasmobranch reproductive biology
The role of aquaria in the advancement of elasmobranch reproductive biology Kevin A. Feldheim, Jennifer T. Wyffels, Kady Lyons ABSTRACT: Public aquaria showcase aquatic life while raising awareness and educating the public on biodiversity and the need for conservation. Recently, aquaria have followed in the footsteps of zoos by taking more directed approaches in species

Shark Fishing vs. Conservation: Analysis and Synthesis
Shark Fishing vs. Conservation: Analysis and Synthesis Ila France Porcher, Brian W. Darvell ABSTRACT: The expanding shark fin market has resulted in intensive global shark fishing and with 90% of teleost fish stocks over-exploited, sharks have become the most lucrative target. As predators, they have high ecological value, are sensitive to fishing pressure, and are
