A HEALTHIER OCEAN STARTS WITH SHARING.

A global overview of shark sanctuary regulations and their impact on shark fisheries (2017) CA Ward-Paige, eOceans - published in Marine Policy. Open access here.

In this paper I review and summarize the details of existing shark sanctuary regulations, to compare and contrast across all 11 countries, to understand how effective shark sanctuaries may be for protecting sharks. Shark sanctuaries may lower mortality, but understanding the impact of these sanctuaries as a preventative measure is extremely difficult - just because they have not traditionally had high shark catches doesn't mean that would always be the case. One thing is clear, however, that shark bycatch needs to be addressed across the board. I also make the case for immediately implementing "program evaluation" - such as through eOceans snapshot & monitoring studies - to establish baselines and to understand the impact of the shark sanctuaries on sharks and the entire community, including humans.

Global Population Trends and Human Use Patterns of Manta and Mobula Rays

Christine A. Ward-Paige, Brendal Davis, Boris Worm

eManta was a crowd-sourced survey of the world's expert scuba divers that was designed to evaluate the status of global manta ray populations. This study raised concern about Giant Manta and Devil Rays being wiped out by fisheries. Publication PDF

Global catches, exploitation rates, and rebuilding options for sharks

Worm B, Davis B, Kettemer L, Ward-Paige CA, Chapman D, Heithaus MR, Kessel ST, Gruber SH  (2013) . Marine Policy

Global shark fisheries reveals that at least 97 million sharks are killed each year and that mortality rates exceed their ability to reproduce, supporting evidence for declining populations.

Recovery potential and conservation options for elasmobranchs

Ward-Paige CA, Keith DM, Worm B, Lotze HK (2012) Journal of Fish Biology

Summary: 1) populations can recover - the earlier the better; 2) incidental fishing pressure can stall or prohibit recovery; and 3) management and conservation strategies must be multi-faceted in order to be successful.

Large-Scale Absence of Sharks on Reefs in the GreaterCaribbean: A Footprint of Human Pressures. 

Ward-Paige CA, Mora C, Lotze HK, Pattengill-Semmens C, McClenachan L, Arias-Castro E, Myers RA (2010) PLoS One

Relative lack of sharks on reefs reveals the extent of declines, unique condition of populations in Bahamas and Florida, and the potential for protective areas and management for maintaining shark populations.
