#Sharks2018 #SharkRayMPA @crigby4 : Coral reef resident species of sharks benefit from reef MPAs, as do migratory species that spend lots of time in those protected areas- a species need not spend all its time in an MPA to benefit from MPA protection.

#Sharks2018 #SharkRayMPA @crigby4 : There is still shark mortality in Shark Sanctuaries- bycatch from fisheries that aren’t illegal. Some Sanctuaries are implementing gear restrictions to reduce shark bycatch.

#Sharks2018 #SharkRayMPA @crigby4 : Many MPAs don’t have clearly defined goals or conservation targets, making it difficult to determine if they’re succeeding.

#Sharks2018 #SharkRayMPA @crigby4 : Shark-focused MPAs and Shark Sanctuaries cover about 6% of the ocean. Considered simple and less resource intensive to enforce, but there are concerns about “paper parks” that prevent more effective measures. Not much scientific study yet!

#IDEAS18 #SharkRayMPA @Drsharkbrain : Bigger shark species typically have larger home ranges/activity spaces, which means you need to protect a larger area to help them

#IDEAS18 #SharkRayMPA @Drsharkbrain : Ranges of some shark species have very little overlap with protected area boundaries. So they’re not protected well.

#IDEAS18 #SharkRayMPA @Drsharkbrain : Marine protected areas are often discussed as a shark conservation tool. But do they work? (It depends!)
