For all the Lost Sharks

It was found that with traditional fish stocks 90% overfished, sharks (along with tuna) have become the most lucrative prey for fisheries due to the value of their fins. So, with fishing scarcely profitable any more, fishing fleets around the world have joined in the hunt for them. The meat is pushed onto consumers using other names, so it is largely the shark fin trade that drives the so-called market for shark meat.

As a result, those species of sharks and rays accessible to fishing fleets are approaching extinction.

White sharks complicate population recovery for sea otters

Complex interactions and conflicts between protected populations may challenge the recovery of whole ecosystems. Several factors indicate that white sharks may be currently limiting the recovery of California sea otters.

Protected white sharks (Carcharodon carcharias) and pinnipeds have an established predator–prey relationship along the California coast.

Shipping poses substantial threat to whale sharks

As whale sharks assemble in coastal regions to spend substantial time in surface waters, experts theorised collisions with ships could be causing substantial whale shark deaths. Previously, there was no way of monitoring this threat.

Scientists from 50 international research institutions and universities tracked both whale shark and ship movements across the globe to pinpoint areas of risk and potential collisions. Satellite-tracked data from nearly 350 whale sharks was submitted to the Global Shark Movement Project, conducted by MBA researchers.
