Who owns the fish in the sea?
Any commercial fisherman used to be able to fish in U.S. oceans. Not anymore.
Today, the right to fish belongs to a number of private individuals who have traded, bought and sold these rights in unregulated markets. This system, called “catch shares,” favors large fishing fleets and has cut out thousands of smaller-scale fishermen. How did this happen?

Coral-killing seaweed has medicinal benefits, researchers say
California researchers have discovered that there may be a silver lining to an invasive and toxic seaweed that is killing some of Hawaii’s coral reefs: It seems the seaweed contains compounds that could treat human diseases.
"I think this finding is a nice illustration of how we need to look more deeply in our environment, because even nuisance pests, as it turns out, are not just pests," said William Gerwick, a researcher at UC San Diego and the Scripps Institution of Oceanography. “It’s a long road to go from this early-stage discovery to application in the clinic, but it’s the only road if we want new and more efficacious medicines.”
The study appears in today’s issue of the journal Chemistry & Biology.
The seaweed, a tiny photosynthetic organism known as a cyanobacterium, was identified in 2008 on coral reefs near the Pu’uhonua o Honaunau National Historical Park, off Hawaii’s Kona coast.
