Projections show that sea fish may disappear as food by the middle of the century. Protected zones may help keep fish populations from disappearing. Blogged by "The Red Mullet", story originally from the BBC.

Interesting defense from salmon industry regarding farmed salmon
Amazing the kind of angry firestorm a blog entry on "reasons not to eat some farmed salmon" can cause. The entry itself is fine but the knives and daggers come out in the comments. Seems a bit extreme until you realize that the daggers seem to be coming from the president of the Salmon of the Americas trade group (just google the angry guy's name).
Seafood Watch: Eating Sustainably from the Ocean
Over one-third of the seafood sold are now farm-raised, in order to keep up with this demand. Overfishing has nearly wiped out many once-common species like cod, bluefin tuna and rockfish. Depending on the fishing method, other wildlife can be unintentionally caught as part of the bycatch. For every pound of shrimp caught in trawl nets, up to TEN pounds of other sealife can be killed. So how can we choose wisely, with so many issues to consider?
