How many people are aware that we've removed almost 90% of predatory fish from the ocean? Some turn their nose to the idea of "farm raised" fish but it's turning out to be the best option right now. Why do you think they limit the fishing so much as what's seen on the show Deadliest Catch, we've depleted our resources. If we haven't depleted them yet, we're getting their fast by overfishing, illegal and unregulated fishing, habitat damage, and bycatch.
Fish is my favorite protein to work with and watching the decline of this species is disheartening to say the least. Fisheries can be dependable but there are far too many fisheries that are not managed properly. This is why you hear of Tilapia fisheries in particular, where the fish are somewhat hazardous for human consumption.
I would like to urge anyone that reads this to research their food options much more before buying. It can be a little annoying to try and find the information that's needed but it will be well worth it. Not only will this research lead to a safer product to feed your family but a much tastier one at that.
