Sustainable Seafood Consumption

Figuring out how to be an environmentally-conscious consumer is important, but let's not kid ourselves --- it's also complicated. Especially when it comes to seafood. Some fish species are best to buy farm-raised, others are recommended wild-caught only, and some just shouldn't be consumed at all because of the state of the fisheries.

Salmon farming is a great example of this problem. So we don't want to over fish the wild populations of salmon, so why not just farm them? Well, farming can actually harm the wild populations in some cases. Crowding together fish in such a small area causes diseases to become epidemics, where as in the wild the diseases would be kept at low levels by predation on the sick ones. Huge groups of farmed salmon infected with sea lice cause wild salmon to have a higher likelihood of catching the parasite, with greater amounts of sea lice being transported to waters around the farmed salmons' cages. So not only does the farming hurt the local environment because it produces so much waste contamination in the water from the huge masses of fish that would not normally be there, but it also hurts the wild salmon by infecting them with parasites.

Poor baby salmon. :(

Since we all want our descendants to be able to enjoy these species once we are long gone, but realistically, there is no way for us to research all of this intricate information on all species of fish we purchase at the grocery store or at a restaurant, I'd like to encourage the world to take advantage of the following tool. The Monterey Bay Aquarium has created a sustainable seafood guide to help consumers purchase wisely. Through either an online guide, printable pocket guide for your wallet, or mobile guide for your smart phone, the vast majority of the work is done for us. I can just whip out my phone if I am thinking about purchasing some fish at the grocery store, and the guide will give me a good idea as to what my best options are. Even some grocers that tout themselves as more environmentally conscious, like Whole Foods, still offer seafood options labeled as "Avoid" by the Seafood Watch Guide -- so as consumers, we have to be conscious of this all the time. Fish are yummy, so we might as well keep them around as long as possible and try to avoid population collapse.
