Keeping Wild Stocks Wild
When fish or shrimp are kept in pens or ponds that are connected to natural waterbodies, some can escape. This isn't as harmless as you might think. In some cases, escapees can impact wild populations by competing with them for food, habitat and spawning partners.
Most farmed species are distinctly different than their wild cousins. If escapees breed with their wild counterparts, the genetic makeup of their offspring may be less suited to surviving and thriving in the wild. In addition, fish are sometimes farmed in areas they are not native to. If they escape, they can establish themselves as invasive species and disrupt the harmony of the ecosystem.
What You Can Do
Salmon is one of the most commonly-eaten fish in the world, but did you know that most farmed salmon is on the "Avoid" list? Wild-caught salmon is generally a "Best Choice" or "Good Alternative," and there are a few similarly-sustainable farmed salmon options, so try to find out where your salmon comes from.
Our printable guides are broken down by region so you can find ocean-friendly seafood wherever you live or travel. Choose from the green "Best Choice" column. Otherwise, try a yellow "Good Alternative."
