Environmental Impact
Farming and fishing practices
Pollock and tilapia are farmed and fished in different ways. Pollock is a wild-caught fish that is mainly caught in Alaska, Russia, and Japan. It is usually caught with trawl nets, which can damage the ocean floor and catch other marine animals unintentionally.
