When it comes to commercial aquaculture, a lot of people have some legitimate concerns – fish farms can introduce antibiotics, anti-algal chemicals and concentrated fish waste into the ocean; escaped fish can upset the local ecological balance; and wild fish still need to be caught in large numbers, as a food source for some species of farmed fish. While there have been recent efforts to address the first two concerns, the fish-in-the-fish-food problem is now being taken on in two different research projects. These are aimed at replacing the fish content in fish feed with more sustainable ingredients.
