This Company Found A Way For Carbon Dioxide To Help Overfishing

By Tessa Love

As the world's hunger for seafood grows, the ocean's fish population is dwindling. More than 85 percent of the world's fisheries have been pushed to or beyond their biological limits due to overfishing – the process by which more fish are caught than the population can replace through natural reproduction – and several important commercial fish populations (such as Atlantic bluefin tuna) have declined to the point where their survival as a species is threatened.

One response to this crisis has been the growth of aquaculture production, or farming fish instead of catching them in the wild. The use of aquaculture production has more than doubled in the last 17 years, and while this can help preserve some wild species, there's still one problem: feeding farmed fish requires catching smaller fish from the ocean. In other words, the growth of aquaculture has only worked to exacerbate the problem. 

In an effort to find a way to feed farmed fish more efficiently, one startup has turned to an unlikely source: carbon dioxide.
