For the first time in history, humans are poised to harvest more fish and seafood from farms than they catch in the wild.
This milestone, expected within two years, would help keep the oceans from being overfished except for one issue: Those farmed fish eat wild fish.
Around 12% of the world’s wild whole-fish catch goes to feed fish and aquatic creatures like shrimp raised on farms, according to The Marine Ingredients Organization, a trade group for the international fish feed industry. Captive salmon and shrimp are fed fishmeal composed of smaller fish like sardines and anchovies, which themselves are being overfished in some parts of the world, damaging marine ecosystems and reducing an important food source for locals.
To solve the problem, teams of scientists and entrepreneurs are developing fish-free fish food from bacteria and insects, along with replacements to fish oil derived from algae and genetically modified canola. They are attracting funding from major investors like BP PLC and Temasek, Singapore’s national investment vehicle.
