Feeding the future’s farmed salmon

One of the biggest critiques of farmed salmon is that their feed is made from raw materials that could be eaten by humans. Norwegian scientists are working to make fish food from trees and leftovers from the food industry.

The world’s first electrically powered fishing boat will be presented this August in Trondheim, Norway. But more time and development is needed before it can run completely without diesel.
