As the climate gradually grows warmer and cattle farming becomes less and less attractive a solution for world food production, scientists and innovators are working to develop suitable alternatives that can feed the world without wasting too many of its resources. While modern seafood farming -- or "aquaculture" -- is a step in the right direction, its current methods are problematic in their own right. If aquaculture's problems can be solved, though, it stands to revolutionize the way we feed the world. In search of this holy grail are some of Israel's brightest minds: aquaculture technology companies and innovators developing new, better ways to yield sustenance from the sea. Biologist Roni Hochman Sussman is the director of AquaculTech, a joint initiative of the Ministry of Economy and Industry Ministry, the Agriculture Ministry, the Israel Innovation Authority and the Israel Innovation Institute.
