Desert aquaculture in Arizona and the Negev in Israel is booming, and it could get another shot in the arm from groundbreaking work on natural alternatives to antibiotics.
Sea cages and coastal farms generate the bulk of aquaculture’s yield, and these operations are under attack because of their adverse effect on wild fisheries. Disease and parasites from the farms breech the farms’ barriers and infect native stocks, and 10 million tons of the wild fish harvested each year become fishmeal for fish-farm operations.
