Free captive fish

Abstract: As fish stocks dwindle in our oceans, the obvious solution is to turn to farming. But, to be profitable, fish farms need to keep large numbers of fish in close proximity — and this results in a depletion of food and oxygen from the water. Some fish farms try to solve this problem by ‘walling off’ a region of natural water with a net, and Daedalus now wants to take this idea even further. He suggests releasing a shoal of young adult fish within a large net into the open ocean, and allowing this ‘fish corral’ to drift through the open water.
