The dire state of global fish stocks is pretty well known by now - with costs of poor management of fish stocks running to $50 billion a year. Yet what's the alternative? Sea-based fish farming carries dire environmental risks, and while a few brave souls are experimenting with urban aquaculture, a solution to feeding the world's appetite for seafood without depleting the world's seas still seems a long way off. The Baltimore Sun brings us news from the UMBI Center of Marine Biotechnology in Maryland, who have developed a system for supplying sustainable seafood from on-land farms.

The center is also trying to develop a new fish food based on algae and plants - rather than ground up fish. …
