Keeping a world-class public aquarium facility sustainable involves numerous aspects beyond making sure the over 20,000 animals inside the aquarium are receiving sustainably harvested food that totals 100,000 pounds yearly. Water handling, power consumption, and waste management are all part of the sustainable approach to running aquariums. But, this aquarium thinks outside the tank too, and is playing a leadership role to ensure all of San Francisco consumes fish sustainably by following the Seafood Watch Program.
