The aquarium uses natural processes wherever possible. Natural systems cleanse nitrate wastes, so that the water can be recycled through miles of pipes. Saltwater, piped underground from the Pacific four miles away, is passed through sand and carbon filters before it enters the tanks. The pH value and chemical content in each tank is adjusted to replicate the environments in which the animals have evolved. Solar cells built into the canopy that surrounds the roof play a large part in the heating system. Throughout all the exhibits are frequent references to the necessity for conserving all natural environments and the whole marine ecosystem in particular. “There is a strong conservation message,” says Andrews, “but you don’t get hit with a two-by-four.” Some of the graphics are designed to plant the seeds, and the staff, interns, and docents provide reinforcement. The actual conservation programs will be done mostly in partnership with other organizations. The Academy has signed a contract with the U.S. Fish and Wildlife Service to help save the endangered tidewater goby. This tiny fish is found in the brackish estuaries of northern California. Its life cycle lasts only 12 months, and every year scientists worry that it may disappear. Joint captive breeding programs of freshwater fishes--cichlids, rainbow fish, killy fish--and frogs that face extinction from habitat degradation have been established in conjunction with institutions in Madagascar, with which Academy staff have a long association. Under the guidance of Steinhart aquarists, these animals will be bred both at the aquarium and in their native country. “Attract, intrigue, inform, involve” is the Academy’s motto. How far along this ladder each visitor climbs will vary, but if the Steinhart achieves its purpose, many will reach the top and come back as volunteers or move on to assist similar organizations with their conservation goals. Although most visitors will come to the Academy and aquarium looking for enjoyment, the Steinhart staff hopes that they will leave motivated to help protect our aquatic world. As the Water Planet display tells us, water is life.
