A public aquarium (plural: public aquaria or public aquariums) is the aquatic counterpart of a zoo, which houses living aquatic animal and plant specimens for public viewing. Most public aquariums feature tanks larger than those kept by home aquarists, as well as smaller tanks. Since the first public aquariums were built in the mid-19th century, they have become popular and their numbers have increased. Most modern accredited aquariums stress conservation issues and educating the public.
The first public aquarium was opened in London Zoo in May 1853; the Fish House, as it came to be known, was constructed much like a greenhouse. P.T. Barnum quickly followed in 1856 with the first American aquarium as part of his established Barnum's American Museum, which was located on Broadway in New York before it burned down. In 1859, the Aquarial Gardens were founded in Boston. A number of aquariums then opened in Europe, such as the Jardin d'Acclimatation in Paris and the Viennese Aquarium Salon (both founded 1860), the Marine Aquarium Temple as part of the Zoological Garden in Hamburg (1864), as well as aquariums in Berlin (1869) and Brighton (1872).
The old Berlin Aquarium opened in 1869. The building site was to be Unter den Linden (along a major avenue), in the centre of town, not at the Berlin Zoo. The aquarium's first director, Alfred Brehm, former director of the Hamburg Zoo from 1863 to 1866, served until 1874. With its emphasis on education, the public aquarium was designed like a grotto, part of it made of natural rock. The Geologische Grotte depicted "the strata of the earth's crust". The grotto also featured birds and pools for seals. The Aquarium Unter den Linden was a three-story building. Machinery and water tanks were on the ground floor, aquarium basins for the fish on the first floor. Because of Brehm's special interest in birds, a huge aviary, with cages for mammals placed around it, was located on the second floor. The facility closed in 1910.
The Artis aquarium at Amsterdam Zoo was constructed inside a Victorian building in 1882, and was renovated in 1997. At the end of the 19th century the Artis aquarium was considered state-of-the-art, as it was again at the end of the 20th century.
Prior to its closing on September 30, 2013, the oldest American aquarium was the National Aquarium in Washington, D.C., founded in 1873. This was followed by the opening of other public aquariums: San Francisco (Woodward's Garden, 1873–1890), Woods Hole (Science Aquarium, 1885), New York (Battery Park, 1896–1941), La Jolla (Scripps, 1903), Honolulu (Waikiki Aquarium 1904–present), Detroit (Belle Isle Aquarium, 1904–2005, 2012–Present), Philadelphia (Fairmount Water Works, 1911–1962), San Francisco (Steinhart Aquarium, 1923), Chicago (Shedd Aquarium, 1929). For many years, the Shedd Aquarium in Chicago was the largest aquarium in the United States, until the Georgia Aquarium in Atlanta opened. Entertainment and aquatic circus exhibits were combined as themes in Philadelphia's Aquarama Aquarium Theater of the Sea (1962–1969) and Camden's re-invented Adventure Aquarium 2005, formerly the New Jersey State Aquarium (1992).
In 2005, the Georgia Aquarium, with more than 8 million U.S. gallons (6.7 million imp gal; 30 million L) of marine and fresh water, and more than 100,000 animals of 500 different species opened in Atlanta, Georgia. The aquarium's notable specimens include whale sharks and beluga whales.
Public aquariums today
Modern aquarium tanks can hold millions of litres of water and can house large species, including dolphins, sharks or beluga whales. This is accomplished through thick, clear acrylic glass windows. Aquatic and semiaquatic mammals, including otters, and seals are often cared for at aquariums. Some establishments, such as the Oregon Coast Aquarium or the Monterey Bay Aquarium, have aquatic aviaries. Modern aquariums also include land animals and plants that spend time in or near the water.
For marketing purposes, many aquariums promote special exhibits, in addition to their permanent collections. Some have aquatic versions of a petting zoo. The Monterey Bay Aquarium has a shallow tank filled with common types of rays which visitors are encouraged to touch. The South Carolina Aquarium lets visitors feed the rays in their Saltmarsh Aviary exhibit.
Most public aquariums are located close to the ocean, for a steady supply of natural seawater. An inland pioneer was Chicago's Shedd Aquarium that received seawater shipped by rail in special tank cars. The early (1911) Philadelphia Aquarium, built in the city's disused water works, had to switch to treated city water when the nearby river became too contaminated. Similarly, the recently opened Georgia Aquarium filled its tanks with fresh water from the city water system and salinated its salt water exhibits using the same commercial salt and mineral additives available to home aquarists. The South Carolina Aquarium pulls the salt water for their exhibits right out of the Charleston harbor.
In January 1985, Kelly Tarlton began construction of the first aquarium to include a large transparent acrylic tunnel, Kelly Tarlton's Underwater World in Auckland, New Zealand. Construction took 10 months and cost NZ$3 million. The 110-metre (360 ft) tunnel was built from one-tonne (2,200-lb) slabs of German sheet plastic that were shaped locally in an oven. A moving walkway now transports visitors through, and groups of school children occasionally hold sleepovers there beneath the swimming sharks and rays.
Public aquariums are often affiliated with oceanographic research institutions or conduct their own research programs, and sometimes specialize in species and ecosystems that can be found in local waters. For example, the Vancouver Aquarium in Vancouver, BC is a major center for marine research, conservation, and marine animal rehabilitation, particularly for the rich ecosystem of the Pacific Northwest. The Vancouver Aquarium was the first aquarium to capture and display an orca whale, Moby Doll, for three months in 1964; as well as belugas, narwhals and dolphins.
