To those who gave valuable advice to the Port of Nagoya Public Aquarium
We would like to express our thanks to many people for giving us valuable advice about how Killer whales should be kept at the Port of Nagoya Public Aquarium. Our basic attitude toward keeping and exhibiting animals at the Aquarium has remained unchanged since the Aquarium's founding. Although ideally we should explain this attitude to all of you personally, it would be appreciated if you would allow us to explain here on the Web, and understand and cooperate with our activities. The following are our activities and our attitude toward them.


Activities of the Port of Nagoya Public Aquarium
Since its founding in 1992, the Port of Nagoya Public Aquarium, well aware of the importance of protecting, preserving and breeding wildlife, has served not only as a social educational and recreational facility to exhibit animals to the public, but also as a research facility to study the ecology of endangered species, and has engaged in various activities to breed and protect such species.

(1) Breeding of sea turtles and penguins
@ The Port of Nagoya Public Aquarium, equipped with a unique institute for the study of sea turtles and an artificial nesting ground (sandy beach) connected to a circular tank for sea turtles, has succeeded for the first time in history in having Loggerhead and Hawksbill turtles lay eggs and in hatching the eggs in captivity. From the opening of the Aquarium until last year, of 7,500 eggs laid at the Aquarium, 4,650 were hatched. With 1,500 eggs laid last year, and 80% of them hatched, the hatching rate is increasing year by year. In addition, various social education programs have been promoted. These programs include inviting the public to the Aquarium at night to observe sea turtles laying eggs, and providing the public to release Loggerhead turtle hatchlings into the Pacific Ocean from local nesting beach such as Akabane Beach, Atsumi Peninsula, Aichi Prefecture, under the supervision of staff members of the Aquarium.
Meanwhile, the Aquarium has a dioramic display tank for penguins that recreates the meteorological environment of the Antarctic Circle for keeping and exhibiting four species of arctic penguins: Emperor penguins, Gentoo penguins, Chinstrap penguins and Adelie penguins. The Aquarium has gained a worldwide reputation for its success in breeding three of these penguin species (excluding Emperor penguins). Chinstrap and Adelie penguins were here successfully reproduced for the first time in Japan.

(2) Other animals bred at the Aquarium
@ In addition to sea turtles and penguins, the Aquarium has succeeded in breeding various animals, including Antarctic krill, here bred for the first time in the world. In the hope that our achievements will be shared with people all over the world, we will continue to pursue our research.


Roles of the Facility Built in the new facility
(1) Significance of the facility
@ The new facility was completed in the second-stage construction project. A greater range of exhibits are displayed at the new facility, based on the Aquarium's achievements and research results, without harming the continuity between this facility and the preexisting facility, which has "Journey to the Antarctic" as its theme. The new facility has two major objectives: to give visitors a close look at large marine mammals (Cetacea), animals familiar to the Japanese since ancient times, so that they will develop a greater appreciation for the value of life and learn about the ecology of wildlife; and to further develop our research activities in breeding and protecting various species.
Under the theme "3.5 Billion Years\Long Journey, Animals that Have Returned to the Sea," the new facility introduces the relation between human beings and whales, which have won the long struggle for survival. We hope that this facility will give visitors an opportunity to think about the coexistence of whales and human beings in the global environment of the 21st century.
As a whole, this facility reflects public views expressed through the assembly of the Nagoya Port Authority, the construction promoter of the facility, in the process of designing the project.
@ @
(2) Animals exhibited at the new facility
@ Originally, Killer whales, Bottle-nosed dolphins and Belugas were on the list of species to be bred and exhibited at the new facility. Unfortunately, however, Killer whales, a species that many citizens asked us to exhibit at the Aquarium, could not be acquired prior to the opening of the new facility last November. We will do our best to live up to their expectations. We are considering obtaining Killer whales on breeding loan from other aquariums, and capturing wild ones. Any killer whales obtained will be kept and exhibited at the facility with the world's most advanced equipment.
@ @
(3) Breeding environment
@ In keeping animals, ample attention is directed toward preserving and breeding of species. Separate pools are used for display, breeding and medical treatment of animals by species. In addition, with one of the world's largest pools (water volume: 13,400 t, dimensions: 60 m (length) ~30 m (width) ~12 m (depth)), the new facility is capable of keeping four to six Killer whales, a dozen Bottle-nosed dolphins, and four to six Belugas.
Furthermore, with well-equipped medical care, quarantine and research facilities, the Aquarium gives ample consideration to the breeding environment.

(4) Our policy on exhibiting animals
@ In exhibiting animals, importance is given to two points: one is that the behavior and ecology inherent in individual animals should not be upset; the other is that marine animals should be exhibited so that visitors can observe their behavior and ecology, and how they communicate in water. Therefore, underwater view windows (observation windows, dimensions: 4 m ~29 m) are provided at the bottom portion of the side of every water tank.
Meanwhile, animal shows organized at the Aquarium, unlike conventional shows, feature the use of a large screen (LED hi-vision displays, dimensions: 8 m ~14 m) helpful to the audience in understanding the significance of each action taken by animals, and their ecology.
@ @
(5) Research activities
@ In the process of breeding large marine mammals in its possession, the Port of Nagoya Public Aquarium has been preparing to implement research plans that are impractical without captive animals. Specific subjects of these research plans include:
@E Research on conservation of species, that is, physiology for reproduction and biology, and artificial insemination techniques
@E Research on communication in water
@E Research on cognitive ability (cognitive science)
@E Research on social and environmental education programs based upon the relation between human beings and marine mammals
@E Research on animal-assisted therapy using animals in captivity
From the global perspective, the Aquarium will conduct joint researches and field surveys in collaboration with universities, research institutes and other aquariums.

Roles of the Port of Nagoya Public Aquarium
Using earth's biological resources under appropriate control, without depleting them (sustainable use of resources), is essential to the survival and development of human beings; this fact is acknowledged by people around the world.
Accordingly, there is growing demand for environmental education that helps us understand the importance of preserving wild animals, including marine mammals, and using them effectively as biological resources.
In satisfying these demands, the roles of aquariums and zoos have increased in importance, because they can offer knowledge that is of help in creating the new worldview essential to successful co-existence of human beings and nature. The Port of Nagoya Public Aquarium is determined to make every effort to contribute to this endeavor.
