Tokyo Sea Life Park has its origins in "Uonozoki", the first Public aquarium in Japan that was opened in 1882.[1] It is a public aquarium that existed only during the exposition and was closed at the end of the exposition.[1] After that, uonozoki was demolished, but in 1929, the Ueno Aquarium was opened in the same place at Ueno Zoo. In 1952, aquariums started breeding saltwater fish based on the experimental results of filtration equipment, etc., and opened the New Ueno Aquarium in 1964. New Ueno Aquarium is one of the aquariums that started to use acrylic glass for large tanks in earnest. In 1964, acrylic panels with a height of 2 metres (6.6 ft), a width of 18 metres (59 ft), and a thickness of 7 centimetres (0.23 ft) were installed.[1]
After that, in commemoration of the 100th anniversary of Ueno Zoo, formulated a plan to build the largest aquarium in Japan. It officially opened in 1989 as Tokyo Sea Life Park.[1]
All the creatures kept in the ueno aquarium were inherited by Tokyo Sea Life Park and the ueno aquarium was closed.[1]
Overview
donut-shaped tank
Approximately 650 species of organisms are bred in 47 tanks, including tuna that migrate around large donut-shaped tank.
At the beginning of the park, it was the largest and most popular Public aquarium in Japan, and the annual number of visitors in the first year of the park was 3.55 million, far exceeding the Japanese record at that time (2.4 million at Kobe City Suma Aqualife Park Kobe: 1987). After that, the record was not broken until Osaka Aquarium was created.
The world's first successful exhibition of nurseryfish. In addition, many of the exhibited creatures are directly collected locally by the Research Section of the Breeding and Exhibition Division, and rare creatures can be seen especially in polar aquariums.
It is open for free on May 4, May 5, October 1, and October 10.
Renewal
As the facility is aging 30 years after its opening, aquariums have begun to consider the construction of a new facility and the ideal aquarium. Aquariums soliciting opinions from the citizens of Tokyo at the end of 2018. In January 2019, aquariums formulated the basic concept of building a new facility on the premises. Then, in February 2020, a study group of experts approved the rebuilding plan report. The scale is expected to have a total floor area of about 22,500 square meters and maintenance costs of 24 to 27 billion yen.[3] A business plan will be formulated by the end of 2020, and it is expected to open in 2026.[4]
Many aquariums only show the names and figures of the fish, but there are also pictorial books and rooms with specialized staff for research. As a service improvement, a commentary using a digital photo frame panel was added next to the aquarium in May 2011.
Japan's first Pacific bluefin tuna, Scalloped hammerhead
Succeeded in long-term captivity and exhibition by preparing the collection, transportation and breeding environment. Bluefin tuna with weak skin paid close attention to collection and transportation, and realized a group swimming exhibition.[1]
aquariums have also established a method for growing large seaweeds that require good water quality, water flow, and sufficient light, such as Giant kelps, in a closed indoor tank. Seaweed captivity has a friendly tie-up with Monterey Bay Aquarium.[1]
The two blue sharks started captivity in 1999 and inhabited for 210 and 246 days. This was the longest captivity record until it was overtaken by the Sendai Umino-Mori Aquarium.[5] Also, in 2020, aquariums started captivity two blue sharks and inhabited them for five months.[6]
"Four species" of "Penguins Ecology" (Humboldt penguins, king penguins, rockhopper penguins, and fairy penguins are bred outdoors. However, king penguins and rockhopper penguins Since it is vulnerable to the heat of summer in Japan, it is bred indoors with a cooling facility in the summer and is not open to the public.)
"Seaweed forest" (Exhibition centered on giant kelp)
In 2007, he also succeeded in Spawning of Leafy seadragon.[8]
Humboldt penguins and Little penguins will work at JAZA member buildings.
I am in charge of breeding adjustment, and I am making adjustments so that the pairing is genetically appropriate. Japanese fire belly newt is also known as Ueno Zoo, Tama Zoological Park, and Inokashira Park Zoo.
The habitat is conserved jointly by the four gardens.
In addition, the results of research and research in a wide range of fields are utilized for exhibitions.
aquarium conducting surveys and research on the breeding of aquatic organisms by accumulating his how and data through research and research on food, habitat, breeding environment etc, and inspection and dissection of dead individuals. Aquarium is focusing on the breed of bluefin tuna, and spawning was confirmed for the first time in the world in a closed tank on land.[9]
aquariums working on continuous monitoring of the natural environment in Tokyo, jointly researching water quality maintenance technologies such as denitrification with companies, and improving breeding environment technologies.[1]
Ocellated Ice Fish
Ocellated Ice Fish
On February 12, 2013, The Ocellated Ice Fish (Channichthyidae, Chionodraco rastrospinosus) spawned in captivity for the first time in the world. There were about 500 eggs with a diameter of about 4.5 mm. The time when the eggs hatched is unknown, and the aquarium speculated that "if it is about the same as other Antarctic fish, it will be six months later."[10][11] This is the world's first example of Breeding a Ocellated Ice Fish.[12]
Accident
Escape of Penguin 337
The aquarium received global attention in 2012 when one of its 135 Humboldt penguins thrived in Tokyo Bay for 82 days after apparently scaling the 13 foot high wall and managing to get through a barbed-wire fence into the bay.[13] The penguin, known only by its number (337), was recaptured by the keepers in late May 2012.[14]
Tuna and skipjack tuna wiped out in 2015
Yellow tape is regularly applied to prevent collisions with tuna and other fish.
As of December 1, 2014, 63 bluefin tuna, 67 Mackerel tuna, and 35 Striped bonito were kept in a large tank for migratory fish, but from the beginning of the same month, these individuals died one after another. Mackerel tuna on January 18, 2015, Striped bonito on January 26 of the same year, and as of January 26, only 3 bluefin tuna The bluefin tuna were also wiped out on January 26, 2015, leaving only 3 bluefin tuna.[15][16] The cause has not been determined, but pathological tests have revealed the virus in spleen cells of bluefin tuna and Mackerel tuna.[17]
One more died on February 25, and another on March 24, leaving only one remaining. In April 2016, Aquarium announced the final results of its investigation, which indicated that the mass mortality was not caused by a single factor, but by the multilayered and combined effects of multiple direct and indirect factors. The view was expressed.[18][19][20]
After consultation with various experts, measures were taken to address several factors that were thought to have contributed to the problem. These have since been phased out, with tuna being brought in, and the situation has returned to a state similar to that prior to 2014, but without the mass mortality trends seen in previous years.[21]
