The Duisburg Zoo was on 12 May 1934 by Duisburg established citizens. The zoo is known for its dolphinarium and the first permanent and for a long time the only one in Germany, and to this day the only breeding of koalas . In addition, numerous zoological rarities are kept, such as B. Giant otters or an Amazon dolphin from South America, colobus monkeys and brush-eared pigs from Africa, fossas from Madagascar, clouded leopards from Asia or wombats from Australia.
Location and arrival
The zoo is located on the northern edge of the Duisburg city forest on the border with Mülheim an der Ruhr and touches the northern campus of the University of Duisburg-Essen . The federal highway 3 separates the zoo into a western and an eastern part, which are connected by a landscaped bridge. The motorway is not visible, but can be heard. Visitors can arrive by car via the Duisburg-Kaiserberg exit. Line 901 of the Duisburg tram stops at the entrance and connects with the main train stations in Duisburg and Mülheim . The area of the zoo is around 16 hectares.
history
The founding years of the Duisburg Zoo
The Duisburg Zoo was founded in 1934 as the Duisburg- Hamborner Tierpark on the initiative of the Duisburg Zoo Association. The first director was Eduard Wiedemann , who, however, moved to the Wuppertal Zoo in 1942/43 , whereupon the zoo was provisionally managed by the board of the zoo association until 1946. Initially, primarily native animal species were presented on an area of barely more than one hectare. By the beginning of the Second World War , the zoo was expanded to over eight hectares and the animal population was also expanded considerably. During the Second World War, most of the zoo's facilities and buildings were badly damaged or completely destroyed, so that the zoo had to be closed. At the end of the war in 1945 only one emu , three flamingos , and a few donkeys, goats and sheep survived .
Reconstruction after the Second World War
Under the new director Hans-Georg Thienemann, who came to Duisburg from the Königsberg zoo in 1946 , the zoo had to be completely rebuilt after the war. The animal population was able to be replenished, among other things, by lending animals from the Hellabrunn Zoo in Munich . New facilities for tarpans , Przewalski horses , cattle and bison , among others , were quickly built, and their basic structure is still preserved today.
As early as 1951, the zoo's former jewel, the aquarium , was reopened and is now considered the zoo's oldest surviving building. Another milestone in the development of the zoo was the opening of the large mammal house for elephants and giraffes in 1953, which today, enlarged and modernized, is used exclusively for keeping elephants.
Also in the 1950s, the outdoor facilities with dry trenches that were typical of the Duisburg Zoo at the time were built. B. Bactrian animals and David deer , as well as the facilities for seals and penguins on an expansion site at the northern end of the zoo , which were inaugurated in 1958 by the entrepreneur and sponsor of the zoo, Helmut Horten .
Development into a modern zoo
In 1959 the corporate form was converted into a stock corporation, with the city of Duisburg (73%) and the zoo association as the main shareholders. In the same year, an additional area of around five hectares was gained beyond the Duisburg-Wedau-Bottrop Süd railway line and the federal highway 3 , so that the total area of the zoo expanded to over 15 hectares. The new area was opened up via the so-called Expo Bridge of the World Exhibition in Brussels .
The zoological highlight of the new site was the equatorium, which opened in 1962 and was the largest and most modern monkey house in the world at the time. Another highlight was the opening of the first dolphinarium in Central Europe on the newly developed area in 1965. The keeping and research of bottlenose dolphins increased the zoo's reputation because dolphins were only known from television at the time.
The success with the bottlenose dolphins moved Wolfgang Violence , who succeeded Director Thienemann, who died in 1965, in 1966, to build a second dolphinarium in 1968 and to establish more species of dolphins at Duisburg Zoo. In 1969, in independently managed, criticized and unimaginable fishing expeditions, Wolfgang brought white whales (also known as belugas) to Duisburg in 1969 , which were later followed by Jacobita dolphins (also called Commerson dolphins ) from other expeditions , which together with the white whales in the Walarium were housed. From another expedition to South America, violence brought the unique Amazon dolphins to Duisburg.
Due to the dilapidated condition of the aging walarium, the white whale “Ferdinand” and the Jacobita dolphin “Yogi”, the last of their species in Duisburg, were flown to SeaWorld in San Diego (USA) in the summer of 2004 , where they came together should spend their old age with conspecifics. Despite their great age - both animals were already among the oldest known animals of their kind at this point in time - both survived the transport well. While Yogi died a few months later at an old age, Ferdinand is still alive and is now around 50 years old as the oldest known white whale in the world (as of 2020) . After the belly whales and Jacobita dolphins were released and the walarium was closed, Duisburg Zoo concentrated on keeping bottlenose dolphins and river dolphins.
In 1970 the Duisburg zoo was officially renamed the Duisburg Zoo. The reputation increased from year to year. Not only did many first-time breeders of rare animal species such as marsupial devils , spoonhounds or tree kangaroos contribute to this, but also some innovative systems such as the "run-and-fun" system for African wild dogs , the bird forest, the large predator house, the bear enclosure or the gut one hectare Chinese garden with cranes and small pandas as a gift from Duisburg's twin city Wuhan .
The planning of the third dolphinarium, which was opened in 1995 under his successor Reinhard Frese as the most modern roofed dolphinarium in Europe, was the end of the era of Wolfgang Violence.
Transition into the 21st century
During Reinhard Frese's time as director, it was important to set up Duisburg Zoo for the 21st century and to replace old, outdated facilities with modern new buildings, which also led to the fact that some species such as z. B. polar bears or chimpanzees had to be handed in. Old cage units gradually disappeared, such as the so-called rarities cabinet (the zoo's first ape house at the time) or the many small predator cages. Spacious, natural-looking facilities for turtles , otters , coatis , arctic foxes , wolverines and fossas , among others , have been created .
The former large mammal house was converted into a modern elephant complex, while the giraffes received a new facility at the main entrance to the zoo. There was also a large ring- tailed lemur that visitors can walk into . The equatorium has been significantly upgraded with a new outdoor area for gorillas and two new entrance areas with integrated systems for colobus monkeys and pygmy hippos .
With the beginning of koala keeping in 1994, the Duisburg Zoo established another important unique selling point in addition to the keeping of dolphins. Only the Tierpark Berlin received the first two koalas in Germany just under a month before the Duisburg Zoo in 1994, which were shown for four and a half months as part of a shutdown at the San Diego Zoo . For the next 19 years, koalas could only be seen in Duisburg Zoo in Germany. In November 2013, Dresden Zoo received two male koalas from the Duisburg breed. This makes this zoo the second in Germany to show these animals. In 2016, Leipzig Zoo followed as the current third keeper in Germany.
In 1997, the old Expo bridge over the Duisburg-Wedau-Bottrop Süd railway line and federal motorway 3 had to give way . It was replaced by a new landscape bridge up to 30 meters wide, which now connects the two sides of the zoo, isolated from the noise of the two traffic routes. The lettering "ZOO", which is formed from a hedge, is visible from the motorway. The Expo bridge was rebuilt a few hundred meters further south of the old location; today it connects the Duisburg campus of the University of Duisburg-Essen with the Duisburg city forest . It only crosses the autobahn, but still serves as a landmark for drivers from the south as the start of the Ruhr area .
In 2005 the zoo opened the tropical hall Rio Negro, which offers sloths , marmosets and toucans, among other things, a large pool complex for the unique Amazon dolphins native to the rivers of South America. Today the male “Butu” still lives there as the last representative of this species outside of South America, after his much older partner “Apure” died of old age in 2006 at the age of well over 40 as the oldest known river dolphin.
At the beginning of 2007 the long-time deputy director Achim Winkler took over the management of the zoo, with the aim of continuing the modernization of the last few years. New systems were built for wombats, turtles, giant otters and meerkats as well as a large petting zoo and a modern wood chip heating system . In 2007, the breeding of two bottlenose dolphins at the same time was achieved for the first time as a significant breeding success, and in 2008 for the first time in Duisburg Zoo, the breeding of gorillas, also with two young animals.
After a five-year sponsorship contract with RWE AG expired on March 31, 2013 without renewal and the airline Air Berlin temporarily stopped sponsoring the zoo, the city of Duisburg had to increase its annual subsidy from 2.2 million euros (initially one-off) to 3.2 Increase million euros to ensure the zoo's liquidity. Against the background of the desperate financial situation of the city of Duisburg as the owner of the zoo, a considerable investment backlog in the zoo infrastructure and massive protests by animal rights groups against the zoo keeping of dolphins, which are one of the main attractions in the Duisburg zoo and in Germany next to Duisburg only in the zoo Nuremberg , the medium and long-term existence of the Duisburg Zoo is unsecured. For 2015, 2.1 million euros were earmarked in the city's draft budget.
In December 2016, 49-year-old Hans Köppen was elected as the new zoo director. He should take office on June 1, 2017. Barely four weeks later, he canceled for personal reasons. When Astrid Stewin took office as the new Commercial Director on November 1, 2017, the Chief Executive Officer will be the Commercial Director for the first time. The previous chairman ("zoo director") Winkler remained until his departure at the end of July 2018 as a member of the board of the AG and zoological-technical director. In August 2018, the 29-year-old Johannes Pfleiderer, who had previously worked as a curator at Duisburg Zoo since February 2016, took up his post as zoological director.
In 2020, the zoo published a master plan that provides for investments of around 76 million euros. Among other things, a savannah facility is to be built in which giraffes, zebras and antelopes should live; until now they have been living in separate enclosures. This should give the animals more space, which complies with the mammal certificate and opens up new opportunities for animal employment. Thanks to a natural design, the facility should also be more attractive for visitors. In addition, the zoo wants to further expand its Australian focus, for example an Australian house for koalas, marsupial devils and wombats and an outback aviary with Australian birds and mammals are to be built. The creation of further plants and the acquisition of new species such as tree kangaroo and cassowary is also possible. The future of elephant husbandry is unclear. At the moment only cows are kept and under the current conditions the establishment of a breeding herd is excluded from the EEP . The elephants may leave the zoo. In addition, the zoo is planning the establishment of a "seal area". The facility for the Californian sea lions is to be expanded to include the current facilities for the African penguins and arctic foxes, as well as the former polar bear enclosure. The penguins could move to the current seal facility. The equatorium is also to be revised, the primate enclosures are to be enlarged and improved and the animal population is to be adapted to the available space, whereby one would like to concentrate on a few main species. In addition, new educational rooms and a playground are to be created. Dolphin husbandry is considered controversial, but the zoo does not want to do without successful dolphin husbandry and breeding. In this regard, the sliding roof of the dolphinarium is to be renewed and the filter system renovated. Accessibility measures are also planned. In addition, a new zoo restaurant and event rooms are to be built.

The most important enclosures
Dolphinarium
The Dolphinarium consists of the New Dolphinarium, which was opened in 1995, and the Old Dolphinarium, which is not accessible to visitors, consists of a main and several secondary pools, which is also used as a quarantine station in the event of births and diseases, as well as a swimming passage that connects both areas.
The dolphinarium is inhabited by the seven bottlenose dolphins "Ivo", "Pepina", "Delphi", "Daisy", "Dörte", "Debbie" and "Dobbie", who live in a pool complex that holds approximately three million liters of lake water . The pool water is not cleaned chemically, but in a purely biological way with special protein skimmers developed by the Duisburg Zoo in cooperation with the Jülich Research Center with the addition of ozone .
It is one of the last dolphinariums in Germany. Depending on the time of year, there are two to three screenings a day in the large arena, which can accommodate 1,400 visitors. The dolphinarium is open to visitors free of charge between the performances during the week (not on Sundays and public holidays). There are regular promotions such as B. “An evening with dolphins”, “Zookeeper for a half day” or “Children's birthdays”.
Eleven young dolphins have been raised in Duisburg several times since they were first bred in 1978: Duphi (1988, now deceased), Delphi (1992, daughter of Flapine), Daisy (1996, daughter of Pepina), Duke (2001, son of Pepina, died in the meantime ), Donna (2007, daughter of Pepina, moved to Nuremberg Zoo since 2014 ) and Dolly (2007, daughter of Delphi, also moved to Nuremberg in 2014), Diego (2011, son of Pepina, moved to Lanzarote in 2016), Dörte (2011, Daughter of Delphi) and Darwin (2011, son of Daisy, moved to Lanzarote in 2016), Debbie (2015, daughter of Delphi) and Dobbie (2016, son of Pepina). Dolly is the first dolphin in the Duisburg Zoo, who was born in the second generation, as the mother Delphi was also born in the zoo. In 2011 and 2015 Delphi became a mother again and Daisy, who was born in Duisburg in 1996, also had a young animal. Thus, four second generation dolphins were born in Duisburg. Even today, the offspring of dolphins is proving to be very difficult, as newborn dolphins do not have a pronounced immune system and are therefore very susceptible to pathogens. To protect the young animals, the old dolphinarium from 1968, which is connected to the new one from 1995 via a swimming channel, was converted into a quarantine unit, where mother and young animal can live protected from pathogens during the first few weeks of life.
In the five years from 2007 to 2013 inclusive, the facility was called RWE -Delfinarium . The corresponding sponsorship contract with RWE AG expired, on the basis of which the zoo was supported with one million euros annually.
Almost all dolphins that live in Duisburg today were born there. Two bottlenose dolphins that were caught in the early 1980s and came to Duisburg in 1992 and 1999, respectively, still live from those caught in the wild. IN Duisburg more dolphins were born than died in this century. This makes breeding sustainable.
Chinese garden
The Chinese garden of the Duisburg Zoo is a gift from Duisburg's twin city Wuhan , which was built in 1988 with original materials from China . In addition to a characteristic Chinese garden design with large ponds and all kinds of typical plants, such as. B. lotus blossoms, cherry trees and various bamboo grasses, typical Chinese buildings such. B. the entrance and mountain pavilion, the hall of happiness, the water pavilion or the arched bridge. The Chinese garden, also known as the garden of the crane, is home to some animal species from the Far East, such as Sarus and Red-crowned cranes as well as muntjacs and small pandas.
Rio Negro
The tropical hall Rio Negro , opened in 2005, represents a section of the South American jungle. The centerpiece is the pool complex for the very rare freshwater native Amazon dolphin . The pool is designed to be close to nature and is separated from the visitor area by a curved glass pane over eight meters long. The hall has a natural design, partly with a wooden chipboard floor, a wooden lookout in the treetops, many plants and free-range animals such as tamanduas , sloths , marmosets, various species of birds and reptiles. The tropical hall is connected to the adjacent aquarium via a visitor tunnel. From the tunnel you have a glimpse into the interior of the giant otters' enclosure, which was redesigned in 2008 and which extends outside with a large water and land section to the entrance of the tropical hall. In 2009, the Duisburg Zoo succeeded in breeding the rare giant otter for the first time .
Koala house
In 1994 the Duisburg Zoo broke new ground with the presentation of koalas . Previously, keeping koalas in Central Europe was considered impossible due to feed logistics. As pronounced food specialists, koalas are dependent on fresh eucalyptus leaves , which are not available all year round in Central Europe. Only thanks to an agreement with the airline LTU (taken over by Air Berlin in 2007 ), which flies the required eucalyptus food in from a special plantation in the USA on a weekly basis, was it possible to guarantee permanent koala keeping. These deliveries were suspended in 2013 but resumed in 2014.
The koalas are separated from the visitors by a pane of glass. In the visitor room you can find information about koalas and Australia, as well as the story of how the koalas got to the zoo. In addition, there is a permanent photo exhibition by nature photographer Ingo Öland in the Koala House, which shows Australia's landscapes and wildlife on 22 large-format motifs. In 1995, the first successful koala rearing in Europe was achieved at Duisburg Zoo. Since then, a young animal has been raised almost every year, so that today the Duisburg Zoo is one of the leading keepers of koalas worldwide. In the outdoor area, the koalas can be observed without a partition.
Fossa appendix
The fossa system is intended to simulate the natural habitat of the fossa with lots of vegetation and small water systems. The breeding successes are considered to be the greatest worldwide.
The zoo has been coordinating the European Endangered Species Program (EEP) since 1994 and the International Studbook for this species since 2000.
The Fossa facility was donated in 2000 by the Duisburg Zoo Friends Association. Protection projects in Madagascar are financed through a fossa fund initiated by the Duisburg Zoo.
Equatorium
The equatorium, which dates back to 1962, is still considered to be one of the largest monkey houses in the world with an outstanding population of monkeys , from pygmy marmosets to gorillas . The name of the house refers to the fact that animals from the equatorial region are kept - in addition to monkeys, sloths, iguanas, turtles, pygmy hippos and parrots. For some years now, the equatorium has been renovated and redesigned bit by bit.
In 2002 the Gorilla Bush, a large outdoor enclosure for lowland gorillas and Brazza monkeys , was opened. The new east entrance, donated by ThyssenKrupp , opened in autumn 2005 , behind which you can see mountain loris in an aviary that can be walked under supervision, as well as the rare colobus monkeys.
The west entrance opposite was completely redesigned in 2001 with the support of Duisburger Stadtwerke and contains a modern facility for pygmy hippos . In December 2014 the male pygmy hippopotamus “Nokoko” was born - a rare and important event for breeding, because most of the pygmy hippos are females.
The equatorium and the dolphinarium have been heated by a modern wood chip heating system since 2010 .
Outdoor turtle enclosure
In 2006, the outdoor area of the Rio Negro tropical hall was created as an enclosure for tortoises. The south-facing enclosure is based on the natural habitat of the turtles. There is a natural stream and many stone caves and other shelters as a retreat. There are also a few plexiglass heated huts in the facility, into which the turtles can retreat at any time to warm up.
The turtles feed on the lush and diverse vegetation in the facility. Next door is another turtle facility with a greenhouse as a warm house and a large pond for ornamental turtles and giant turtles.
Zoo bridge
Since the 1960s, the Duisburg Zoo site has been stretching on both sides of the Duisburg-Wedau-Bottrop Süd railway line and the Federal Motorway 3 . The Expo Bridge , a narrow pedestrian bridge with a 50 meter high steel pylon, which became the architectural symbol of the city of Duisburg, served as a connection between the two halves of the zoo .
Due to the expansion of the federal motorway 3 to a total of six lanes, the Expo bridge had to be replaced in 1997, and it was decided to use a landscape bridge up to 30 meters wide. The hallmarks of the new zoo bridge are larger-than-man-size trees that have grown and trimmed in the shape of the letters ZOO and draw the attention of drivers to Duisburg Zoo from afar from the motorway.
Adventure world
In 2011 a large petting zoo was opened, which was combined with the adjoining children's playground to form the new Sparkasse adventure world . In addition to the playground, the area offers a large farm with domestic animals, an African kraal with sheep and goats, a South American enclosure with alpacas , a natural pond and a large house for explorers with various animal species. The focus of the adventure world is the development from wild animals to domestic and farm animals.
Spectacled bear enclosure
In place of the old Kodiak bear facility from the early 1980s, a much larger, natural-looking facility for South American spectacled bears was opened in 2012 , which was largely financed with funds from the zoo's friends' association. Various viewing niches, including over a pond, from visitor huts or through high viewing windows, open up the lush enclosure, which is equipped with climbing trees, to visitors.
The first offspring were born in October 2013. The zoo celebrates the success of breeding as a sensation, because spectacled bears are among the critically endangered species: around 70 animals currently live in European zoos, and only four to five young animals are born there each year.
Giant salamander plant
On June 17th, 2014, a new, natural facility for Chinese giant salamanders was inaugurated. The replica of a Chinese mountain section with a stream and rocks cost around 150,000 euros. A wide glass front provides insights. The Chinese giant salamander ( Andrias davidianus ), an archaic amphibian species, can grow up to 180 centimeters long and weigh up to 50 kilograms.
Aquarium
In July 2015, after three years of renovation, the aquarium, the zoo's oldest surviving building, was reopened. The architecture of the house was hardly changed, but the entire building was technically brought up to date, energetically paid attention to sustainability and energy saving, and the pools have been extensively renewed.
The largest tank is a 22,000 liter reef tank with more than 1,500 fish. Also new are a 120 centimeter jellyfish spinning top, a seahorse pool and a waterfall pool. In addition, the themed pools have been redesigned, in which the various habitats are shown from the source to the sea.
Tiger enclosure
The new facility for Siberian tigers opened in March 2016 was followed by the birth of the twins “Makar” and “Arila” in June.
Incidents
On the evening of August 31, 2015, an orangutan was able to get into a neighboring enclosure through an improperly secured gate. He got into an argument with the male there, whereupon he escaped in panic through a skylight. While trying to climb over the outer fence of the zoo, he was shot dead by a zoo employee who was authorized to shoot, as it was feared that an anesthetic shot would be too slow for the ape to reach the street outside the zoo. The police and fire brigade, who had moved to be on the safe side, did not need to intervene. Since the outbreak took place after the zoo's regular opening hours, there was no danger for zoo visitors, as they were no longer on the premises at that time.
Ruhrpott snouts
The ZDF broadcast the documentary series “Ruhrpott-Schnauzen” from June 2006 with a five-month break. It ran Monday to Friday from 3:15 p.m. to 4:00 p.m. and reported on stories from the Duisburg Zoo. The broadcast of the previous season ended on July 8, 2008.
From October 20, 2008 to August 13, 2010, the Duisburg Zoo (in addition to the Zoom Erlebniswelt Gelsenkirchen , Wuppertal Zoo , Marine Museum and Ozeaneum Stralsund , Schönbrunn Zoo in Vienna and the Aquazoo Düsseldorf ) was represented in the follow-up program " Animal Kumpel " at the same station. Repetitions are broadcast on ZDFneo .
Events
In June 2018 and '19 the Galactic Day took place, an event in which visitors presented themselves as science fiction characters e.g. B. Dress up from Star Wars ( Cosplay ) and organize a parade through the zoo. Other events include school holidays, adult night safaris, animal seminars, and themed weekend and guided tours such as the Australia weekend.
There are regular demonstrations of dolphins, sea lions and kolas. Some of the animals can be seen while they are being fed.
In August 2019, the Alzheimer Society Duisburg recognized the zoo as the first dementia-friendly zoo in North Rhine-Westphalia. Since then, specially designed tours for people with dementia have taken place on a regular basis , with the focus on the memory of the participants.
