Commerson's Dolphins
09-05-2008
I've done some rough internet research on the history of this species in captivity. Most information I found is of the Sea World parks' animals.
In 1983, Sea World San Diego acquired several Commerson's Dolphins from South America and held them on display from 1984 to 1998. Recently a new 150,000 gallon tank was built near the new Atlantis wateride in the park and houses 1.2 dolphins. There have been 14 births at the San Diego park, the first occured in 1985. Sea World Ohio also housed several Commerson's Dolphins in an exhibit called Patagonia Passage with Magellanic Penguins (mixed species?). In 2000 several died from colotis. In 2001, the park was sold to Six Flags and 4 dolphins were moved to Sea World San Diego. In 2004, 1.0 Commerson's Dolphin, Yogi, arrived at the San Diego park from the Duisburg Zoo along with a Belgua whale. Last Year, 4.0 Commerson's Dolphins arrived at the new Aquatica park from Sea World San Diego. They are housed in a 240,000 gallon tank with enclosed water slides through the tank. (I had only heard previous reports of two dolphins in Aquatica, but the site below provides more information than any of my previous sources) Here is the current population makeup according to this website: Mammal Babble Sea World San Diego 1.0 Juan Wild Caught 1983 0.1 Betsy Wild Caught 1983 0.1 Ringer born July 2000 at Sea World, CA Aquatica, Orlando 1.0 Fabio born in captivity 1.0 Keebler born in captivity 1.0 Pepe Wild caught 1983 1.0 Ross born in captivity The website also did not mention Yogi, the Duisburg dolphin that arrived in 2004 or another dolphin, Rachel, that was born to Betsy in San Diego recently (last 5 years or so) according to a Sea World website. Also a link provided in the mixed-species exhibits thread provided another holder of Commerson's Dolphin from Japan, Toba Aquarium. Thanks Sun Wukong.

I have some pictures of them at Seaworld, and I have a book about them. I'll write some information up later for you okapikpr, I'm off to a flute lesson now!

@okapikpr: You're welcome. Besides Toba, Japan has several institutions keeping the species, like the Marinepia Matsushima Aquarium, the Shimonoseki Marine
Science Museum or the Notojima Aquarium. |

I've been on the lookout for any information on this species, since i heared at least some were going to move to aquatica. You got a lot further then me researching this animal species, i couldn't find anything on which (and how many) animals would be moved to aquatica.
The only thing i can add to your information is that Yogi, the animal that came from Duisburg did not integrate well with the existing group at seaworld, was kept alone for a few months and then died, being the oldest ever Commerson's in captivity. My usual source for marine-mammal related information is Whale Web (forum section), but recently it has been very quiet. I also couldn't find any information on there about Commerson's in captivity. If i find anything else i'll post it on here. |

Commerson's Dolphin's in Duisburg Zoo: kept: 1978 till 2004 No breeding - 1978 Import of 2.4 animals, of which 1.2 where destined to go to a Dutch dolphinarium (i don't know which one, at the time there were several in Holland); according to the yearreport first animals ever in captivity - 1979 1.4 died after just a few weeks, just 1.0 "Yogi" survived - 1980 Import, of 2.2.1, of which 0.2.1 died that same year; 2.0 "Pepe" and "Gaucho" survived - 1982 1.0 "Gaucho" dies - 1984 3.3 import; 2.3 died quickly, 1,0 "Busso" survived - 1989 1.0 "Pepe" dies - 1991 1.0 "Busso" dies - 2004 1.0 "Yogi" send to Sea World California, San Diego Information translated from the german zootierliste @ ZootierlisteHomepage Since Yogi was allready full-grown when captured, he was at least 26 years old, but as far as i remember he was estimated well in his 30's. I'll have a look around what i can find... |

I visited Duisburg in 1985 and they had three "jacobitas" as they called them, which must have been Busso, Pepe and Yogi. They were in a rather too-small pool with two belugas, and a short show was put on daily. At that time Duisburg had a big collection of marine mammals but I felt the accommodation was all on the small side, esp the two inia which were in a cupboard sized tank (I understand the surviving inia now has an excellent new home). The importation of 18 commerson's dolphins over 8 years with very high early mortality and no breeding is a rather sad statistic, I wonder if the higher mortality in the females was just by chance or if there was another factor. The zoo at that time generally had some very interesting and unusual species (eg the only red river hogs in Europe - how times have changed).

Sorry to make a digression:
@Pygathrix: Yes, back then Duisburg was one of Germany's top zoos in terms of zoological rarities (including Tasmanian Devils)-mostly due to the more or less controversial zoo director Wolfgang Gewalt(+). Most of the RRH's kept nowadays in European zoos have "Duisburgian" ancestors. I'm personally a great fan of the commerson dolphin, yet information about the status of the species in captivity, especially about the ones in Japan, is hard to come by.
