Well, I will try my best to give you a brief summary of manatees in Denmark. I am pretty sure that all of this information is correct but there may be a few mistakes in there.
History of manatees in Denmark
The first manatees ever to be kept in Denmark arrived in the newly built Oceanium exhibit in Odense ZOO in 2001. The species is West Indian manatee and the first individual to arrive was the female "Henriette", born in Nürnberg. In 2002 a further 2.2 manatees were imported from Guyana Zoo to Odense ZOO to join the female in the new exhibit bringing the number up to 2.3 manatees.
In 2003 the next manatee exhibit opened in the new South America Dome in Randers Tropical Zoo. The individuals moving in here were the female "Gaffa" (one of the imported females from Odense ZOO) and the male "Bertus", the last manatee to have lived in ARTIS Amsterdam, the Netherlands, were he was also born. These two manatees still live in Randers but have so far only managed to reproduce one stillborn young.
After a few years one of the male manatees in Odense ZOO sadly passed away, leaving 1.2 adult manatees, 1.1 from Guyana and 0.1 from Nürnberg. Over the following 10 years Odense ZOO has seen 3.3 healthy newborn manatees of which 1.2 have already been sent on to participate in the EEP (a male to Nürnberg and a female to Beauval in 2009 and a female to Genoa in 2013).
In case you are confused the total numbers for the two zoos in Denmark are
Odense ZOO: 3.3
Randers Tropical Zoo: 1.1
About the exhibits I will see what I can find sometime during this week
