There are more then 3 zoos in Europe which keeps Malayan tigers.
In Germany: Halle (1,2 breeding tigers) TP Berlin (1,1 brother and sister from Halle), Zoo Berlin (1,1 non-breeding), Dortmund (0,2 sisters from Halle)
Zoo Prag (1,2 brother and sisters from Halle)
Zoo Usti (0,1 from Halle, and I think 1,0 importet from Asien)
Halle has 2,0 offsprings who has to leave Halle.
It is very important to get new tigers from Asian for a succesful genetic pool.
