HK received five sturgeons in celebrations of the Olympics, but three died and the two others are not faring well, and are to be returned to China. The five sturgeons were in the care of Hong Kong Ocean Park. Beijing even presented another five to HK after an apology from HK's leader. I've been to Ocean Park, the aquarium is a nice change from the humid outdoors of HK's summer time. It's a pity that care in HK was not enough to keep some of the precious breed alive. Maybe I would get a glimpse next time I'm in HK.
