Calgary zoo rays die due to human error
"we didn't have any expertise in aquariums or fish"
From the Calgary sun lack of dissolved oxygen killed rays.

Really?
It took that long to figure that out?

You would think before they went to the trouble to set up the aquarium, they would have hired an expert to overlook the entire process. Somebody really dropped the ball on that one.

It says that they used a system that was reffered to them by someone.
Unless that someone was the massive aquariums in the states or Vancouver even I would have been doing some extra research. Calgary zoo needs to buck up in my opinion. I still love taking my godson there, but now he asks where the rays are and where the baby elephant is. This kid is Two and he knows something isn't right

So is it one of the maintenance guys in Calgary? I don't think the zoo would name names.

summary: "The answer is 99.9% sure, we believe the dissolved oxygen was too low -- the life-support system was not designed to provide enough dissolved oxygen," said Lanthier. - "We didn't have any expertise in aquarium and fish, so we partnered with a reputable designer of life-support systems, one that came with a recommendation, and that's what we implemented," said Lanthier. While the system seemed fine for the first few months, Lanthier said the oxygen wasn't keeping up -- and when staff tried to save the rays, they altered the evidence. Keepers rushed to move the rays to another tank when the first signs of distress were noted, and in disturbing the water, they mixed in enough oxygen to make tests useless.

Someone somewhere dropped the ball on building and designing that enclosure.
Not the first time a zoo has killed aquarium life, a zoo in Indiana not long ago killed most of their sharks by over dosing ozone.

The question that needs to be asked now then:
Since the exhibit has re-opened (albeit without touching/feeding) have they rectified the design issues, or at least bought a profilux
