Calgary zoo rays die due to human error

[awa1979]

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

Although highly unprofessional, it's cases like this where I think about all the livestock that dies daily in shipping and in the hands of amateur (and experienced) and "experimental" aquarists.

+1, though a zoo should know better.

This is way different then that. A zoo charges for addmission and is expected to know at least something of the species they keep

My guess is a mag 3 pump with a rena air pump and one of those circular air stones.

Not to question the big wigs, but that is a relatively shallow tank with a huge amount of surface area. Even if there was no water movement does low O2 make sense?

Unless bacteria started using all the O2 (which would be noticed by green water) this does not seem possible.

You could probably shut off all the pumps and still have enough O2.

What do you guys think?
