Stingrays are a tricky species

Almost a year ago, nearly all the stringrays at a Calgary Zoo exhibit died by what was now being called a lack of dissolved oxygen.  At the time it was big news.  Even the police were called in to determine if it was sabotage.

Everyone one of us has lost livestock and most good honest aquarists don’t take it lightly.  We act as quickly as possible to minimize the deaths.  We take the loss hard and make updates to our system so that it doesn’t happen again.  Sometimes we buy things that shouldn’t go in our tanks and we learn a hard lesson.  There’s some hard lessons for aquarists to take from the Calgary Zoo.

However, this incident smacks of arrogance and now all that’s left is the finger pointing.  To me, it seems like everyone from the supplier to the Calagary Zoo staff are responsible.  Let’s take a look:

“Because this was an established zoo, we assumed there was a certain level of expertise that comes with handling these types of animals,”said Marty Tanner, president of Florida Marine Aquaculture.

“We had to assume . . . that there was a certain level of expertise with the life-support system and with their personnel, their veterinarians. We supply these animals to a lot of zoos and aquariums in the United States and overseas;we’ve never had this issue before,” said Tanner.

So, the supplier, Florida Marine Aquaculture isn’t claiming responsibility.  They’re content assuming and counting the money from the transaction.  I don’t know, but I’m guessing 41 stingrays added nicely to his bottom line last year.

It’s time for a change in the climate of the hobby.  Suppliers, and for most of us that’s our local fish stores, need to start being responsible for what they’re selling to people.  There needs to be accountability for the lives that we’re taking responsibility.  Stores are too comfortable selling anything to anybody with a credit card.

You want to recreate a replica of the aquarium from Finding Nemo?  Well, hold on there.  There’s a few things you should know about.

These comments from the Zoo president make me think that more deaths are coming:

The Calgary Zoo, clarifying Tuesday that a lack of dissolved oxygen likely killed the rays last year, said it isn’t planning on changing its practices and is confident it can care for animals by referring to outside advice.

Zoo president Clement Lanthier and Cathy Gaviller, the zoo’s director of conservation, education and research, told reporters that they knew as early as November that low levels of dissolved oxygen were probably the cause of death.

“I think we need to be very frank here. Our main expertise is not in fish at the Calgary Zoo. This is something that we want to expand. We have a responsibility to connect Calgarians not only to land animals but also what is going on in the ocean. We will continue to go there,” Lanthier said.

There are some good reefers out in Calgary.  I hope the Zoo speaks to them.
