Did you get a load of the negative comments at the bottom? Wow. Looks like there's definitely a need for aquaculture to lift its public image up somewhat.

Yes and so totally ignorant it's appalling. Like the guy that thinks they are going to invade the Great Lakes. If he knew anything at all about what he was talking about he would know they would be toast once the water dropped to 50 F. Furthermore how in the world do fish make it out of fish tanks in a building to the Great Lakes? What an idiot.

Yeah its amazing really how people work. If you don't give them enough information about something chopped up into palatable chunks. Then they just start making it up using the ideas from the most paranoid of citizens as a foundation. At the end of the day its the responsibility of the industry to educate them if they want their market to continue expanding.

Hi Cecil,

While your point about Tilapia and the Great Lakes is valid from a temperature perspective, I question........

The answer is......the same way that tilapia made it into the river systems in Far North Queensland and the same way that European Carp made it into the rest of Australia's river systems......and the same way that the Signal crayfish got into British waterways, etc. etc. etc..........people put them there.

It is theoretically possible that in the great lakes there would be thermoclines that would provide the minimum temperature for tilapia survival. They would probably have to migrate to the depths during the winter.

There is a lake in texas , Fairfield lake, where tilapia and red drum overwinter at the heat exchanger of a large powerplant. If any power plants dumped heat there in the Great Lakes, this would provide a haven for warm water fish.

Interesting point. I hadn't even considered the possibility that micro-climates might be created for potentially invasive species by power stations and the like.

Doesn't the water in a lake bottom stay at 4 C ... And hence the Tilapia couldn't survive in the depths of a lake?...Though being beside a heat exchanger...I can see them enjoying it....

Not trying to make excuses, but here in this country our news media is quite negative and cynical as that is what sells -- especially the cable news networks. It's really hard to counter them, and what's really scary is they no longer just report the news, they do a lot of editorializing and actually skew the news along with all the pundits they have now.

I see your point and we do have warm water discharges in the Great Lakes but warm in the winter around them here in the Great lakes is a relative term. Not sure if there is even much 50 F. water when it hits that cold winter Great Lakes water. I do know the trout and salmon congregate around the discharges so it can't be that warm.

They may be looking for the tilapia.
