Why cant this be used to do aquaculture?

It is a 336-mile long system of aqueducts called the Central Arizona Project.   I don't see why its not used to do aquaculture of various sorts. 
Farmed shrimp out here was great till the Asian imports got dirt cheap.  Now they have changed gears to grow algae for biofuels.
Could that be done here?

 The best solution would be to set up shop beside the aquaduct.  Using a Recirculating Aquaculture System (RAS), you could draw water during peak times.  A RAS allows the operator to manipulate water chemistry to the optimum grow parameters of the species they wish to culture.  The operator would also be able to manipulate the water to remove all the pollutants before it reentered the aquaduct (escapees would also be eliminated).
And of course I'm in the middle of a big move so all my books are packed up.  Lets see (goolge search), a yes, here we are.   http://www.freshwaterinstitute.org (copy and paste) These are the folks that are the leading researchers in North America on RAS.  
Well I'll guess because people don't want fish crap in their drinking water ?
Well yes, of course they do, but use a bit of psychology, explicitly adding extra fish is BOUND to get someone het up about it.

The whole point of aquaponics is the plants clean the water that the fish swim in, but since the system is going to seriously increase transpiration losses from the system, its not going to be very popular...

 like fish don't poop in water anyway?

There are tons of Carp in this water.
If, as Pagan says, CAP is barely functional now, adding a massive transpiration loss from a lot of plants in a very dry climate seems like a bad idea to me.

"Natural" (weird term for an invasive species) levels of fish are entirely different than penned aquaculture and the volume of waste that it produces.
It's to the point, gets my vote.

In addition to the pollution concerns others have mentioned, I'm pretty sure that those canals aren't kept full all the time.  Seems to me that sometimes you see this one full, sometimes that one. 

Any aquaculture project going on in them would therefore have to be able to deal with the on again off again nature of the water levels, or be able to move from one canal to another.

Or am I just imagining that they keep moving which ones are full and which empty?

Hmmm, I suppose you could float an aquaponics barge on the aqueduct.  You'd have to figure out how to get nutrients to the plants, in a way that wouldn't pollute the water, though.

Nice!

Since the CAP is BARELY functional (by that I mean, it transports water as designed but has so many maintenance problems that it could utterly fail at any moment.  The water lost to evaporation alone is appalling!),  I doubt it could handle any additional activity without serious problems.  You have a nice idea but the CAP isn't efficient enough.  IMHO

I suspect that would conflict with the other purposes of the aquaduct.
