James,
I posted it in an earlier note on this thread:
"here's the url

For information about the cormorant permit, including applications, contact TPWD Wildlife Permitting, 4200 Smith School Rd., Austin, TX 78744 or call (512) 389-4491.
The grass carp permit is linked to the TPW home page, as I remember.
The grass carp won't help your algae problem. The Tilapia will, but you have to give them time to work at it. Depending on how many you stock and how bad your problem is, it may take longer than you wish.
If you have a real bad case you may want to try some Cutrine Plus and then follow-up with the Tilapia for ongoing control. That is what I did.
See several other posts on the use of Cutrine Plus.
