The following are copy and pasted from WORD documents you can download at:
http://www.tpwd.state.tx.us/business/permits/land/wildlife/"Fish farms or aquaculture facilities are not eligible for a state-issued Nuisance Double-crested Cormorant Control Permit. Aquaculture facilities may apply for a federal depredation permit from the U.S. Fish & Wildlife Service Migratory Bird Office at 505-248-7882."
"Except as allowed under Parks and Wildlife Code, §43.154(d), and §43.021-§43.030, no person may attempt to take Double-crested Cormorants unless that person possesses a valid Nuisance Double-crested Cormorant Control Permit issued by the department and a valid Texas Hunting License."
"A Nuisance Double-crested Cormorant Control Permit is issued for only one tract of land. A separate permit is needed for each property owned by the same landowner if the land is non-contiguous."
"The following are the only approved methods for the take of Double-crested Cormorants under a state Nuisance Double-crested Cormorant Control Permit: firearms (shotguns must utilize non-toxic shot only), cervical dislocation and CO2 asphyxiation."
"This permit is restricted to the control of Double-crested Cormorants and IS NOT a public hunting permit."
For more information, please contact the Texas Parks and Wildlife Department at 512-389-4481.
