The Texas Parks and Wildlife Department is proposing changes to regulations regarding harmful or potentially harmful fish, shellfish and aquatic plants.

The proposed rules will be published in the Texas Register no later than Friday, Oct. 2. At that time, comments on the changes can be provided on the TPWD public comment page until Monday, Nov. 9. The TPW Commission will take public comment on the proposed changes at their meeting on Tuesday, Nov. 10 in Austin.
