Texas Natives

     I'm a recent import to Austin, Texas, and I am curious what types of 
     native fishes are natural to the local habitat, and where in central 
     Texas I may go to collect them.  I grew up in Fort Worth, Texas, and 
     spent my childhood knee deep in the local creeks collecting native 
     fishes, but alas its been over 25 years, and I couldn't identify them. 
     I've been gone along time, but am anxious to get back to collecting.
     Any help would be greatly appreciated,
     Thank You
