Guadalupe bass
The Guadalupe bass (''Micropterus treculii'') is a rare species of fish endemic to the U.S. state of Texas, where it also is the official state fish. It is restricted to creeks and rivers (including the Guadalupe River, hence the name Guadalupe bass), and was formerly listed as vulnerable, but IUCN currently considers the data insufficient to determine its status.〔 Today, most fly fishermen and anglers practice catch-and-release techniques to improve fish populations. The Guadalupe bass is often difficult to distinguish from the smallmouth bass or spotted bass, and the first is known to hybridize.
== Description and range ==
Guadalupe bass, like most black bass, are lime to olive green in color, this particular species being lighter in shade usually in river specimens. They have a lateral line covered in mostly separate diamond shaped or circular spots, which with age fades from black to olive. There are also many smaller diamond marks scattered on the back which are less distinguished than the ones on the lateral line.
Its physical traits are very similar to the spotted bass (i.e. small mouth that doesn't extend past the eye, sleek figure, etc.) with one exception: the green coloring tends to extend lower on the body past the lateral line than their cousins. So far the record is 3.71 lbs (3 lbs 11.360 oz.), caught by Dr. Bryan Townsend of Austin in 2014.
The fish is only found in Edward's Plateau in central Texas. Its main habitats are the San Marcos, Colorado, Llano, and Guadalupe rivers. They can also be found in run-off creeks such as Barton Creek, Onion Creek, San Gabriel river, and The Comal river. The species has also been farm raised and stocked in the Llano river.
