Hatchery Operations (Real Media)


TPWD operates freshwater and saltwater hatcheries around the state. Personnel maintain complex hatchery facilities designed to study and breed fish for release in state waters.

SeaCenter Texas is an example of one of the department's three world-class hatchery facilities. Our webcast guest, Paul Silva, works at the GCCA/CPL hatchery in Corpus Christi. The Red Drum game fish is bred at our hatcheries and released to increase the population available for fishing.


Seining allows biologists to collect shallow water specimens for study.


Biologists take "creel surveys" -- they collect data on the fish that both commercial and recreational anglers catch. This data helps biologists determine the status of species and best management practices for coastal species and habitat.

Scientists study fish closely


DNA analysis helps scientists unlock the keys to the most successful species, and those in trouble.


Fish from the hatcheries are released in coastal bays and estuaries.

Using pit tags that can track fish


Tags are inserted into the fingerling (young) fish.


Fingerlings are moved to larger ponds to grow before being released into lakes or rivers.
