"Galveston, oh Galveston.... I still hear your sea winds blowin...." (lyrics, Glen Campbell)
Ready for a great fishing trip? You'd be hard pressed to find a better fishing site than in Galveston, Texas, where you have two waters to choose from--the Gulf or the Bay.
Galveston is a barrier island off the coast of south Texas just down the road a piece from Houston. On the north side of the island is Galveston Bay; the south side faces the Gulf of Mexico. The Bay yields an abundance of speckled trout, red fish and flounder, but the Texas state record for the largest tarpon ever caught was set when a 220-pounder was pulled out of the Gulf. Anglers have a tough choice when it comes to deciding where to fish.
One reason fish is so plentiful in Galveston Bay is because it's an estuary, a body of water where saltwater and freshwater combine to make a nutrient-rich marine-life nursery. It's so plentiful that the EPA has declared this bay an estuary of national significance. 
Galveston Bay spans 600 square surface miles and is home to 162 species of fish. The “Big 3”, as they are affectionately known to Gulf Coast anglers, are redfish, specks and flounder.
