From this story on the Oklahoma Department of Wildlife Conservation website:
_James Tucker of Ardmore pulled in a 192-pound, 1-ounce alligator gar Jan. 27 from the Red River in Love County, establishing a new state record. The record-breaking fish measured seven feet, seven and a half inches long and was an impressive three feet, three inches in girth. Tucker snagged the monstrous fish about 10 a.m. using a 65-pound test line. Tucker's fish broke the previous alligator gar record by more than six pounds. Sean Chatham, also from Ardmore, held the former record for a 184-pound, 3-ounce fish caught from the Red River in 2006. Alligator gar are truly unique fish and can be found in warm, sluggish rivers in the southeast quarter of the state. Alligator gar feed primarily on fish, but are known to eat ducks and other water birds.
_The second largest freshwater fish in North America, the alligator gar is second in size only to the white sturgeon. Reaching weights of up to 300 pounds, the alligator gar can stretch to lengths over nine feet. Historically, the alligator gar's home range included the Mississippi River and its tributaries from the lower reaches of the Ohio and the Missouri rivers southward to the Gulf of Mexico. Today the range is significantly smaller. The fish are primarily restricted to coastal rivers, with inland populations persisting not only in Oklahoma, but also in Florida, Georgia, Alabama, Tennessee, Arkansas, and Texas.
