This one is about Alligator Gar.
Alligator Gar are one of the largest freshwater fishes. They live primarily in brackish water in the S. Texas area, although I think there are some in China. Warm, stagnant water is preferred. They have an air bladder, which most fish do, but theirs is special and is connected to their breathing gills. This allows them to gulp air for oxygen instead of getting it from the water. They are prehistoric type creatures, unchanged through time. Their range is shrinking, however, though the populations in Texas seem stable.
The bodies are mostly cartilage with very little bone. The big scales are often used in Native American jewelry, and in the past as tools- scrapers and even arrowheads. The flesh is white, firm, and quite tasty... one factoid: most fish sold as "fishsticks" comes from gar- either this species, or another. (which also lives this far north- the longnosed gar)
These fish are a high-adventure sport fish, or a nuisance, depending on your point of view. The guys below were bowfishing. If you can't imagine that, it involves searching for the fish, and actually shooting them with a bow, which is harder than you think. This is merely to get a hook in! These fish are covered with big plate scales for protection. Anyway, once the arrow, attatched to your "fishing line"- generally more like a rope or small steel cable- you have to battle the darn fish on a rod. Crazy stuff. I wish they wouldn't bowhunt them, instead get them to bite like regular fishing.
Longnose gar:
haha.. that's not me or anyone I know...
Personally it's my goal to catch one. They are here in the lake I fish, but the best time to fish them here is in late spring- they are in shallow water then.
