This post was really interesting because I am a bowfisherman and found it really interesting that I know a lot of the guys in those pictures. You do realize that these are not MonsterKeepers pictures and I would suggest that you contact those guys/websites and get permission to use their pictures before you put your watermark on them. Most bowfishermen are cool about it as long as you ask first.
I really thought it was cool that some of you are defending bowfishing and seem to understand our passion. I agree that sportsmen are the #1 conservationists.
With bowfishing the gator gar is the king and is highly sought after, and yes, they are eaten and are pretty good. I prefer mine fried but then I like my tilapia fried too. Bowfishing is not as easy as you might think...you are shooting a bow with no sights, dealing with water refraction, moving fish (generally pretty fast), and in my case from a moving boat. I sometimes wonder how I hit anything!
The thing to remember is not to confuse gar with gator gar. Shortnose gar are like mosquitos down here is South East Texas. They are just about everywhere and they grow like crazy. I think the one report I read about them growing from an egg to 2 ft in a year is pretty accurate, depending on the food source. I kept a shortnose for about 8 months and it outgrew the tank quickly so I released him in a buddy's 1 acre pond. They are definitely fast growers and if you saw the very high numbers of them that we see at times you would be amazed.
Alligator gar do tend to grow at a slower rate than their cousins but then again I do not believe every report I have read on them either. Mainly because as with most wild animals and fish the food source and amount of food source makes all the difference. If a gator gar can barely eat enough to survive it is going to grow slower than one who has plenty to eat. Also try to remember that habitat loss is the biggest reason why you do not see gator gar is certain parts of the US that used to be. Build a dam and the river does not flood as often and gator gar love flooded waters.
