Well, ya learn something new every day around here!
Huh! I’d’ve thought they were more for hunting birds and other small game. Can a pellet penetrate water with enough strength to stun or kill a fish? 
The ones in the link look more like Dennis the Menace–types than the ones I was thinking of:
This is one mean-looking weapon! :eek: I see too there are other models that can fire lethal darts as well as pellets.
They’re for scattering bait on the water, not for shooting fish.
Aw, man, I much preferred believing it was for picking the carp off with rocks in the water.
Aha. That makes sense. Sort of.
Still, I bet you could use one of the dart-capable slingshots for spear fishing.
Speaking of which, I’m not sure this whole thread belongs in Cafe Society in the first place.
Well, it started with discussion of food items, and has largely featured them, but I’m not sure if that’s really the natural scope of the thread or not. Not being sure, I’ve let inertia be my guide so far, and left it here, but if you guys want to keep discussing the non-food things, I can go ahead and move it.
Well, it’s a discussion about language and language use, based on things we’ve read or heard through radio, television, and the movies, and through travel, cooking, and other personal experience. Doesn’t that make it appropriate for the Cafe?
Granted, we sometimes go off on tangents, but that happens in a lot of threads, doesn’t it?
The U.S. term for those, at least when I was younger, was “wrist rocket” (I now see that “Wrist-Rocket” is a registered trademark.)
And, apparently, there are no small number of fairly sophisticated (and, I’d guess, fairly powerful) “hunting slingshots” out there. Here’s one (on a web site for preppers) with a light, a laser sight, and a pistol-style grip. 
You forgot to mention that it’s TACTICAL. That’s worth a good additional $50 to the price, right there. Don’t waste your money on a slingshot with sights and a targeting laser if it’s not TACTICAL.
And also for maggot catty fights when the fish aren’t biting.
As a kid I used to gaze wistfully at the really expensive fancy slingshots for sale at Sky City*, but it has been a lifetime since that has even crossed my mind before these posts. (I had only a very simple model, possibly a Daisy.)
(*anyone else remember Sky City?)
You shoot cats with maggots?
You shoot each other with maggots, with your catty (catapult)
And the maggots are your bait?
Yes.
You bring a large amount of maggots with you, and you scatter them over the surface of the water to get the fish interested. However, if you get bored (and i was 15 when last I did this, and easily bored), you can use your catapult to fire them at your mates. It stings when you get hit, too.
You’re pulling our legs, right?
Nope, just never heard of such things. I haven’t been fishing since I was in grade [primary/elementary] school.
One last question: Do they sell maggots at bait shops, like worms?
I didn’t know about the slingshotting bait thing but, yes, you can buy maggots at bait and tackle shops. Worms, maggots, fathead, roaches … that sort of thing.
Red wigglers, the Cadillac of worms…
What does that make maggots? Yugos?
