Yes, a treble hook is more reliable, but not as packable.

The best way to catch fish, barring the use of poison, concussion grenade, or electricity, is a gill net.

They are quite illegal for sport or commercial fishing, because they work so well.
The military pilot survival gill nets with 1" openings on eBay are a little large for most freshwater fish, but the net is more than long enough to cross a creek so that everything, including turtles can be driven into one.
I have a gill net in my abandon ship bag, as well as in my plane.
