Not really fill a carp up, it goes in one end, and straight through while continuing to eat.
Tigers are also not particularly good for the carp, the only nutrition they can get from them is the surface, once they are eaten, either chewed, crunched or whole, swallowed, they come out exactly as they go in. Obviously most tigers are crunched and broken in the pharyngeal teeth.
Tigers can be an addictive food, carp will eat almost nothing else if they are baited in large quantities, hence mixing up with hemp.
For one litre tub of hemp, I have a handful of tigers in there.
A single tiger on the hair, and a 5 tiger stringer works
