I'm afraid i have to ask a really obvious question as i'm new to fishing and am not doing very well so far. I've been float fishing and whenever i get a bite and the float shoots under the water i give the rod a good tug but i never seem to be able to catch the fish. What is it i'm met to do when the float starts bobbing in and out of the water? Is it right to give the line a pull or should i just leave the fish to bite down on the hook itself.
