Bite detection on a beach

The description is about reading the signal. This is about not destroying it before it arrives, which is where most of the information is lost.

ROD ANGLE IS THE BIGGEST SINGLE LEVER AND IT IS A TRADE. HIGH — rod near vertical in a tripod — lifts line out of the water, removes most of the tide's pull on it, and gives the cleanest signal. It also puts the tip up where the wind gets it. LOW — rod horizontal or pointing down the beach — is almost immune to wind and buries the line in the tide, so everything is muted and a slack-line drop-back becomes invisible. On a still night, high. In a gale, low, and accept that you are now fishing for pull-downs only.

A TIP THAT IS TOO STIFF SEES NOTHING. The tip has to be soft enough to be moved by the fish you are expecting. A beachcaster tip rated for six ounces and a gale will not register a school whiting nibbling. If small fish are the target, the answer is a softer tip section or a lighter rod, not more concentration.

THE LINE, NOT THE ROD, IS THE SENSOR. Braid transmits a bite that mono absorbs, and on a long cast in deep water that difference is decisive. Mono's stretch is a genuine advantage in surf, where it damps the noise as well as the signal. This is a real choice and neither answer is general.

AT NIGHT. A starlight or a clip-on tip light is standard and it changes what you can see: a light shows movement well and shows the SHAPE of movement badly, because you are watching a point rather than a curve. Anglers who fish a lot at night tend to keep a hand on the line above the reel as well, because the line carries the sharp knocks the light will not show you.

AND FEEL THE LINE. Holding the rod, or resting two fingers on the line, gives you signals the tip never renders — the gritty rasp of a lead creeping over gravel, the soft progressive load of weed, the tap of a small fish. On many marks a held rod catches noticeably more than a rested one, and that is the reason.

Having read the signal, the second half of the skill is what to do about it, and the honest answer is that it depends on the rig you have chosen and on what is biting.

MOST SHORE RIGS ARE SELF-HOOKING AND MOST STRIKES ARE UNNECESSARY. A fish that moves off with a bait, against a lead that is gripped and a line that is tight, hooks itself. On that setup the sequence is: watch the knock develop, wait for it to become a steady pull or a slack-line, then wind down until you feel the fish and lift. Striking at the first rattle pulls the bait away from a fish that had not yet taken it, which is the commonest cause of a night of knocks and no fish.

WHEN WAITING IS WRONG. Fish that swallow deeply — and small fish generally — are hooked deeper the longer you leave them, which is a welfare cost and not a tactic. On rough ground a fish left to run reaches structure and is lost with the rig. And on a fine wire hook and a light bait, a fish that mouths the bait for a minute has usually stripped it.

THE TEST THAT SETTLES IT FOR YOUR MARK. Wind in. That is the whole method, and almost nobody does it. If you have had knocks and you retrieve to find the bait gone, you are being robbed and should be striking sooner or changing bait. If the bait is intact, whatever was knocking was not eating and there was nothing to strike at. If the bait is there but flattened, you have crabs. Three retrieves during a session teach more about the signals on that beach than an evening of theorising, and they cost you nothing because the bait needed refreshing anyway.

WHAT NOBODY TELLS BEGINNERS. Very large fish frequently produce the smallest signals. A big bass or a ray sitting on a bait can register as the tip going gently slack and staying there — because the fish has picked the bait up and moved towards the shore, which takes tension off the line rather than adding it. A slack-lining is not the absence of a bite. It is the bite most often ignored.
