Jigging for squid resembles ordinary vertical jigging, save for the peculiarities of squid jigs, which are hookless. They come in many types and in many different sizes. Some glow in the dark; some are solid metal; others are plastic-bodied and float or sink at a slow rate; a few have small integral lights. They all work, and they share a trait: rows of spiky pins built to take advantage of the feeding habits of squid, which seize prey with their tentacles and pull it toward their beaklike mouth. When a squid reaches for a jig, the angler will usually sense its weight. Pulling back drives the pins into the tentacles. From there the angler simply reels in steadily, being sure to give the squid no slack, which can allow the barbless pins to slip loose. The trick is to keep the squid moving smoothly and vertically, dragged along by the jig, and to continue the motion fluidly as it clears the water, via a gentle lift and swing that carries the squid into the air and onto the deck or, even better, to a waiting hand.
