MOVEMENTS FOR FISHING FOR CEPHALOPODS
A simple and effective movement consists of letting the lure sink down in the water until you feel a slight "toc", indicating that the jig is properly placed on the bottom. Then gently bring the lure back in. The latter will then "scrape along the bottom" to attract the squid that are nearby. If you do not feel any vibrations in your rod, it will be that your jig has stuck to the bottom. Slow down your movement in order to let down the lure again.
If you feel a weight settle on your lure, strike immediately. The movement must be sudden so that the cage attaches well to the cuttlefish.
If scraping the bottom doesn't work, you can try the technique called "bichi-bachi". Originally from Japan, this movement consists of letting the lure down to mid-water level, then tapping the rod energetically upwards (3-4 times) before a short pause. The touch usually comes during the pause.
You can alternate these two movements as much as you want until you find the most productive one. Cephalopoda fishing is not an exact science and the winning technique can vary from one day to another.
