How Much Do You Know About Squid Fishing?
Squid, as a delicious ingredient that ordinary people like to eat, often appears on our dining tables. It is deeply loved by people because of its delicious taste and tender texture.
Every time you eat squid, do you wonder how squid are caught in batches from the sea in this era of industrialization?
We can all see that fishing boats will turn on rows of high-power light bulbs and use the phototaxis of squid to catch fish in a way similar to "moths flying into the flame".
First, the fishing boat will drive to the sea areas where squid are abundant and have already surveyed them, and then rely on radar and sonar to precisely locate them.
The underwater fish gathering light is the most important fishing aid equipment in light squid fishing operations. It has a wide trapping range and penetrates deep water layers. It can not only lure deep squid to shallower water layers for operations at night, but also Large squid can also be caught during the day by congregating in deeper water.
Squid mainly live near the offshore continental shelf. Fishing is usually done at night in the dark. Fishing boats will first put out underwater lights to lure the squid over, and then gradually lower the underwater lights upwards.
Then the fishing boat will turn on rows of fish-gathering lights. After the squids gather around the boat, it will turn off the headlights and change small bulbs to attract the fish to a fixed area more concentratedly.
Next comes the highlight – the fluorescent squid bait hook with a hook! Dozens of squid hooks are connected in series on a fishing line at intervals, like traps densely arranged under the water. The squid will think that these are glowing food, and naturally spread out its tentacles to hug them upwards, and then they will be hooked and unable to break free.
When the squid on the hook turns in the direction of the roller, it is like riding a roller coaster without a safety belt, and it automatically unhooks and is thrown to the net platform. The editor has to admire the wisdom of mankind! There is no need for manual decoupling, and the automatic operation is perfectly realized.
