Are squid caught on purpose or is it a by-product of fishing?
Squids are molluscs. When cooked, they are an excellent dietary product -
it is a protein rich in phosphorus, vitamins and amino acids.
Squid has been used in cooking for centuries. Everything is edible in it, except for the eyes and beak, even the ink is used to make seasonings. Squids are especially popular among residents of Italy, Japan and Korea.
In Russia, squid has become popular since Soviet times. Then our country was the world leader in the extraction and processing of squid. I remember at that time meat was not always possible to buy, and fish and squid were always on the shelves of shops and markets, both frozen and in the form of canned food.
For example, in 1985, our fishermen in the fishing area near the Kuril Islands and in the western part of the Bering Sea caught about 60 thousand tons of Commander squid with bottom trawls.
Now, no more than 20 thousand tons per year are mined, although the reserves in our seas are such that it is possible to extract up to 100 thousand tons per year without prejudice to the population. And with such reserves, Russia imports squid from China, Chile, Peru and other countries!
In addition to the Commander squid, the more valuable Pacific squid can be hunted in our seas. When the water temperature in the Sea of Japan drops, the Pacific squid begins feeding migration towards our southern Primorsky coast, approaches the Amur and Ussuri bays in huge schools. Itself swims into the hands, just catch it.
But our fishermen do not want to bother with Pacific squid, they are more interested in catching valuable export types of seafood, such as crabs, shrimps, scallops, sea urchins, etc.
On the other hand, how will they catch this squid? It feeds and migrates in the surface layers of the water, and not at the bottom, like the commander. You can't take it with a bottom trawl, but we have a jigger schooner once or twice.
But our neighbors do not yawn - they take quotas and fish in our waters as much as the schooners fit. They have everything for fishing: schooners, jiggers, powerful lamps to attract squid, tanks for cooling and storage, and most importantly - the desire and support of the state.
In the photo - a schooner for catching squid. The glass bulbs in the middle are powerful lighting bulbs. Along the sides - jig installations. They consist of an electric motor for driving a diamond-shaped drum, from which a synthetic fishing line with brightly colored baubles - jiggers, at the ends of which there are two rows of sharp beardless hooks - is reeled up and onto which, when the catch is lifted. A sinker at the end of the line.
Round spools are line guides. They are installed on brackets above the sides in a working position.
Pacific squid is caught at night. The echo sounder is used to locate the school.
The line with jigger blons is uneven, twitching (dancing - jig), because. the drum is rhombic, sinks into the depth.
Squids rush onto the flickering jiggers lit by lamps, get caught on the hook, then the fishing line is wound on the drum, passing the guide reel, the squids are unhooked from the hook and fall into the chute under the drum, through which running water is washed into a special tank.
The whole process is automated, the fishermen only control the process, they are engaged in sorting, placing in containers for cooling in the hold.
This is how they produce commercial squid fishing... It is also caught with bottom trawls, twin trawls (this is when a trawl is between two vessels), as well as gill nets.
Squids are caught on purpose and sometimes fish is a by-product in a trawl or net.
Of course, squid fishing is a commercial one, some fishing companies specialize precisely in the extraction of this cephalopod mollusk. It is caught mainly in the southern seas of Asian countries, such as China, Japan, Vietnam, the Philippines, as well as near Peru, the Falkland Islands and on the shelf of Patagonia. Our fishery is quite widespread in the Sea of Okhotsk.
Overfishing, as such, does not threaten this species of marine life in principle. The fact is that these mollusks very quickly reach sexual maturity and immediately begin to reproduce. And they live only one or two years. So the number of caught squid is replenished almost immediately by young growth.
