Fishery

Crab is a delicacy popular not only in Russia, but also all over the world. People have been using crabmeat for various dishes, which is not surprising, as crabmeat is very good for health and tastes unforgettably.

Crab catching along Primorskiy Region coasts started in 1870s. However, the first tins were produced in 1908 by a plant near Gaydamak Bay. They used to catch crabs with fishing nets, but this method was not efficient, as small crabs got mixed up and died, that diminished the result of catching. Nowadays, there exist specialized fishery vessels, equipped by special catchers according to the kind of a sea inhabitant. Very often vessels are also equipped by technological constructions for product processing and producing.

It is impossible to predict places of crab concentration, as crabs move around their migration region during the year: they spend winter in deep waters and then come back to shallow waters. Experienced fish men rely on their knowing of areas and are guided by intuition and luck.

The most commonly used catcher represents a truncated cone with a top catching whole and an opening bottom. Its height is 0.7m, top diameter is 0.55m and bottom diameter is 1.5m, which makes catching faster and more effective. This method is suitable for Opilio and Kamchatskiy (King) crabs.

A testaceous animal is a predator, therefore a small feeding trough with fish (bait) is placed in a catcher and then it is set on a special tackle. There can be 20-200 such tackles simultaneously, that provides the most productive catching. The whole construction is put on a sea bottom where it is kept with anchors, and on a sea surface identification buoys are left. The procedure takes no more than 10 minutes.

Traps stay in the sea for two days at most, then it is necessary to take them out, as the bait loses quality and does not involve crabs any more. They are lifted with a winch or a special automatic crane.

There are some versions of the further actions: 1. If a vessel is equipped by special holds with the stipulated circulation of marine waters, alive crabs are placed there and delivered to the coast. 2. If a vessel is equipped by a system of clearing and processing of separate carb parts, an immediate processing, washing and freezing of production take place.

In any case, crabs are sorted right after catching. They are put on a big sorting table and selection begins: one rule is always followed - it is necessary to support a population, therefore females and small crabs are allowed to return to the sea for reproduction. A special plate on an internal side of an armour helps to distinguish a female, where caviar is kept, and suitable mails should be not less than 13sm in diameter, all the rest come back to their inhabitancy to grow and get stronger, so that crab-catchers could catch them again next year. The largest sample of Kamchatskiy Crab can reach 23sm on width of an armour and weight up to 7 kg (the Japanese call this type "Royal Crab").
