Project 940 "Lenok"
India class

Equipped with two deep submergence rescue vehicles (DSRV), the India class submarine was designed to locate submarines in distress and to rescue the distressed submarines crew. The India was fitted with medical facilities and decompression chambers that allow the submarine to treat several dozen individuals at a time. The DSRVs can dive to 500-1,000 meters and rescue crews by docking with the escape hatch of a submarine. India class submarines could also be used in salvage operations.

Lazurit designed the Poseidon class DSRVs used by the Russian Navy. Four operational and one experimental models were built. The DSRVs operate in pairs, generally carried onboard an India class submarine. They are capable of launch and recovery while the submarine is submerged. The normal navy procedure is for the crew of a downed submarine to escape by locking out at depths down to 120 m. Beyond this depth, to a maximum of 500 m, the DSRVs are used. The vehicles can carry twenty-four passengers and a crew of three.

Both units are no longer be operational, having been placed in reserve around 1990 and scrapped in 1995.

Lenok - Trout

The Lenok is sharp and fast predatory fish which reaches up to 5 kilograms. Lenok is a kind of salmon, which grows rather slowly. It weight usually makes 2-3 kg. Color is dark - brown or black with golden shade. The sides, back and tail fins are covered with fine round dark spots. Lenok never enters the sea. It inhabits in all the rivers, running into the Okhotsk and the Japanese seas. Lenok is a predatory kind of fish. Large species, can eat frogs and mice as well as the fine fish. It also feeds with large river bottom reptiles. Lenok is the object of amateur fishery. Lenok can be caught since spring till the late autumn. Knowing its pecularities and the good training and the properly chosen equipment usially guarantee sucessfull fishing.

Brachymystax lenok is a salmonid fish distributed throughout Siberia. The Asian endemic salmonid fish Brachymystax lenok occurs in all major Siberian river systems. Markakol lenok (Brachymystax lenok savinovi Mitrofanov) abound in Lake Markakol and rivers flowing into it as well as the only river flowing from it - the Kalzhir. In addition it is found in the neighbouring rivers- left tributaries of the Irtysh River: Kara-Kaba, Ak-Kaba, Kurchum and others. The Markakol lenok differs from ordinary Siberian lenok with its large size and weight but with only a small difference in the form of its body. Sharp- and blunt-snouted lenok are independent evolutionary lineages, with the majority of their variation distributed among major river basins.

Formerly one could catch a lenok weighing up to eight kilograms but presently not more than five kilograms. Ordinary length is 45-55 cm. Spawning period begins in the last ten days of May and ends in mid June for the majority and in July for some other lenoks. The most intensive fishing starts after the first autumn frosts, that is mid September to early October. Since Lake Markakol and the major rivers flowing into it are found in the Markakol sanctuary, the main place where the taking of lenok is legal, is the Kalgir River- from its mouth to the middle of the stream, along with the eastern part of the lake. The zone for amateur fishing has an area of 1,550 hectares. A lucky fisher can take 200 and more lenoks a day.

Manchurian Trout [Brachymystax lenok] has been widely introduced in cold waters for sports and aquaculture. Many are anadromous , spending part of their life at sea, but returning to freshwater where all species spawn in a gravel bed in rivers or streams ; most fish die after spawning. Small cycloid scales. Gill membranes reaching far forward, detached from isthmus. Axillary process on pelvics . Last three vertebrae directed upward. Highly valuable in sport and commercial fisheries. There is disagreement about the status of some species and genera. The family Salmonidae belongs to the Class Actinopterygii (ray-finned fishes ) and the Order Salmoniformes.
