Valeriy Zyuganov graduated from the Faculty of Biology, Moscow State University in 1977.
Since 1977 Valeriy Zyuganov has been a researcher (graduate employee) at the Koltzov institute of developmental biology of Russian Academy of Sciences in (Moscow).
Since 1980, he has been a candidate of biological sciences. At Moscow State University, he presented a thesis on the topic: - "Mechanisms of formation of complex of Gasterosteus aculeatus sensu lato". After presenting his doctoral dissertation, he was appointed a junior researcher in the Koltzov institute of developmental biology of Russian Academy of Sciences in Moscow.
Since 1985, he has been a research fellow in the Koltzov institute of developmental biology of Russian Academy of Sciences in Moscow.
In 1989 he received the commission of chief scientific worker.
In 1994, Valeriy Zyuganov became a Doctor of Biological Sciences. At the St. Petersburg State University in Saint Petersburg, his doctoral thesis and scientific paper are on the specialty 03.00.10 — ichthyology on the theme: - " The family of stickleback (Gasterosteidae) in the world's fauna."
Since 2005, Valery Zyuganov is the head of the group of ecology and biological systems evolution in the Koltzov institute of developmental biology of Russian Academy of Sciences in Moscow.
In the late 1980s and early 1990s, V.V. Zyuganov formulated the concept of freshwater pearl mussel–—Atlantic salmon symbiosis. [1] [2] [3] [4]
In the 1990s, V.V. Zyuganov and colleagues developed a number of biotechnologies for breeding rare and endangered species of freshwater mussels of a genus of Margaritifera, which are included in the IUCN Red List of the USSR. These inventions are protected inventor's certificates. [5] [6]
In the 1990s, V.V. Zyuganov, in the framework of the concept: - a freshwater pearl mussel - Atlantic salmon symbiosis, put forward the parasite-gooder hypothesis, which prolongs the life-span of the host. This hypothesis is supported by a number of known researchers. The debate has moved beyond the scientific community of Russia. The Zyuganov hypothesis was discussed at international conferences and was cited in scholarly journals and monographs of known researchers. [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] The tone of the debate was relented after having been discovered similar facts of a life extension of a host by means of parasite in pairs: - parasitic worms - fish and crustacean - fish . [17] [18] [19] For the Zyuganov hypothesis were appeared credible proponents [18] [19] [20] and opponents [21]
V.V. Zyuganov received worldwide reputation after he discovered the fact of a negligible senescence and determined the maximum lifespan (210–250 years) of the freshwater pearl mussel (Margaritifera margaritifera). [15] [22] The data of V.V. Zyuganov have been confirmed by the Finnish malacologists [23] and gained general acceptance. [24] In general, the V.V. Zyuganov is the author of 120 scientific papers, 6 monographs, and patents.
Zyuganov is known as the author of antineoplastic drugs "Elixir Arctic +" and as the author of publications in popular scientific literature about human aging.
Zyuganov is the president of the international "Society Conservation Margaritiferidae" (SCM). [25] A new society was formed at the Twelfth International Malacological Congress in Vigo, Spain in September 1995 to promote the conservation and management of margaritiferid species around the world. The freshwater pearlshells of the family Margaritiferidae include 25 nominal genera that inhabit rivers of North America and Eurasia, with some species and many populations in imminent danger of extinction or extirpation, respectively. The SCM was formed by a multinational cadre of scientists for the purpose of coordinating international efforts for research, management, and the protection of habitats critical to these species. One of the long-term goals of SCM is to create an international monograph on the systematics, distribution, ecology, and status of margaritiferids globally.
Since 1992, V.V. Zyuganov is supervisor the Salmon wildlife preserve of Varzuga.
V.V. Zyuganov was repeatedly elected a member and chairman of the Far East of the Ministry of Natural Resources of Russia, which examines allowable catches of Pacific salmon.
Zyuganov studied the evolution of marine and freshwater fauna, ecological and physiological basis of animal and human longevity. He was the supervisor and member of environmental projects in Russia, Germany, Spain, France, Britain, Norway and Sweden. Zyuganov investigated non-aging aquatic organisms in the laboratory and in 70 expeditions in Russia, the United States, 20 countries in Europe, Africa, and Southeast Asia on the coast of the Pacific and Indian oceans. Recently, Zyuganov has focused on studying the negligible senescence phenomenon. He shows himself as an apologist of the astrocytic hypothesis of aging of mammals in polemics with opponents.

Just like the shell of a mollusk, a pearl is composed of calcium carbonate in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable.
The River Tay is the longest river in Scotland and the seventh-longest in Great Britain. The Tay originates in western Scotland on the slopes of Ben Lui, then flows easterly across the Highlands, through Loch Dochart, Loch Iubhair and Loch Tay, then continues east through Strathtay, in the centre of Scotland, then southeasterly through Perth, where it becomes tidal, to its mouth at the Firth of Tay, south of Dundee. It is the largest river in the United Kingdom by measured discharge. Its catchment is approximately 2,000 square miles, the Tweed's is 1,500 sq mi (3,900 km2) and the Spey's is 1,097 sq mi (2,840 km2).
Bivalvia or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidia, specialised organs for feeding and breathing.
Pinctada is a genus of saltwater oysters, marine bivalve mollusks in the family Pteriidae. These pearl oysters have a strong inner shell layer composed of nacre, also known as "mother of pearl".
The River Ehen is a river in Cumbria, England.
The freshwater pearl mussel is an endangered species of freshwater mussel, an aquatic bivalve mollusc in the family Margaritiferidae.
Margaritiferidae is a family of medium-sized freshwater mussels, aquatic bivalve molluscs in the order Unionida. It is the most threatened of all unionid families.
Sinanodonta woodiana, the Chinese pond mussel, Eastern Asiatic freshwater clam or swan-mussel, is a species of freshwater mussel, an aquatic bivalve mollusk, in the family Unionidae.
Unionida is a monophyletic order of freshwater mussels, aquatic bivalve molluscs. The order includes most of the larger freshwater mussels, including the freshwater pearl mussels. The most common families are the Unionidae and the Margaritiferidae. All have in common a larval stage that is temporarily parasitic on fish, nacreous shells, high in organic matter, that may crack upon drying out, and siphons too short to permit the animal to live deeply buried in sediment.
Margaritifera is a genus of freshwater mussels, aquatic bivalve molluscs in the family Margaritiferidae, the freshwater pearl mussels.
Cumberlandia monodonta is a freshwater mussel endemic to the United States. Currently, C. monodonta is listed as an endangered species by the U.S. Fish and Wildlife Service and the International Union for Conservation of Nature.
The oyster mussel is a rare species of freshwater mussel in the family Unionidae. This aquatic bivalve mollusk is native to the Cumberland and Tennessee River systems of Kentucky, Tennessee, Alabama, and Virginia in the United States. It has been extirpated from the states of Georgia and North Carolina. It is a federally listed endangered species of the United States.
Margaritifera auricularia is a species of European freshwater mussel, an aquatic bivalve mollusk in the family Margaritiferidae, the freshwater pearl mussels. Formerly found throughout western and central Europe, the species is now critically endangered and is one of the rarest invertebrates worldwide, being confined to a few rivers in Spain and France. M. auricularia is commonly known as Spengler's freshwater mussel in honour of Lorenz Spengler, who first described this species.
Margaritifera marrianae, the Alabama pearlshell, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Margaritiferidae, the freshwater pearl mussels.
Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (senescence), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age. There are many species where scientists have seen no increase in mortality after maturity. This may mean that the lifespan of the organism is so long that researchers' subjects have not yet lived up to the time when a measure of the species' longevity can be made. Turtles, for example, were once thought to lack senescence, but more extensive observations have found evidence of decreasing fitness with age.
Aquaculture is the farming of fish, shellfish or aquatic plants in either fresh or saltwater, or both. The farmed animals or plants are cared for under a controlled environment to ensure optimum growth, success and profit. When they have reached an appropriate size, they are harvested, processed, and shipped to markets to be sold. Aquaculture is practiced all over the world and is extremely popular in countries such as China, where population is high and fish is a staple part of their everyday diet.
The River Allow is a river in Ireland, flowing through County Limerick and County Cork.
Aquaculture in the United Kingdom is dominated by salmon farming, then by mussel production with trout being the third most important enterprise. Aquaculture in the United Kingdom represents a significant business for the UK, producing over 200,000 tonnes of fish whilst earning over £700 million in 2012 (€793 million).
The Nore pearl mussel is a critically endangered species of freshwater pearl mussel, an aquatic bivalve mollusc in the family Margaritiferidae.
