    Notes: A marked diversity in the durations of river and sea existence and the frequency in spawning is shown in the samples of Atlantic salmon females, which were collected over six years. The data are presented on the size and weight of eggs and their dependence on age, and size of females and the time spent at sea. A correlation was established between the size of eggs of embryos and alevins.

    Notes: This study describes peculiarities of sperm production by anadromous and precocious parr Atlantic salmon. It was possible to obtain 15 sperm samples with total volume of 130 cm3 from anadromous males at the peak of the spawning run. Changes in the sperm characteristics with the increase of the sea-life age and weight of anadromous males are shown. Such changes are also shown throughout the spawning period. The properties of parr spermatazoa were investigated and it is suggested that these spermatozoa are suitable for insemination.

    Notes: Abstract. The results of population genetics studies associated with the problem of the restoration of Atlantic salmon, Salmo salar L., in Russia are presented. The peculiarities of using donor material for artificial population formation when the native gene pool has been lost are discussed. Genetic polymorphism in 19 salmon populations from different areas (within Russia) were investigated and analysed. Intrapopulation genetic differences of the Pechora River Atlantic salmon are shown. The role of monitoring in salmon culture is discussed and the results of an ecologo-genetic evaluation of natural and artificial salmon populations are presented.

    Notes: Data are presented on the current geographic distribution of Atlantic salmon, Salmo salar L., in freshwater bodies of Europe. They dwell in 14 hydrological systems, including basins of U lakes and three rivers. Nine of the lakes (Ladoga, Onega, Kuito and others) arc located in Russia, one in Finland (Saimaa) and one in Sweden (Vänern). All the rivers inhabited by freshwater salmon flow within Norwegian borders. Most of the lakes and rivers have good connection with the Baltic, White or Norwegian Seas. Over the past 20 years the freshwater salmon stock in Lake Imandra (the Kola Peninsula) has completely disappeared as a result of heavy human impact. The situation with such non-migratory salmon, which used to be important to fishing and trade, is also critical in all other water bodies. It is necessary, therefore, to elaborate effective measures for protecting and restoring freshwater salmon in the lakes and rivers of Europe.

    Notes: Atlantic salmon are caught in the coastal waters of the Baltic, Barents and White seas, in their river basins and in the lakes of Russia. About 1.5–2.0 × 103 tonnes of salmon were caught annually in these regions during the late 19th and early 20th centuries. Overfishing, dam construction and pollution of biotopes have resulted in habitat loss in the Gulf of Finland coastal waters and in the rivers and lakes of Russian Karelia. In the Arkhangelsk region, salmon yield has decreased by a factor of 3.5 when compared to data from the 1930–40s. The salmon harvest from the Kola Peninsula appears to have remained the most steady while, for the past decade, the Pechora and Varzuga rivers have yielded more than 50–60 % of the total Russian salmon catch. This crisis in restocking shows an urgent need for the rapid development of a federal programme to conserve the Atlantic salmon genetic resources within the region.

    Notes: From data on interpopulation genetic structure of the Atlantic salmon from the rivers of the Barents, White and Baltic Sea basins on U.S.S.R. territory, it is suggested that salmon colonized the Onega and Pechora River basins from the Baltic drainage as the last ice-sheet receded, and that the Kola Peninsula rivers were colonized separately from the Barents Sea area.

    Notes: In the Varzuga River (Kola Peninsula), juvenile Atlantic salmon occur at a high mean density of 1·1 individuals per m2, with a relatively low growth rate, reaching c. 8 g at age 3. They migrate to sea at ages 2–4 before they are fully silvered. Mortality is not high and the fish forage in the estuary where they grow fast and acclimate to the pelagic and high salinity habitat.

    Notes: The results of rearing salmon smolts, using warm water in winter time, are presented. Fishes weighing 25–50 g were released in spring time at the age of about 1 year, while smaller fishes were left to grow in ponds for release at age 2 years. As a result of warm-water wintering of fingerlings, the yield to the fishery was at least doubled, while there was no decrease in fish size, nor in gamete quality. Three thousand to 5000 spawners entered the Narova River (Baltic Sea) per annum and the trend is to exceed these totals.
