The official statistics data of domestic catches do not allow to form appropriate estimate about the actual state of stocks and population dynamics of Russian Pacific salmon in the 20th – early 21st centuries, because a significant fishing load was provided by Japanese fishermen for a long time. During this period the stocks were on the rise twice (from 1929 till 1960 and from 2004 till present time) and once they were in a depressed state (1961–2003). Apparently, the maximum abundance values during the rise periods were approximately at the same level. The duration of high and low abundance periods is approximately similar. The full cycle of changes in was 65–75 years. The current period of the Russian Pacific salmon high abundance, according to the rhythm of previous periods, may last until the early 2030s. The minimum recorded catches during this period of time will be at least 250 thousand tons and the maximum will be in the range of 500–600 thousand tons.

The article describes fermentation process of the Baikal omul with the bacterial concentrate containing Lactobacillus sakei LSK-104. pH and microbiological analyses were used as indicators of biochemical activity of lactic acid bacteria. As found, during fermentation of omul, pH of the muscle tissue in the experimental sample decreased faster and reached 5.05 at 14 days of fermentation, while in the control sample the pH value was 6.28. It can be explained by the formation of organic acids during the fermentation with lactic acid bacteria L. sakei LSK-104. In this case, the number of viable cells reacheed a maximum value of 1011 CFU/g. The lactic acid fermentation process in brine proceeded more intensively than in the muscle tissue. The data obtained in this study expand our understanding of the adaptive mechanisms that ensure survival of L. sakei LSK-104 under unfavorable cultivation conditions

The most widely used single-phase asynchronous motors are described and also substitution and vector dia-grams are reviewed. Theoretical and mathematical descriptions of processes of controlling and enabling asynchronous modes of operation were provided, on the basis of which computer models of a single-phase asynchronous motor in static and dynamic modes was created in the Matlab program. Experiments were per-formed on the real and virtual models, and the data obtained were processed and compared to confirm the adequacy of the developed virtual model.

The parameters of the seasonal dynamics of taxonomic diversity, abundance (number) and biomass of invertebrates (insects and spiders) on 10 different in appearance test areas in the background terrestrial biotopes of the floodplain in the interfluve of the Avacha and Pinachevskaya Rivers in 2018 and 2020 were determined. The maximum indicators of invertebrates abundance (from 200 specimens to 1 thousand or more per oblique by entomological net) in different biotopes were observed at different periods, but all of them occured in the period from mid-June to mid-October, usually from mid-July to August. The absolute values are various in different biotopes. The invertebrates biomass usually grows continuously from May to July, peaks in late July or the first half of August and then declines to a minimum by November with the onset of frost and before the first snowfall. The maximum invertebrates biomass per 1 m2 (during the peak value for each biotope) in 2018 was 0.033 – 0.097 g / m2 (0.998 g – 2.9 g per mowing), the average value (n = 10) was 0.049 g / m2. This index was less in 2020. The average value of insect biomass for 2 seasons per conditional 1m2 of the river floodplain in the studied area was about 0.029 g. Insects predominate among invertebrates, but spiders also occupy a significant part: 18% in abundance (number) and 38% in biomass, respectively,according to the results of mowing in 2018.
测定了2018年和2020年阿瓦恰河和皮纳切夫斯卡亚河河漫滩背景陆生区10个不同外观试验区无脊椎动物(昆虫和蜘蛛)的分类多样性、丰度(数量)和生物量的季节动态参数。不同生物区无脊椎动物丰度的最高指标(昆虫网测200 ~ 1000只/斜)出现在不同时期，但均出现在6月中旬~ 10月中旬，通常出现在7月中旬~ 8月。在不同的生物群落中，其绝对值是不同的。无脊椎动物的生物量通常从5月到7月连续增长，在7月下旬或8月上半月达到峰值，然后在11月霜冻和初雪前降至最低。2018年无脊椎动物生物量最大值为0.033 ~ 0.097 g / m2(每刈割量为0.998 ~ 2.9 g)，平均值(n = 10)为0.049 g / m2。该指数在2020年有所下降。研究区河漫滩条件1m2 2季昆虫生物量平均值约为0.029 g。根据2018年的割草结果，昆虫在无脊椎动物中占主导地位，但蜘蛛也占据了相当大的一部分:丰富度(数量)为18%，生物量为38%。

The article is dedicated to study of the atmospheric noise properties in the range of intermediate and decameter waves in the Western Bering Sea zone, where such observations were not carried out earlier. Since it is impossible to use the radio equipment of ships for such measurements, we used devices using the technology of software-defined radio systems. The measurements were carried out along the coast of Kamchatka and made it possible to establish the characteristic temporal, spatial and frequency variations in the parameters of atmospheric noise. It was found that the radio noise intensity distributions proposed due the recommendations of the International Telecommunication Union differ significantly from the real ones. The obtained data analysis showed the possibility of realizing a decameter range of circumpolar latitudes, unfavorable for radio engineering systems – a sharp increase in the intensity of radio noise due to the coincidence in time of several thunderstorm activity foci and a simultaneous decrease in absorption in the ionosphere.

Expanding of food products range for younger children (3–7 years old) through the development of a new technology of functional products is an actual research topic, since the products of this group available on the market do not have a wide choice. The research results upon the justification of the functional product ‟Fish sausages” technology using local raw materials and modern technological equipment are presented in the article. Optimal heat treatment modes of research objects are determined. A technological scheme of cooking has been developed. A sensory analysis of the developed product was carried out; the quality and safety indicators of fish sausages were studied.
