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.","PeriodicalId":107323,"journal":{"name":"Bulletin оf Kamchatka State Technical University","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124147234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 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.

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.","PeriodicalId":107323,"journal":{"name":"Bulletin оf Kamchatka State Technical University","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125186450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
