Аннотация: The book considers relationships between climate changes and fish productivity of oceanic ecosystems. Long-term time series of various climatic indices, dynamics of phyto- and zooplankton and variation of commercieal fish populations in the most productive oceanic areas are analyzed. Comparison of climate index fluctuations and populations of major commercial species for the last 1500 years indicates on a coherent character of climate fluctuations and fish produciton dynamics. A simple stochastic model is suggested that makes it possible to predict trends of basic climatic indices and populations of some commercial fish species for several decades ahead. The approach based on the cyclic character of both climate and marine biota changes makes it possible to improve harvesting of commercial fish stocks depending on a phase (ascending or descending) of the long-term cycle of the fish population. In addition, this approach is helpful for making decisions on long-term investments in fishing fleet, enterprises, installations, etc. The results obtained also elucidate the old discussion: which factor is more influential on the long-term fluctuations of major commercieal stocks, climate of commercial fisheries?

Аннотация: Finding out the population structure of pollock is a complex procedure because of the species seasonal and ontogenetic migration intensity which undergoes significant interannual variations as dependent on the climate and ocean conditions, the abundance of population, and of the species in total. That is why, in order to obtain a comprehensive picture, the book reviews the results of a decade of integrated research (1996-2004) which included 26 cruises, 21 trawl surveys, 11 echointegration trawl surveys, 8 surveys of the juveniles and five ichthyoplankton surveys made in the northern, western and eastern parts of the Bering Sea where a novel approach developed by VNIRO was applied which involved serial repetition of surveys during a year. For the first time the results of such surveys made it possible to obtain information on the stock structure dynamics. The monograph reviews the organization of the Bering Sea pollock population using a virtually full set of approaches to the study of populations: genetic, ecological (biogeocenotic), morphological, biochemical, physiological, energy and ethological. The functional structure dynamics of the range between the 1970s and the present time was analyzed, as based on the own and published data.

Our results obtained using the TISVPA model, the model aimed at robustness and with attention to generation-dependent peculiarities, may indicate that the XSA-derived results may lead to erroneous perception of the stock and hardly can be regarded as the only and sufficiently reliable basis for further management decisions.

Аннотация: Dynamics of the fishable biomass of the Barents Sea cod in 2000-2007 were stable, with an upward trend in recent years (2005-2007). The result of a correlation analysis made is that the "parents-progeny" relationship is not provided with a significant level, whereas the recruitment of cod aged 3 is directly related to the mean water temperature within 0-200 m, and correlation coefficient was 0.68. The analysis of the dependence of recruitment on water temperature was made formal which enabled us to generate a prognostic model, and evaluate the size of recruitment at age 3. The estimated fishable biomass forecat and TAC for cod of the Barents Sea based on GIS method showed that a possible yield in 2008 will be 629 thousand tons which is 1.5 times greater than it had been suggested by the AFWG.

Поскольку ярусный промысел в гораздо большей степени чем тралы, ориентирован на отлов крупной, старшевозрастной рыбы, предлагается использовать эту специфику ярусного лова для ослабления возросшего в последние годы каннибализма в популяции трески. По мнению авторов, фактор каннибализма на фоне относительно благоприятных гидрологических условий может быть основной причиной наблюдающегося очередного сокращения запаса трески. Меры, направленные на расширение масштабов ярусного лова, особенно отечественного, доля которого составляет сейчас не более 6%, сдерживали бы негативное влияние каннибализма на запас трески./ Based on the data of the industry monitoring system of Rosrybolovstvo, the Ministry of Trade, Industry and Fisheries of Norway, the materials of the ICES Working Group on Arctic Fishing (AFWG) and the protocols of the Joint Russian-Norwegian Fishery Commission (JRNFC), as well as data collected by the scientific observers of VNIRO on longline vessels of the «Persei» Company in 2013–2018, the current state of Russian and Norwegian fishing in the Barents Sea, carried out by bottom fishing gears, especially longline fishing, is analyzed. Since longline fishing is much more focused on large, older fish, it is suggested that this specificity of longline fishing is used to reduce the increased cannibalism in the cod population in recent years. In our opinion, the phenomenon of cannibalism against the relatively favorable hydrological conditions may be the main reason for the observed next reduction in the cod stock. Measures aimed at expanding the scale of longline fishing, especially domestic fishing, which currently accounts for no more than 6%, would moderate the negative impact of cannibalism on cod stocks.

Меры, направленные на расширение масштабов ярусного лова, особенно отечественного, доля которого составляет сейчас не более 6%, сдерживали бы негативное влияние каннибализма на запас трески./ Based on the data of the industry monitoring system of Rosrybolovstvo, the Ministry of Trade, Industry and Fisheries of Norway, the materials of the ICES Working Group on Arctic Fishing (AFWG) and the protocols of the Joint Russian-Norwegian Fishery Commission (JRNFC), as well as data collected by the scientific observers of VNIRO on longline vessels of the «Persei» Company in 2013–2018, the current state of Russian and Norwegian fishing in the Barents Sea, carried out by bottom fishing gears, especially longline fishing, is analyzed. Since longline fishing is much more focused on large, older fish, it is suggested that this specificity of longline fishing is used to reduce the increased cannibalism in the cod population in recent years. In our opinion, the phenomenon of cannibalism against the relatively favorable hydrological conditions may be the main reason for the observed next reduction in the cod stock. Measures aimed at expanding the scale of longline fishing, especially domestic fishing, which currently accounts for no more than 6%, would moderate the negative impact of cannibalism on cod stocks.

Аннотация: Veined rapa whelk (Rapana venosa) was first recorded in the Black Sea in 1947 near Novorossiysk and by the 1970s it spread along the whole Black Sea coasts. In this time interval the rapa whelk population was stabilized in number and during the 1980s its annual fluctuations depended only from climate changes. In recent years we have observed a decrease in rapa whelk size, its earlier spawning and larval settling on submerged substrate and flattening of regional morphological changes. Based on the data analysis for 1970-2010, we offered the hypothesis that the changes in the rapa whelk biology had occurred owing to the change of the lecithotrophic larval development pattern from the years of abundant food supply to the planktotrophic one in the years with low feeding benthos mass.
