Аннотация: The article presents not only theoretical background for the primary production (PP) assessment based on hydrochemical indices, but also numerous examples of the PP assessment for polar waters, upwelling zones, and ultraoligotrophic tropical waters. All advantages of the PP assessment based on hydrochemical parameters are shown, including a better representation and a more thorough assessment of PP in the Wordld ocean.

Аннотация: The instrumental methods that allow to determine authentically the environmental characteristics in real time "in situ" are considered. Their classification is developed basing on physics measurements and on interpretation of hydrobiological data as well. The main attention is given to meters using rapid optical measurement principles to conduct both rapid estimation of fish food base and the character of its formation. The main criterion for choosing meters is their methodological compatibility with CTD-complexes. Modern serial models for optical measuring instruments and recommendations for their use are presented from the standpoint of significance for fisheries.

Hydrochemical Features of Primary Production within the Peruvian and Canary Upwelling Areas [Электронный ресурс] / Dukhova, L.A., Sapozhnikov, V.V. // Modern methods for assessing the biological productivity of waters in industrial areas of the World ocean: VNIRO proceedings. - M.: VNIRO Publishing, 2014. - V. 152. - P. 85-100. - 2014

Аннотация: General features of water mass dynamics, as well as the processes responsible for higher biological productivity, appear to be similar for the geographically distinct areas of the Peruvian and Canary upwelling ecosystems. Variations in productivity of both ecosystems are driven by regional specifics of the upward flow, including the hydrochemical parameters of the upwelled waters. Northern sub-division of the Peruvian upwelling and southern sub-division of the Canary upwelling ecosystems are supplied by waters of the subsurface poleward flows over slope, for the rest it is water of Peruvian Coastal and Canary currents respectively. Biological productivity of these ecosystems was estimated indirectly using the hydrochemical data, and these results correspond well with direct observational data.

Hydrochemical Structure of Water Masses in Areas of the Antarctic Krill (Euphausia Superba Dana) Fisheries [Электронный ресурс] / Arzhanova, N.V., Artamonova, K.V. // Modern methods for assessing the biological productivity of waters in industrial areas of the World ocean: VNIRO proceedings. - M.: VNIRO Publishing, 2014. - V. 152. - P. 118-132. - 2014

Аннотация: Antarctic krill (Euphausia superba Dana) is considered a most valuable fishing object in the Antarctic waters. According to some estimates, its stocks totals hundred million tons. Besides, krill makes the basic part of feeding ration for numerous consumers, including sea birds, seals, whales, etc. Hydrochemical conditions in areas of the Antarctic krill concentrations in the Southern Ocean are reviewed. We have identified hydrochemical parameters which allow us to differentiate main water masses in the Antarctic waters (i.e. waters associated Antarctic Circumpolar Current (ACC) vs. water with the high-latitude modification associated with continental seas) and distinguish a zone of their interaction, the Secondary Frontal Zone (SFZ). This zone basically makes the areas of the krill dense concentrations.

Аннотация: Assessment of the nutrients supply of the primary production in the different parts of the Ob" Inlet was carried out using hydrological and dydrochemical ananysis. Features of formation of the primary production in the each separated areas and conditions of formation of the high-productivity zones were shown. It was shown that the Ob" Inlet is the high-productive water basin.
