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.

Аннотация: This book summarizes the results of the project on experimental cultivation of the red king crab Paralithodes camtschaticus (Tilesius, 1815) under laboratory and semi-industrial conditions. The book consists of two chapters. In chapter 1 ("Biology") the results of the studies on the red king crab early development are described and compared with previous data. This knowledge of the red king crab biology at the early life history stages served as a basis for establishing feasible culture methods and techniques described in chapter 2 ("Culture"). Culture methods and techniques established in accordance with specific requirements of each stage allowed to obtain viable red king crab juveniles from the eggs in 2 months with overall survival equaling 30-35%.

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.

The status of commercial stock of the red king crab in the Barents Sea at present shall not be regarded as critical. Yet strong pressure from fishery produced negative impact on biological and fisheries parameters of the population in 2008-2009.

Аннотация: The known class of models of the fishery depletion is enlarged for a case of the non-isolated population. Dynamics of the local open stock under the fishery influence is described using the balance differential equations. A depletion model for the homogeneous-by-space stock is given as a Cauchy task. Its solution was obtained using the method of the constant variation. The analogous model for the heterogeneous-by-space stock is formulated as a Neumann task with non-stationary boundary conditions. A solution of this task was obtained as the source functions.

Аннотация: The paper presents materials on diet composition and feeding peculiarities of 16 non-target fish species in the Kara Sea in 2007-2011. Diet similarity among studied species as well as among diet of fishes in the Kara Sea and the northern Barents Sea were considered. Three trophic groups were revealed - most species (10 species) were benthivorous, 3 species - planctivorous and 3 species - piscivorous. It was shown that there are potential feeding competitors for commercial fish (polar cod, Greenland halibut). Generally the trophic structure of the Kara Sea fish community is characterized by dominance of benthivorous species (by species number) and low portion of piscivorous species, but the most abundant species belong to planctivorous fish.

Аннотация: Changes of stages of redroductive cycle, molting cycle and some other features of biology of the northern shrimp (Pandalus borealis eous) were studied based on data of daily biological analysis, grouped to five days during 10 months (from March to December) of the calendar year. Materials were collected in Pritaujskiy area in northern part Sea of Okhotsk. Reproductive cycle of females lasts for two years: during first year gonads developed up to the spawning and in the second one females carried eggs on pleopods up to hatching of larvae and beginning a new cycle. Changes can be traced by the share of the relevant stages in the total number of individuals in three groups: males, females of first year reproductive cycle and females of second one. The males have two molts for the year and females, according to the spawning cycle have three molts during two years. All molts lasts 2-3 months and diverge in terms. By changes of share of females of first and second year of reproductive cycle hypothesis about vertical migrations was made. The share of females with sternal spines, that take part in process of reproduction first time, is about 45%, which means that females are able take part to three spawning cycles.

Аннотация: This work is based on the materials collected during scientific observation of Commander squids fishery in the waters adjacent the Northern Kuril Islands from 31 May till 18 June, 2014. The study revealed shorterm (10-12 days) cycles of density and composition of squid aggregations. Each phase of the cycle may be characterized by specific density of squid aggregations, sex ratio and maturity stages composition. A hypothesis is provided that this cyclicity appears as a result of migration of spatially structured squid shoals through the fishing ground in the Northern Kuril Islands area.
