Аннотация: The potencials of the modern analytical approach to assessment of a total allowable catch (TAC) as the key fisheries management measure were demonstrated on the example of the stock of walleye pollock Theragra chalcogramma (Pallas 1814) in the East of the Okhotsk Sea. The database (DB) of the information system (IS) "Fishery" was used as an alternative source of the initial information for analysis. The observed catches per unit effort ware converted into stock abundance indices. The main emphasis was placed on the following methodological issues: standardization of the observed values of catch per unit effort using generalized linear models (GLM), justifying the choice of the base model of the stock dynamics and the harvest control rule (HCR), risk analysis and other diagnostic procedures aimed to improve the efficiency of the aquatic biological resources management.

Аннотация: To estimate the red king crab abundance stochastic version of cohort CSA model was applied based on catch from trawl and pot surveys as well as fishery efficiency data. 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 regression methods are shown not to allow assessing an open local stock as in the case of the Leslie and De Lury classic models. To solve this problem, a method based on Kalman filter is suggested. Besides, there is given a description of some methodical weak points of De Lury model, which make it less preferable regarding to Leslie's model. This work presents the Leslie's Generalized Model with Kalman filter (LGM KF), which is aimed to reconstruct a stock dynamics during fishery using the temporary series of catches on local areas in the presence of migratory flows and neglected catch.

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.
