The Estimation of the Size and Management of the Fisheries of the Harp Seal Pagophilus groenlandicus of the White Sea Population [Электронный ресурс] / Korzhev, V.A. // Modern aspects of quantitative analysis of the fishing raw material base: VNIRO proceedings. - M.: VNIRO Publishing, 2014. - V. 151.

Аннотация: The paper presents a detailed description of the mathematic model to be used to estimate abundance of the White Sea harp seal population and the input data required for the model implementation. The paper also describes the model parameters and methods of their assessment. Abundance of the harp seal from 1946 to 2012 was estimated. The data from research literature were used to analyse the dynamics of fertility parameters of the While Sea harp seal population and to show its effect on the stock assessment.

Assessment of the Dynamics of Fish Mortality in Exploited Populations (Cases of Selective Fisheries) [Электронный ресурс] / Kostitsyn, V.G. // Modern aspects of quantitative analysis of the fishing raw material base: VNIRO proceedings. - M.: VNIRO Publishing, 2014. - V. 151. P. 126-135. - 2014

Аннотация: Dynamics of mortality estimates in fish populations exposed to selective fishing netting (Kama and Votkinsk reservoirs) is analysed. It is found that mortality rates increase in middle and older age groups which are fished most strongly. On the example of a population for which there are estimates of absolute abundance (bream), near correspondence of mortality rates obtained on the basis of absolute abundance and by virtual calculations for modal age groups is demonstrated.

Аннотация: A modification to the acting Norwegian Spring-Spawning herring management plan is proposed. The modification links the choice of the target fishing mortality value to the estimates of recruitment for the distinct interval of preceding years.
