Different ecosystem models often provide contrasting predictions (model uncertainty), which is perceived to be a major challenge impeding their use to support ecosystem-based fisheries management (EBFM). The focus of this manuscript is to examine the

Extension of biomass estimates to pre-assessment periods using density dependent surplus production approach.

Autor: Jan Horbowy, Maciej T Tomczak

Publikováno v: PLoS ONE, Vol 12, Iss 11, p e0186830 (2017)

Biomass reconstructions to pre-assessment periods for commercially important and exploitable fish species are important tools for understanding long-term processes and fluctuation on stock and ecosystem level. For some stocks only fisheries statistic

A new approach for estimating the fishing mortality benchmark Fmsy (fishing pressure that corresponds to maximum sustainable yield) is proposed. The approach includes density-dependent factors. The analysis considers 53 data-rich fish stocks in the N

Comparing the steady state results of a range of multispecies models between and across geographical areas by the use of the jacobian matrix of yield on fishing mortality rate

Like other fisheries models, multispecies models are subject to various sources of error. However, with regard to their use for ecosystem-based fisheries management (EBFM) between model errors are likely to be most important. As multispecies models a

Effects of multispecies and density-dependent factors on MSY reference points: example of the Baltic Sea sprat

Autor: Anna Luzenczyk, Jan Horbowy

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 74:864-870

In this paper, maximum sustainable yield (MSY) parameters for the Baltic Sea sprat (Sprattus sprattus) are estimated in relation to pressure from cod (Gadus morhua) predation and the influence of density dependence on sprat growth. This study is base
