Egner vintertoktet seg til overvåking av endringer i fiskesamfunnet i Barentshavet? : en gjennomgang av metodikk og data fra 1981-2007
Johannesen, Edda; Wenneck, Thomas de Lange; Høines, Åge S.; Aglen, Asgeir; Mehl, Sigbjørn; Mjanger, Hildegunn; Fotland, Åge; Halland, Tor Ivar; Jakobsen, Tore (Fisken og havet, Research report, 2009-12-10)The winter survey (1981-) is the longest bottom trawl time series in the Barents Sea. The survey is used as tuning series in cod and haddock assessment, but change and ecosystem-based management, necessitates the study of ... -
Evaluation of the proposed harvest control rule for Northeast Arctic saithe: background, population model, parameters, data and preliminary analyses

Methods of index calculation and presentation of fish abundance data using standard computer programs
Fotland, Åge; Mehl, Sigbjørn; Sunnanå, Knut (PINRO-IMR Symposium, Conference object, 1995)Standard 0-group indices distribution maps are now produced based on hand-drawn maps using AutoCad with some additional procedures. This paper briefly describes the mathod. The paper further describes ways of importing ... -

NEA saithe XSA runs with different survey tuning series
Mehl, Sigbjørn; Fotland, Åge (Working paper, 2010-02)New tuning series from a combined and improved survey gives lower and more stable S. E. Log q residuals than the tuning series presently used. However, the retrospective trend is still poor and the estimates of F and SSB ... -

Retrieving the times series of input data for assessment of NEA saithe
Fotland, Åge; Mehl, Sigbjørn (Working paper, 2010-04)This WD is meant as an explanation to how the times series input files for the assessment of NEA saithe is expanded to age 15+ at the 2010 AFWG. Table 3 and 4 includes age group 2. This age group is not used in the current ... -

Some exploratory XSA runs for NEA-saithe (using FLR)
Mehl, Sigbjørn; Fotland, Åge (Working paper, 2010-02)S.E_Log q residuals and scaled weights from XSA diagnostics are presented together with estimates of Fbar and SSB in the final assessment year for 10 different single and multi fleet runs. The purse seine tuning series ... -
