    • Inclined water flow and its applications for reduced bycatch in shrimp trawls 

      Engås, Arill; Gamst, Kjell Arne; Graham, Norman (IMR/PINRO Joint Report Series, Conference object, 2001)
      The use of the Nordmøre grid in the Pandalus fishery has significantly reduced the bycatch of finfish. Grids operate on physical separation based on size to achieve bycatch reduction. However, problems arise when the size ...

    • Using mixed models to combine smooth size-selection and catch-comparison curves over hauls 

      Fryer, F. J.; Zuur, Alain F.; Graham, Norman (Journal article; Peer reviewed, 2003)
      Parametric size-selection curves are often combined over hauls to estimate a mean selection curve using a mixed model in which between-haul variation in selection is treated as a random effect. This paper shows how ...
