    • A critique of the balanced harvesting approach to fishing 

      Tsikliras, Athanassios C.; Froese, Rainer; Walters, Carl; Pauly, Daniel; Winker, Henning; Demirel, Nazli; Weyl, Olaf L. F. (2016)
      The approach to fisheries termed "balanced harvesting" (BH) calls for fishing across the widest possible range of species, stocks, and sizes in an ecosystem, in proportion to their natural productivity, so that the relative ...

      Pauly, Daniel; Walters, Carl; Demirel, Nazli; Holt, Sidney J.; Tsikliras, Athanassios C.; Weyl, Olaf L. F.; Winker, Henning; Froese, Rainer

    • A new approach for estimating stock status from length frequency data 

      Tsikliras, Athanassios C.; Dimarchopoulou, Donna; Scarcella, Giuseppe; Probst, Wolfgang Nikolaus; Dureuil, Manuel; Pauly, Daniel; Demirel, Nazlı; Froese, Rainer; Winker, Henning; Coro, Gianpaolo
      This study presents a new method (LBB) for the analysis of length frequency data from commercial catches. LBB works for species that grow throughout their lives, such as most commercially-important fish and invertebrates, ...

    • Estimating fisheries reference points from catch and resilience 

      Demirel, Nazli; Froese, Rainer; Coro, Gianpaolo; Kleisner, Kristin M.; Winker, Henning
      This study presents a Monte Carlo method (CMSY) for estimating fisheries reference points from catch, resilience and qualitative stock status information on data-limited stocks. It also presents a Bayesian state-space ...

    • Estimating stock status from relative abundance and resilience 

      Palomares, Maria Lourdes Deng; Demirel, Nazli; Scarcella, Giuseppe; Dureuil, Manuel; Pauly, Daniel; Froese, Rainer; Winker, Henning; Coro, Gianpaolo; Tsikliras, Athanassios C.; Dimarchopoulou, Donna
      The Law of the Sea and regional and national laws and agreements require exploited populations or stocks to be managed so that they can produce maximum sustainable yields. However, exploitation level and stock status are ...

    • On the pile-up effect and priors for L-inf and M/K: response to a comment by Hordyk et al. on "A new approach for estimating stock status from length frequency data" Reply 

      Coro, Gianpaolo; Scarcella, Giuseppe; Tsikliras, Athanassios C.; Dureuil, Manuel; Pauly, Daniel; Winker, Henning; Probst, Wolfgang Nikolaus; Demirel, Nazli; Dimarchopoulou, Donna (2019)
      <p>We thank Hordyk et al. (2019) for pointing out a typographical error in one of our equations, which has meanwhile been fixed in the online version of Froese et al. (2018) and addressed in a corrigendum for the printed ...

    • Reply to Andersen et al. (2016) "Assumptions behind size-based ecosystem models are realistic" 

      Weyl, Olaf L. F.; Demirel, Nazli; Holt, Sidney J.; Tsikliras, Athanassios C.; Winker, Henning; Pauly, Daniel; Walters, Carl (2016)
      In a recent publication (Froese et al., ICES Journal of Marine Science; 73: 1640-1650), we presented a critique of the balanced harvesting (BH) approach to fishing. A short section dealt with the size-spectrum models used ...

    • Status and rebuilding of European fisheries 

      Matz-Lueck, Nele; Tsikliras, Athanassios C.; Demirel, Nazli; Dimarchopoulou, Donna; Froese, Rainer; Winker, Henning; Coro, Gianpaolo; Scarcella, Giuseppe (2018)
      Since January 2014, the reformed Common Fisheries Policy (CFP) of the European Union is legally binding for all Member States. It prescribes the end of overfishing and the rebuilding of all stocks above levels that can ...
