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 ... -
An overall indicator for the good environmental status of marine waters based on commercially exploited species
Demirel, Nazli; Sampang, Arlene (2015)An indicator is presented to assess and monitor the good environmental status of national marine waters based on the status of commercially exploited marine fishes and invertebrates, including fully-assessed as well as ... -
Estimating fisheries reference points from catch and resilience
Demirel, Nazli; Kleisner, Kristin M.; Froese, Rainer; Coro, Gianpaolo (2017)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 ... -
Ichthyoplankton dynamics in a highly urbanized estuary
Demirel, Nazli (2015)Spatio-temporal distribution and composition of ichthyoplankton assemblages were studied in the Golden Horn estuary (Istanbul) over a 10-month period. Environmental parameters were considered to determine the environmental ... -

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 ... -
Revisiting safe biological limits in fisheries
Coro, Gianpaolo; Demirel, Nazli; Kleisner, Kristin (2016)The appropriateness of three official fisheries management reference points used in the north-east Atlantic was investigated: (i) the smallest stock size that is still within safe biological limits (SSBpa), (ii) the maximum ... -
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 ... -
Weight-length relationships of 28 fish species in the Sea of Marmara
Murat Dalkara, Elif (2012)Weight-length relationships (WLRs) for 28 fish species were investigated in an enclosed basin in the Sea of Marmara. Due to low sample sizes (<15), 11 species were not taken into account, but length results were represented. ...
