As for (i), in 45% of the examined stocks, the official value for SSBpa was below the consensus estimates determined from three different methods. With respect to (ii), the official estimates of F-msy exceeded natural mortality M in 76% of the stocks, although M is widely regarded as natural upper limit for F-msy. And regarding (iii), the age at first capture was below the age at maturity in 74% of the stocks. No official estimates of the stock size (SSBmsy) that can produce the maximum sustainable yield (MSY) are available for the north-east Atlantic. An analysis of stocks from other areas confirmed that twice SSBpa provides a reasonable preliminary estimate. Comparing stock sizes in 2013 against this proxy showed that 88% were below the level that can produce MSY. Also, 52% of the stocks were outside of safe biological limits, and 12% were severely depleted. Fishing mortality in 2013 exceeded natural mortality in 73% of the stocks, including those that were severely depleted. These results point to the urgent need to re-assess fisheries reference points in the north-east Atlantic and to implement the regulations of the new European Common Fisheries Policy regarding sustainable fishing pressure, healthy stock sizes and adult age/size at first capture.</subfield> </datafield> <datafield tag="245" ind1=" " ind2=" "> <subfield code="a">Revisiting safe biological limits in fisheries</subfield> </datafield> <datafield tag="909" ind1="C" ind2="O"> <subfield code="p">user-tubitak-destekli-proje-yayinlari</subfield> <subfield code="o">oai:zenodo.org:57607</subfield> </datafield> <datafield tag="542" ind1=" " ind2=" "> <subfield code="l">open</subfield> </datafield> <datafield tag="100" ind1=" " ind2=" "> <subfield code="u">GEOMAR Helmholtz Ctr Ocean Res, Dusternbrooker Weg 20, D-24105 Kiel, Germany</subfield> <subfield code="a">Froese, Rainer</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="a">user-tubitak-destekli-proje-yayinlari</subfield> </datafield> <datafield tag="856" ind1="4" ind2=" "> <subfield code="z">md5:37c0a0399e7f2877f7a65e1a7edfb061</subfield> <subfield code="s">140</subfield> <subfield code="u">https://aperta.ulakbim.gov.trrecord/57607/files/bib-d779d598-427b-42fe-8da8-5597bba35bfd.txt</subfield> </datafield> <datafield tag="024" ind1=" " ind2=" "> <subfield code="2">doi</subfield> <subfield code="a">10.1111/faf.12102</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">CNR, Ist Sci & Tecnol Informaz A Faedo, Via Moruzzi 1, I-56124 Pisa, Italy</subfield> <subfield code="a">Coro, Gianpaolo</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ British Columbia, Fisheries Ctr, Sea Us Project, 2202 Main Mall, Vancouver, BC V6J 1Z4, Canada</subfield> <subfield code="a">Kleisner, Kristin</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Istanbul Univ, Inst Marine Sci & Management, Muskule Sok 17, TR-34134 Istanbul, Turkey</subfield> <subfield code="a">Demirel, Nazli</subfield> </datafield> <datafield tag="650" ind1="1" ind2="7"> <subfield code="a">cc-by</subfield> <subfield code="2">opendefinition.org</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="a">publication</subfield> <subfield code="b">article</subfield> </datafield> <datafield tag="260" ind1=" " ind2=" "> <subfield code="c">2016-01-01</subfield> </datafield> </record>
