Regional variability in reproductive traits of European hake Merluccius merluccius L. populations

Method development and evaluation of stock reproductive potential of marine fish

“…GSI as well as the total relative number of developing oocytes (NDO rel ) followed the same trend as BF rel , although the overall pattern differed in the two areas of study . NDO rel did not vary with maturity stage, corroborating that the fecundity of European hake is indeterminate Korta et al, 2010a). Based upon the results on spawning fraction, the European hake spawns once every 5-7 days during January-March in both areas but once every 10 days or more in the rest of the year .…”

“…Here the focus was devoted on how to obtain reliable estimates of realised fecundity, daily egg production rates and age at maturity in the Bay of Biscay and Galician Shelf populations (Domínguez-Petit et al, 2008;Korta et al, 2010a). Relative batch fecundity (BF rel ) showed significant differences among years in both areas, indicating differences in productivity.…”

Variability in total egg production and implications for management of the southern stock of European hake

“…The second dataset gathers information on individual reproductive biology (microscopic maturity stage, fecundity and egg quality) and was available for the years 1999, 2000, 2003 and 2004, although egg quality information was available only for 2003 and 2004 (see Section 2.2). The methods used to produce the data, and the database it self, is the same as that used in , Korta et al (2010) and .…”

Using classification trees to study the effects of fisheries management plans on the yield of Merluccius merluccius (Linnaeus, 1758) in the Alboran Sea (Western Mediterranean)

“…European hake (M. merluccius (Linnaeus, 1758)) is one of the target demersal species of the Mediterranean fishing fleets, largely overexploited in Europe (Aldebert et al, 1993;Aldebert and Recasens, 1996;De Pontual et al, 2003;GFCM, 2004GFCM, , 2005GFCM, , 2006GFCM, , 2007GFCM, , 2008ICES, 2004ICES, , 2008Korta et al, 2009;Orsi-Relini et al, 2002).…”
