important species European hake which constitutes 50% of the Sea of Marmara
demersal fisheries, has been subjected to estimate age, growth characteristics
and natural mortality. Bottom trawl hauls were carried out in 19 stations
representing the entire Marmara Sea. Sea surveys were performed in different
time periods from 2009 to 2011 (September 2009, December 2009, December 2010
and December 2011). A total of 274 sagittal otoliths (117 females, 75 males and
82 unidentified individuals) were obtained from 2009, 2010 and 2011. Sex ratio
was calculated 1:1.5 males to females. Age composition was 0+ to 4+ years, most
observed age group was 2+ both for female and male (37%).  </span> <span style="font-size:12px;">Growth parameters determined by von

strongly support the fast growth hypothesis of </span> <i> <span style="font-size:12px;">M. merluccius </span> </i> <span style="font-size:12px;">. Growth rates clearly differ between males and
females in this sea which shows hake growth depends on sex.  </span> </span> <span lang="en-us" style="font-size:10pt;" xml:lang="en-us"> </span> </p> <p> </p> <p> </p>}, number={2}, publisher={Çanakkale Onsekiz Mart Üniversitesi}, organization={The Scientific and Technological Research Council of Turkey (TUBİTAK)}
