Age and Growth of European Hake, Merluccius merluccius in the Sea of Marmara

Yıl 2019, Cilt: 2 Sayı: 2, 147 - 154, 27.12.2019

Öz

Within this study, the most
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%). 
Growth parameters determined by von
Bertalanffy equation were found as L
= 57.51 cm K=0.27 y-1
and t
0=-0.57 y-1. Natural mortality was estimated 0.41 y-1.
Our results obtained from the Marmara Sea
strongly support the fast growth hypothesis of
M. merluccius. Growth rates clearly differ between males and
females in this sea which shows hake growth depends on sex.

Marmara Denizi’nde Berlam Balığının Yaş ve Büyümesi

Yıl 2019, Cilt: 2 Sayı: 2, 147 - 154, 27.12.2019

Öz

Bu çalışmada, Marmara Denizi demersal balık avcılığının
%50’sini oluşturan ve stoğu aşırı sömürülmüş berlam türünün (
Merluccius merluccius) yaş ve büyüme
parametreleri, doğal ölüm oranı belirlenmiştir. Farklı 4 zaman diliminde (Eylül
2009, Aralık 2009, Aralık 2010, Aralık 2011) Marmara Denizi’nin genelini
yansıtacak 19 istasyonda dip trol çekimleri yapılarak elde edilen 274 adet
bireyin sagitta otolitlerinden yaş okumaları gerçekleştirilmiştir (117 dişi, 75
erkek, 82 cinsiyeti belirsiz birey). Erkek dişi oranı 1:1.5 olarak
belirlenmiştir. Yaş okumaları sonucunda bireylerin 0+ ile 4+ yaş aralığında
olduğu, 2+ yaş grubunun hem dişilerde hem de erkek bireylerde baskın olduğu
görülmüştür. von Bertalanffy büyüme parametreleri L
= 57.51 cm,
K=0.27, y
-1 t0=-0.57 y-1 olarak
hesaplanmıştır. Doğal ölüm oranı 0.41 y
-1 olarak belirlenmiştir.
Elde ettiğimiz bu sonuçlar Berlam’ın hızlı büyüme hipotezini güçlü bir biçimde
desteklemektedir. Dişi ve erkek bireylerin büyüme oranındaki farklılık berlamın
büyümesinin cinsiyete bağlı olduğunu göstermektedir
