Length weight relationship (LWR) studies have an
important role in estimating population biomass, determining growth rate and
stock status of fishes. In this study a total
of 133 scaldback, Arnoglossus kessleri Schmidt,
1915 were caught in IskenderunBay between September
2014 and May 2015 using a commercial bottom trawler. As a result, the estimates
for b parameter of the LWR ranged between and 2.97, 2.68 and 2.74 for males,
females and both sexes, respectively. Fulton’s condition (KF)
factor values also revealed significant variations (p<0.01) for female
(1.089) and male (1.100) specimens of A.
kessleri. The 11.9 cm
long male individual found in this study was the longest individual recorded
for the Mediterranean Sea. No information
currently exists on the length weight relationship of A. kessleri in the Mediterranean coast of Turkey.
Therefore, this paper is an important contribution to the science and fisheries
management applications for this species.

Boy-ağırlık ilişkisi
çalışmaları populasyonun biyokütlesinin tahmnini, büyüme oranının belirlenmesi
ve balıkların stok durumunun hesaplanmasında önemli bir role sahiptir. Bu
çalışmada 133 Arnoglossus kessleri Schmidt, 1915 Eylül
2014 ve Mayıs 2015 tarihleri arasında İskenderun Körfezi’nden avlanmıştır.
Sonuç olarak boy ağırlık ilişkisinin b parametresi erkekler, dişiler ve tüm
bireyler için sırasıyla; 2.97, 2.68 ve 2.74 olarak hesaplanmıştır. Fulton’un kondisyon
(KF) faktor değeri A. kessleri. Için
dişi (1.089) ve erkek (1.100) bireylerde önemli bulunmuştur (p<0.01). Bu
çalışmada 11.9 cm
uzunluğunda bulunan erkek birey, Akdeniz için kaydedilen en uzun bireydir.
Türkiye’nin Akdeniz kıyılarında A.
kessleri’nin boy-ağırlık ilişkisine ait mevcut bir bilgi bulunmamaktadır.
Bu nedenle bu makale bu tür için bilime ve balıkçılık yönetim uygulamalarına
önemli katkı sağlamaktadır.
