Abstract

This study was carried out from September 2002 to April 2003 in Karataş Coasts (Iskenderun Bay). A total of 212 specimens were trawled by monthly sampling in 2002-2003 fishing season. The age of Merluccius merluccius varied from I to IV age classes. The mean total length and total weight values was calculated as 12.872.67 cm and 22.9312.86 g respectively and the calculated length-weight relationship was W=0.0267L2.5309. The von Bertalanffy growth parameters were L= 42.61 cm, K= 0.123 year-1 and to= -1.906 year. Total mortality was 2.41, the
natural mortality was 0.29 and the fishing mortality was estimated to be 2.12. The exploitation rate calculated as 0.88 using value of M and F. Therefore, the population of M. merluccius off the Karatas coast exploited over the optimum level because of overfishing pressure.

Abstract

Bu
çalışma, Eylül 2002-Nisan 2003 tarihleri arasında, Karataş Kıyıları’nda
(İskenderun Körfezi) aylık trol çekimleri yapılarak gerçekleştirilmiştir. Elde
edilen 210 bireyin I-V yaş grupları arasında değişim gösterdiği belirlenmiştir.
Örneklenen bireylerin boyları 6.10-17.80 cm ve ağırlık değerleri 2.14-59.65 g
arasında değişim göstermekte olup; ortalama boy ve ağırlık değerleri ise sırasıyla
8.95±2.80 cm ve 10.02±11.28 g olarak hesaplanmıştır. Spicara smaris için boy-ağırlık ilişkisi W=0.0066*L3.1879 ve von
Bertalanffy boyca büyüme sabitleri L¥=22.76 cm, K=0.213 yıl-1
ve to=-0.805 yıl olarak hesaplanmıştır. Ayrıca toplam ölüm
oranlarının üssi katsayısı Z= 1.68, doğal nedenlerle olan ölüm oranı M=0.49 ve
balıkçılık nedeniyle olan ölüm oranının üssi katsayısı ise F=1.19 ve stoktan
yararlanma düzeyi E=0.71 olarak hesaplanmıştır.
