Penaeus semisulcatus De Haan, 1844 was collected in Iskenderun Bay, from November 2009 to October 2010, by monthly bottom trawl operations. The male : female ratio was determined as 1 : 1, and the spawning period was found to be from January to June, while peaking two times a year, namely in January and in March. The L∞ and K for males were estimated at 42.00 mm CL and 1.8 year−1, respectively, and for the females 63.00 mm CL and 1.90 a year−1. Using the L∞ and K estimates for both sexes, the instantaneous rate of natural mortality (M) for males and females were calculated as 1.50 and 1.97 year−1, respectively, at 22°C water temperature on average. The instantaneous rates of total mortalities (Z) were 4.04 year−1 for males and 6.39 year−1 for females, and fishing mortalities (F) for males were 2.24 year−1 and for females 4.42 year−1. Thus, the exploitation rates (E) were 0.65 year−1 and 0.69 year−1 for males and females, respectively. The results clearly indicate overfishing for P. semisulcatus in the study area.

İSKENDERUN KÖRFEZİ’NDE AKDENİZ KARİDESİ (PENAEUS KERATHURUS FORSKAL,1775)’NİN BÜYÜME PARAMETRELERİ ÖZ Bu çalışmada, İskenderun Körfezi’nde Kasım 2009-Aralık 2010 tarih aralığında aylık olarak dip trolü çekimlerinden elde edilen Akdeniz karidesi (Penaeus kerathurus)’nin büyüme parametreleri belirlenmiştir. İncelenen 120 örnek bireyden 41 adedi erkek ve 79 adedi dişi olup; erkek/dişi oranı yaklaşık 1/2 dir. Örneklerin total boyları 8.5-19.1cm, total ağırlıkları 4.4-58.41g değerleri arasında değişim göstermekte ve ortalama boy 13.97±2.19cm ile ağırlıkları 24.09±11.19g olarak belirlenmiştir. Boy-Ağırlık ilişkisi toplam eşeyde W=0.0108*TL (R=0.9042) olup; büyümede negatif allometrik büyüme özelliği gösterdiği saptanmıştır. Von Bertalanffy Büyüme sabitleri L∞=20.95cm, K=0.470yıl -1 ve t0=-0.5138yıl -1 olduğu belirlenmiştir. Toplam ölüm oranı (Z), doğal ölüm (M) ve balıkçılık ölüm oranı (F) ile stoktan yararlanma düzeyi (E) sırasıyla 2.45yıl, 1.09yıl, 1.36yıl ve 0.55yıl olarak saptanmıştır. Anahtar Kelimeler: Akdeniz Karidesi (Penaeus kerathurus), İskenderun Körfezi, Büyüme Parametreleri, Ölüm Oranları, Stoktan Yararlanma Oranı
