A Study on Recent Variations in the Population Structure of European Anchovy (Engraulis encrasicolus L., 1758) in the Southern Black Sea.

Öz

Güney Karadeniz’deki hamsi (Engraulis encrasicolus L., 1758) populasyon yapısındaki son değişiklikler üzerine bir çalışma. Bu araştırma Karadeniz’in Güneyindeki Türkiye Sinop sahilinde 2000-2003 yılları arasında hamsi balığının stok yapısındaki değişikliklerin belirlenmesi için yürütülmüştür. Tüm örneklerde dişilerin ve erkeklerin oranı %59 ve %41 olarak belirlenmiştir. Uzunluk-ağılrık ilişkisi katsayısı b, 2000-2001, 2001-2002, 2002-2003 ve 2000-2003 av sezonları için sırasıyla 2.7101, 3.0568, 2.8946, 2.8695 olarak bulunmuştur. Sonuçlar hamsinin 0-3 yaşında olduğunu gösterdi. Von Bertalanffy büyüme parametresi L∞ (cm) av sezonları için sırasıyla 16.84 cm, 18.46 cm, 18.73 cm ve 18.91 cm olarak hesaplanmıştır. Tüm örneklerde (N=7487) toplam, doğal, avcılık ölüm oranları ve işletme oranı, Z=2.07 year-1, M=0.30 year-1, F=1.77 year-1 ve E=0.86 year-1olarak hesaplanmıştır
