Abstract

This research was carried out to estimate variation of stock structure anchovy (Engraulis encrasicolus, L. 1758) (N=7487) of the in Sinop Turkish coast in the southern of the Black Sea between 2000 and 2003. The mean sex ratio was 59 % (female): 41 % (male). The b constant of weight-length relationships were 2.7101, 3.0568, 2.8946 and 2.8695 for 2000-2001, 2001-2002, 2002-2003, and 2000-2003 fishing seasons, respectively. The result showed that fish were 0-3 years old. The von Bertalanffy growth parameter value of L∞ (cm) were 16.84 cm, 18.46 cm, 18.73 cm and 18.91 cm for fishing seasons, respectively. Total (Z), natural (M), fishing (F) mortality rates and exploitation rate (E) were Z=2.07 year-1, M=0.30 year-1, F=1.77 year-1, E=0.86, respectively for overall samples.

Özet

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.
