A preliminary study on the population dynamics parameters of whiting (Merlangius merlangus euxinus) in Turkish Black Sea coastal waters

Öz:

Karadeniz'in Türkiye kıyılarında yayılış gösteren mezgitin (Merlangius merlangus euxinus) yaş-boy verileri kullanılarak bazı populasyon parametreleri tespit edilmiştir. Boyca ortalama yıllık büyüme oranı 3.7 cm olarak bulunmuştur. Maksimum yaş dişiler için IX, erkekler için VI olarak tespit edilmiştir. Mevsimsel salınımlı von Bertalanffy boyca büyüme parametreleri; L„=39.1 cm, K = 0.15, to = -1.05, C=0.23, tj=0.48 olarak saptanmıştır. Erkek ve dişilerin büyüme oranları arasında farklılık olduğu; dişilerin erkeklerden daha hızlı büyüdükleri ve daha büyük maksimum boya ulaştıkları saptanmıştır. Toplam ölüm ve bileşenleri; Z=1.63, M = 0.39 ve F = 1.24 olarak belirlenmiştir. Trolle avlanabilecek en yüksek biyokütle değerinin, Doğu Karadeniz'de trol avcılığına kapalı bölge olan Çaltı Burnu-Sarp arasındaki alanda olduğu bulunmuştur. Trol avlarında en bol bulunan türün mezgit olduğu belirlenmiştir.

Öz:

Some population parameters of the whiting (Merlangius merlangus euxinus) distributed along the Turkish Black Sea coast, were determined by using age-length data. The mean annual growth rate in length was found to be 3.7 cm. The maximum age group was determined as IX for females and VI for males. The seasonalized von Bertalanffy growth parameters in length were estimated to be $L_infty$=39.1 cm, K = 0.15 $year^-1$, to = -1.53 year, C=0.23, $t_s$=0.48. There was a difference in growth rate between male and female fish. The females grow faster than males and reach a greater maximum length. Total mortality and its components were Z=1.63, M = 0.39 and F = 1.24. The highest trawlable biomass was found in the region between Çaltı Cape and Sarp which is an area closed to trawl fishing in the eastern Black Sea. In the trawl catches, the whiting was the dominant fish.
