Length based growth estimates and reproduction biology of whiting, merlangius merlangus euxinus (Nordman, 1840) in the southeast Black Sea
Öz: Mezgit balığının, Merlangius merlangus euxinus, büyüme şekli ve üreme biyolojisi güneydoğu Karadenizde Nisan 2011 ve Mart 2012 tarihleri arasında çalışılmıştır. Aylık boy frekans dağılımından hesaplanan mevsimsel von Bertalanffy büyüme denklemi parametreleri erkekler için L∞ = 18,95 cm TL, K = 0,900 yıl-1, dişiler için L∞ = 20,29 cm TL, K = 0,805 yıl-1 olarak hesaplanmıştır. Erkeklerin (C = 0,510) büyümesindeki mevsimsel salınım dişilerden (C = 0,197) daha güçlü olup, büyümenin en yavaş olduğu dönem, erkeklerde Mayıs ayına (WP = 0,358) dişilerde ise Ocak ayına (WP = 0,040) karşılık gelmiştir. Yumurta verimi 11659 ve 354204 arasında değişmiş (ortalama 70.919±11.659 yumurta), yumurta verimiyle toplam boy arasındaki ilişki istatistiksel olarak sıfırdan farklı bulunmuştur (P<0,0001). Gonadlardaki büyüme 1. safhadan 4. safhaya kadar yıl boyunca devam etmiş, her iki cinsiyet için henüz boşalmış gonalar Ağustos, Aralık ve Ocak aylarında tespit edilmiştir. Yumurtlama yıl boyunca devam etmiş, yoğun şekilde yumurtlama ise yaz sonunda, sonbahar ortasında ve kış başında olmak üzere yılda en az üç kez gerçekleşmiştir. Cinsi olgunluk boyu dişiler için 14,6 cm TL, erkekler için ise 19,9 cm olarak hesaplanmıştır. Üreyen balığın korunması ve mezgit dip uzatma solungaç ağlarıyla sürdürülebilir bir mezgit balıkçılığı için asgari yakalama boyunun 15 cm TL olarak uygulanması önerilmiştir.

Öz: Growth pattern and reproductive biology of whiting, Merlangius merlangus euxinus were studied in southeast Black Sea between April 2011 and March 2012. The seasonal von Bertalanffy growth equation parameters, computed from monthly length frequency distributions, were estimated as L∞ = 18.95 cm TL, K = 0.900 year-1 for males and as L∞ = 20.29 cm TL, K = 0.805 year-1 for females. Seasonal oscillation of growth for males (C = 0.510) were stronger than females (C = 0.197), and the time of the slowest growth period corresponded to May (WP = 0.358) in males and January (WP = 0.040) in females. Fecundity ranged between 11659 and 354204 eggs (mean 70,919±11,659 eggs) and fecundity - total length relationship was significantly different from zero (P<0.0001). The growth of gonad from stage 1 to stage 4 appeared throughout the year and recently spent gonad was also observed only in August, December and January for both sexes. Spawning continues throughout the year with intensive spawning occurred at last three times in a year; at the end of the summer, in mid-autumn and in early winter. The size at sexual maturity was estimated as 14.6 cm TL for females and 13.9 cm for males. The protection of whiting breeding and for a sustainable whiting fishery with bottom gill nets, the smallest capture size should be applied as 15 cm TL.
