Some population parameters of the Mediterranean horse mackerel [(Trachurus mediterraneus (Steindachner, 1868)] population living in Bandırma Bay, The Sea of Marmara

Abstract

A total of 1232 horse mackerel T.mediterraneus (Steindachner, 1868) were collected from Bandırma Bay, Sea of Marmara between September 2013 and December 2015 in order to evaluate some information on length-weigth frequencies, age-sex distribution and ratios, Von Bertalanffy growth equation, length-weight relationship, condition factor feeding of this species.  The population was composed of five age-classes (I-V) .Of 1232 specimens, female was of 33.87% and male % 66.13% with sex ratio as F:M=0,51: (p>0.05).  Total length and total weight of sampled fish ranged from 9.77 to 17.6 cm and 5.67 to 44.0 g., respectively.  Length-weight relationship and the von Bertalanfy growth parameter were estimated as W = 0.044L2.470, Lt=18.6[1-e0.24(t-3,3) ]), respectively.  Besides, growth performance index () of this species were determined as 4.4 for all individuals, As condition factor value was examined, it was determined that the highest value in CF reached in June.  The spawning period of T. mediterraneus  occurred between April and Eylül with a peak in July.  Absolute fecundity- total length relationship was estimated as F = 1.368xTL2.75.  It was estimated that total (Z) mortality , natural (M) mortality, and fishing (M) mortality rates were of  Z=1.36 year-1 ,M=0.33 yıl-1, F=1.03 yıl-1.  As exploitation rate was estimated as E=0.76, it can be said that the population was consumed highly.

Abstract

Bu çalışmada, Eylül 2013-Aralık 2015 yılları arasında Marmara Denizi balıkçılığında ekonomik yönden önemli olan sarıkuyruk istavrit populasyonunun boy ve ağırlık frekansları, boy-ağırlık ilişkisi, yaş ve eşey dağılımları, Von Bertalanffy büyüme eşitliği, kondisyon faktörü, gonadosomatik indeks, mortalite gibi bazı biyolojik özellikleri incelenmiştir. I – V yaş grupları arasındaki 1232 bireyin %33,87’ dişi, %% 66,13’ sı erkek olup, D:E=0.51:1 olarak bulunmuştur (p>0.05).  Boy- ağırlık ilişkisi ve büyüme eşitlikleri W = 0.044L2.470, Lt=18.6[1-e0.24(t-3.3) ]), =4.4 olarak hesaplanmıştır. Aylara göre kondüsyon faktörü değerleri incelendiğinde, ortalama en yüksek değere Haziran- ayında rastlandığı saptanmıştır.  T. mediterraneus populasyonunun üreme döneminin Temmuz ayında en yüksek değere ulaşarak, Nisan- Eylül ayları arasında olduğu belirlenmiştir.  Türün mutlak yumurta verimliliği-toplam boy F = 1.368xTL2.75 olarak tespit edilmiştir.  Toplam ölüm (Z), doğal ölüm, ve balıkçılıktan gelen ölüm oranı değerleri sırasıyla, Z= 1.36 yıl-1, M=0.33 yıl-1, F=1.03 yıl-1 olarak hesaplanmıştır. Sömürme oranı ise, E= 0.76 olup, populasyonun aşırı tüketildiği söylenebilir.
