Growth, the length-weight relationship, and reproduction in vimba (Vimba vimba L. 1758) sampled from an oligo-mesotrophic lake in northwest Anatolia (Turkey)

Temmuz 2003-Eylül 2004 tarihleri arasında Sapanca Gölü’nden aylık olarak yakalanan eğrez balığının (Vimba vimba L. 1758) büyüme parametreleri ve üreme periyodu belirlenmiştir. Yakalanan 335 eğrez balığının yaş değerleri 2+ ve 6+ yaşları arasındadır ve çoğunluğu 4+ yaşındaki bireylerden oluşmaktadır. Boy-Ağırlık ilişkisi erkekler için W = 0,0084 FL3,1797±0,0035 (r2 = 0,94, P < 0,05) ve dişiler için W = 0,0089 L3,1572±0,0033 (r2 = 0,93, P < 0,05) idi. Cinsiyetler arasındaki regresyon katsayısı önemlidir (t-test, P < 0,05). “b” değeri aylara göre önemliydi (ANCOVA, P < 0,05). Dişi ve erkek eğrez balıklarının “b” değeri 3’ten büyüktür ve pozitif allometrik büyüme göstermektedir. von Bertalanffy büyüme eşitliği erkeklerde; Lt=28,940 (1-exp {-0,123[t+2,193]}), ∅’: 2,030, (r = 0,999) ve dişilerde Lt = 24,708 [1-exp {-0,205[t+1,464]}), ∅’: 2,097, (r = 0,999) olarak belirlenmiştir. Cinsiyet oranı 1:1,86’dır (χ2; P < 0,05). Eğrez balığının yumurtlama periyodu Nisan sonunda başlamakta ve Temmuz başına kadar devam etmektedir. Bu dönemdeki su sıcaklığı 14,8 ile 25,4 °C arasındadır.

Kuzeybatı Anadolu’da oligo-mezotrofik bir gölde eğrez (Vimba vimba (Linnaeus 1758)) balığının büyümesi, boy-ağırlık ilişkisi ve üremesi

The growth parameters and reproduction period in vimba (Vimba vimba L. 1758) sampled from Sapanca Lake were determined monthly between September 2003 and July 2004. The 335 vimba specimens caught ranged in age from 2+ to 6+ years, and the majority of the samples consisted of individuals of the 4+-year-old age group. The length-weight relationship was estimated to be W = 0.0084 FL3.1797±0.0035 for males (r2 = 0.94, P < 0.05) and W = 0.0089 FL3.1572±0.0033 for females (r2 = 0.93, P < 0.05). Regression coefficients for sex were significant (t-test, P < 0.05). The slope (b) significantly differed (ANCOVA, P < 0.05) between months. The fact that the b values for male and female vimba specimens differed from 3.0 indicates that there was positive allometric growth. The von Bertalanffy equation was determined using Lt = 28.940 (1-exp {-0.123[t+2.193]}), ∅’: 2.030, (r = 0.999) for males and Lt = 24.708 [1-exp {-0.205[t+1.464]}), ∅’: 2.097, (r = 0.999) for females. The sex ratio was 1:1.86 (χ2; P < 0.05). The spawning period of vimba began at the end of April and continued until the beginning of July; the water temperature during this period was between 14.8 and 25.9 °C.
