In this
study the length-weight relationships (LWRs) and length-length relationships
(LLRs) were determined of chub (Squalius cephalus
L., 1758) captured in the 15 different station of Karasu River. A total of
254 specimens were catched by electroshocker, gill nets, trammel nets between
October 2014 to September 2015. The length-weight relationships were determined
W=0.0069L3.19(R2=0.97)
for females, W=0.0061L3.26 (R2=0.98)
for males and W=0.0063L3.24
(R2=0.98) for all individuals. The types of growth for all
individuals were positive allometric for S. cephalus. Length-length relationships (LLRs) were determined as
TL=0.2423+1.0441FL; FL=0.0398+1.0957SL and SL=-0.2213+0.8694TL.
Bu çalışmada, Karasu Nehri’nin 15 farklı
istasyonundan yakalanan tatlı su kefalinin (Squalius
cephalus L., 1758) boy-ağırlık ve boy-boy ilişkileri belirlenmiştir. Ekim
2014-Eylül 2015 tarihleri arasında fanyalı ağları, uzatma ağları ve
elektroşoker ile toplam 254 örnek yakalanmıştır. Boy-ağırlık ilişkileri
dişilerde W=0,0069L3,19 3,19 (R2=0,97),
erkeklerde W=0,0061L3,26 (R2=0,98)
ve tüm bireylerde W=0,0063L3,24(R2=0,98) olarak tespit edilmiştir. S. cephalus’un tüm bireylerinde pozitif allometrik büyüme bulunmuştur.
Tüm bireylerde boy-boy ilişkileri TB=0,2423+1,0441ÇB; ÇB=0,0398+1,0957SB ve
SB=-0,2213+0,8694TB olarak bulunmuştur.
