    Karakaya Baraj Gölü Bazı Balıklarının Kan Serum Proteinlerinin Elektroforetik Modelleri Üzerine Taksonomik Bir Çalışma
    (Selçuk Üniv. Vet. Bil. Derg, 2000) Yılmaz, Muhittin; Türköz, Yusuf; Erdemli, A. Ümit; Kalkan, Ercan; Çiğremiş, Yılmaz
    In Ihis study, an electrophoretic comparison 01 serum blood proteins of two species 01 fish, Cspoeta trulla and Capoels capoeta umbls, were carried out. Study was carried between june and october in 1997. Using the Ran· dom Sampling Method, 92 C. capos's umbla and 86 C. trutta which the same age and sex were used. The iden· dification of species and subspecies were done though their metric and meristic characteristics. While 16 band pat· tern was observed in C. trutta, the number 01 protein bands for C. capoeta umbla was 11 . From the electrophorelic mobility 8 bands of species gave similar pattern, but the rest was seen to be different. As a result, we concluded that, there is a %50 similarity between C. trulta and C. capoeta umbla based on their serum blood proteins.

    Some Biological Properties of Leuciscus cephalus (L., 1758) Population Living in Karakaya Dam Lake at Malatya, Turkey
    (Turkish Journal of Veterinary and Animal Sciences, 2005) Kalkan, Ercan; Yılmaz, Muhittin; Erdemli, A. Ümit
    The sex distribution, growth in length and weight, growth rates and condition factors of Chub (Leuciscus cephalus (L., 1758)) in Karakaya dam lake were examined. Females made up 63.64% and males 36.37% (1.75:1) of 527 samples. The females and males were in the I-VI and I-V age groups, respectively. The reproductive properties of L. cephalus such as spawning period, age at attainment of maturity, egg diameter and ovarium weight were investigated. StudentÕs t test showed that differences in length and weight between females and males of the same age groups were statistically insignificant (P > 0.05). The growth, both in length and weight, was calculated according to the von Bertalanffy equation for females and males respectively: Lt = 37.8 [1-e-0.4125(t-(-1.0013))], Wt = 775.3 [1-e-0.4125(t-(-1.0013))]3.0272 and Lt = 35.45 [1-e-0.6062(t-(-0.1883))], Wt = 590.5 [1-e-0.6062(t-(-0.1883))]2.4878. The calculated length-weight relation for females was W = 0.013 L 3.0272 and for males W = 0.0824 L2.4878. The average condition factor was 1.42 ± 0.05 for females and 1.43 ± 0.25 for males. According to gonado-somatic index (IG) results and the development of egg diameter, it was determined that the spawning period of L. cephalus occurs in May and June. Sexual maturity was attained in the third year. The mean diameter of ripe eggs was 1.06 mm and the mean number of eggs per gram of gonads was 1265.
