Abstract:
The “Klosi Fish-Breeding Farm”, Elbasan was chosen as a suitable place for studying of several phenotypes of species of Cyprinus carpio L in central part of Albania. During the breeding seasons on period 2012 – 2013 were studied frequencies type of scales in “frys” and” fingerlings” of carp (common carp) (Cyprinus carpio L.) and was also estimated impact of their phenotype characteristic on survival parameters. Here are presented some preliminary result of the study. Thus, we have proved that 81. 6% of Frys (total 16, 524 individuals) represents the phenotype “scaled”and Frequency of Frys with phenotype “linear mirror” was 9. 4% (1904 individuals). Fingerlings with phenotypes “leather mirror” and “scattered “are encountered with respective frequency 4. 1% and 4. 9% (830 and 992 individuals). We also, can show that, the presence of phenotype “scaled distributed” (genotype ssnn) of Fry is related by artificial reproduction of genotype Ssnn. Some other parameters were: The highest value of survival characteristic was detected for “Scaled” phenotype of fingerlings species (80. 99%). Phenotype “linear mirror” of carp fingerlings represents a value of survival 65. 02%. The respective value of survival in fingerlings stage, for “leather mirror” and “scaled distributed” phenotype of carp were 60. 96% and 76. 01%. The greater average value of weight of “Scaled ” phenotype of fingerlings were 44, 535 ± 4, 149 g. The smallest average value of weight (31, 395 ± 2, 032 g) was observed for fingerlings with “Linear mirror ” phenotype. As result, we can prove that, fingerlings breeding of different types of carp in semi-intensive system represented with different value of growth, and “scaled” phenotype represents dominant to other phenotypes.
