Sažetak
The morphometric traits were determined on the sample of 459 marketable size common carp from the four Croatian fish farms. There traits were analyzed by the classical methods in order to determine the influence of population, scaliness, age and sex on the dressing percentage. The obtained results show the existence of different phenotypes of common carps at Croatian farms, primarily, morphometric differences. However, the sygnificant diferences of dressing percentage among the populations were not registered (p>0.05).
The significant difference between the dressing percentages of scaled and mirror carps was not detected (p>0.05), what leads to the conclusion that the scaliness does not influence dressing percentage significantly. The age and sex also, dit not show significant influence on dressing percentage. As the carps were sampled in winter the differences in dressing percentage caused by the different maturation of males and females were excluded.
