Abstract: This study was conducted to evaluate the adaptability of the hybrid mirror carp strain ALxDOR70 (Mirror) from the University of Bohemia in the Czech Republic. Larvae were injected into three ponds. The Bubiai carp larvae (Scaled) were also injected into the same ponds as the control group. Twenty-five thousand larvae of both carp varieties were injected into each pond. The initial mean weight of injected larvae was 4 mg. Measurements started from autumn 2020 to spring 2022. Fish measurements were carried out in the autumn and spring seasons, like a routine of fish farms. Length-weight relationship, Fulton's condition factor (KF) and Relative condition factor (KR) from standard length (L) and body weight (W) were analysed in different years and seasons. The results suggest that the lengths and weights of Scaled carp were lower than those of Mirror, and these differences were statistically significant (P <0.05) throughout the study. The values of the coefficient of determination r2 between the length and weight ratio for both species were determined to be significant (r2 > 0.60, P < 0.001). A weaker but significant relationship was obtained in autumn 2021 for Mirror carp (r2 < 0.59).
Cube law results showed that the regression coefficient b < 3.0 was obtained for both studied species, although a higher value of b was obtained for Scaled carp throughout the study period. Average values of Fulton's and relative condition factor were obtained higher than 1 in every season, reflecting good living conditions. At the same time, Mirror carp adapted well enough to live in new conditions. Survival in autumn 2020 and spring 2021 was better for Mirror carp than Scaled, but in autumn 2021 and spring 2022, better survival rates were obtained for Scaled carp. It was concluded that there was a significant difference in survival, growth parameters, length, weight, and condition factors between Scaled and Mirror carp in different seasons. The results obtained in the study can be used to understand the frameworks related to domestication and management for the adaptation of new carp breeds and breeding in fish farms.
