Özet
The effect of supplemental feeding with modified cereals (pressed triticale, barley, rye and pressed wheat in combination with rape) on the growth of common carp was studied under semi-intensive pond farming conditions. Non- pressed triticale, barley and rye were used for comparison. Two groups were selected as a control dependent only on natural zooplankton. For the evaluation, we employed five models designated M1 linear mixed models with a random intercept; M2 linear mixed models with a random slope; M3 a linear mixed model with a random intercept and slope; M4 written as model M3 with a power variance function, where the error variance was modelled and M5 written as model M4 with a power variance function, with a different model of error variance. Model M5 took heterogeneous errors with respect to differing strata. Common carp that were fed supplements of modified cereals showed a significant lower variability of weight (lower SD and narrower 95% CI) compared to the non-pressed diets and pressed barley and rye that yielded higher production. These results suggest that pressed cereals increase yield in commercial production of common carp under semi- intensive conditions.
