| description | A crucial element in improving aquaculture performance, including the crayfish farming sector, is enhancing and developing cultivation technologies for new species, whose potential can rapidly supply the market with commercial products. This study aimed to analyse the impact of dietary modifications on the growth performance of Procambarus clarkii when fed a vitamin-amino acid complex, “Chicktonic”, at rates of 1.0 mL/kg (Group 2) and 2.0 mL/kg (Group 3). The study employed theoretical (analysis, systematisation, comparison), experimental (laboratory), and standard aquaculture research methods. Results indicated that crayfish fed diets supplemented with “Chicktonic” exhibited higher growth rates throughout the experimental period. For instance, Groups 2 and 3 demonstrated a 3.9 and 4.3-fold increase in weight, reaching 13.70 ± 1.10 g and 16.24 ± 1.30 g, respectively. In the control Group 1, which received feed without the vitamin supplement, the lowest weight gain was recorded, increasing by a factor of 3.7, reaching 13.93±1.89 g by the end of the study period. No significant differences in body length were observed among all groups; however, in experimental Group 3 (2.0 mL/kg), this indicator was 8.34±0.22 cm, compared to 7.83 ± 0.42 cm in Group 1 and 7.83 ± 0.18 cm in Group 2. It was found that the introduction of the vitamin-amino acid supplement into the crayfish diet accelerated the sexual maturation of females in experimental Groups 2 and 3, where the first specimens with eggs were recorded. The effect of vitamin intake was also noted in the visual assessment of the colour of the crayfish’s external chitinous covering. Group 3 (2.0 mL/kg) exhibited a bright red hue, whereas the control group had a pale red, sometimes pale orange, carapace colour. The results obtained may be used to optimise the artificial cultivation of Procambarus clarkii and suggest the use of vitamin supplements to improve their welfare and well-being |
