“…The basic nutrient values obtained in this study are similar to those reported in 2003 for fillets with skin of four strains of carp 14 and with data from 2005 for muscle of 3-old-year carp of five strains 15 . The water percentage decreases, and the fat and protein percentages increase, with increasing body weight and length, whereas the ash percentage remains fairly constant.…”

Consumer protection against food adulteration and misleading labelling is integrated into EU legislation, but accurate analysis of the meat content of farmed freshwater fish products is not possible because of the lack of established nitrogen factors for farmed common carp. The aim of this study was to determine nitrogen factors for farmed common carp Cyprinus carpio. Seven-hundred samples collected in 2018–2019 in three harvest seasons (March/April, Jun/July, and October/November) at seven locations in the Czech Republic were analysed for nitrogen, dry matter, protein, ash, and fat content according to standard ISO methods. The recommended nitrogen factor for fat-free common carp fillet with skin is 3.04 ± 0.13 and, for fillet without skin, 2.95 ± 0.12. Availability of nitrogen factors for common carp can help ensure that consumers are purchasing correctly labelled products.

“…The nutritional composition of fish muscle is influenced by many factors such as fish species, age, gender, rearing conditions, breeding technology, and season, etc. (Fajmonova et al 2003;Buchtova et al 2008Buchtova et al , 2010Adeniyi et al 2012).…”

Measures for consumer protection against food adulteration and misleading labeling are integrated into EU legislation, including methods for detection of misleading practices. Verification of meat content is available for marine products but not for freshwater fish because of the lack of standard nitrogen factors. The aim of this study was to establish nitrogen factors for European pike-perch Sander lucioperca (Linnaeus, 1758), northern pike Esox lucius Linnaeus, 1758, and sheatfish Silurus glanis Linnaeus, 1758. The study involved analysis of 808 fillet samples obtained in spring (March–April) and autumn (October–November) harvest seasons, 2018–2019, from seven Czech Republic fish rearing facilities. Samples with and without skin were analyzed for nitrogen content, dry matter, protein, ash, and fat according to established ISO methods. The recommended nitrogen factor for European pike-perch with the skin is 3.28 ± 0.09 and without the skin is 3.21 ± 0.09; for northern pike with the skin is 3.18 ± 0.09 and without skin is 3.15 ± 0.09; and for sheatfish with skin is 2.73 ± 0.13 and without skin is 2.75 ± 0.12. The established nitrogen factors will enable analysis of meat content to ensure that consumers are purchasing correctly described and labeled fish products.

“…Likewise, TAG values were higher in females of all tested breeds compared with males (significantly in AS, US, M72, and M2). We propose that this may be the result of the difference in lipid content between ovary and testes (Buchtová et al., 2008). Idler and Bitners (1960) found that a portion of the lipid reserves is transferred to gonads of Oncorhynchus nerka during maturation; about 8% is transferred to the female gonad and 0.5% to the male gonad.…”

Eight breeds of common carp (Cyprinus carpio L.) spawners reared under identical conditions and sampled in spring after over-wintering were examined in order to compare their basic biochemical blood profiles. The breeds compared were: Amur wild carp (AS), Ropsha scaly carp (ROP), Ukraine scaly carp (US), Northern mirror carp (M72), South Bohemian mirror carp (BV), Israeli mirror carp (Dor 70), Hungarian mirror carp (M2) and Tata scaly carp (TAT). Significant differences were found among breeds in glucose concentration (GLU), total protein concentration (TP), triacylglycerols concentration (TAG), and calcium (Ca) and phosphorus (P i ) concentration. No differences were observed in aspartate transaminase activity (AST) or alanine aminotransferase activity (ALT). The highest glucose, total protein, and calcium (Ca) concentrations were found in AS (GLU 8.3 ± 1.2 mmol L )1 , TP 32 ± 3 g L )1 , Ca 2.42 ± 0.22 mmol L )1 ). High values of triacylglycerol concentration (TAG) were found in ROP (1.94 ± 0.52 mmol L )1 ). Phosphorus (P i ) concentration was highest in M2 (3.82 ± 1.34 mmol L )1 ). Amur wild carp and breeds originating therefrom (ROP, US, and M72) had significantly higher values of TP (P < 0.05), TAG (P < 0.05), and Ca (P < 0.01) and significantly lower values of P i (P < 0.05) than did the other breeds. Scaly breeds had higher values of glucose (P < 0.01), TP (P < 0.01), ALT (P < 0.01), and Ca (P < 0.01) and significantly lower values of P i (P < 0.01) than did mirror carp. Significant (P < 0.01) sex-related differences were found in GLU, TAG and Ca concentrations.
