“…In rainbow trout juveniles fed a dipeptide-based diet devoid of proline, endogenous synthesis did not maintain proline levels comparable with fish fed diets with proline [casein(+/-)]. The free proline levels in muscle of the dipeptide-fed group are at the lower end of the range reported in fish muscle (Torrissen et al, 1994;Yamamoto et al, 2000;Ogata, 2002). In large rainbow trout fed a low-protein, 5% casein-containing diet, only 'trace' amounts of free proline were found in muscle, whereas in fish on a 50% casein diet, the proline concentration was 3400·μmol·kg -1 (Yokoyama and Nakazoe, 1991).…”

“…Diets were isonitrogenous and isolipidic and contained either (1) casein-gelatin as the protein source ['casein' diets, with (+) or without (-) inclusion of maca meal; Lee et al, 2004], (2) a mixture of synthetic dipeptides ('dipeptide' diet) or (3) a mixture of synthetic amino acids ('Free AA' diet). The levels of amino acids in the experimental diets (g·100·g -1 ) were calculated from added amounts (Dabrowski et al, 2003) (Kim et al, 1992;Berge and Storebakken, 1996;Yamamoto et al, 2000;Halver, 2002). All diets covered the requirements for IDAA in rainbow trout (NRC, 1993).…”

SUMMARY The premise that a dietary dipeptide approach will improve the understanding of amino acid utilization in the fastest-growing vertebrate, the teleost fish, was tested by examining the muscle free amino acid (FAA) pool and enzyme activities, in concert with growth response, when dietary amino acids were provided in free, dipeptide or protein molecular forms. We present the first evidence in fish that, in response to a synthetic dipeptide diet,muscle FAA varies as a result of both growth rate and amino acid availability of specific peptides. We demonstrate significantly diminished muscle indispensable FAA (3–10-fold) in rainbow trout alevins fed a dipeptide-based diet compared with a protein-based diet. The dipeptide-based diet did not contain proline, resulting in 10–27-fold less muscle free proline and hydroxyproline in alevins. The response of alevins fed FAA-based or peptide-based diets can be indicative of collagen turnover (Hyp/Pro ratio)and showed significant differences between dietary treatments. Pyrroline-5-carboxylate (P5C) reductase activity was detected, suggesting that P5C may ameliorate proline deficiency, but synthesis from glutamate could not maintain free proline levels in muscle. This finding will provide an impetus to test whether proline is conditionally indispensable in young fish, as in mammals and birds. This study shows that amino acids given entirely as dipeptides can sustain fish growth, result in muscle FAA and enzyme responses in line with dietary levels and identify growth-limiting amino acids. The understanding of these factors necessitates a diet formulation that will improve the accuracy of determining amino acid requirements in the early life stages of vertebrates.

The aim of the study was to determine the amino acid composition in fillet proteins of newly bred mirror carp lines. In the experiments, the Hungarian mirror carp (M2) were used at the maternal position. These were crossed with male carp of other breeds (top crossing). They included the Hungarian mirror carp (M2) for the production of a pure line, the Hungarian mirror line (L15), the Israeli breed (DOR70) and the Northern mirror carp (M72). The scaly hybrid of the Ropsha (ROP) and the Tataj (TAT) carp was used as a control. In view of the genetic specification of the carp groups monitored, numerous differences (P  0.01 and P  0.05) in the composition of specific amino acids (EAA: Val, Leu, Lys, Arg, Met NEAA: Asp, Glu, Tyr) and their total amounts (EAA sum , NEAA sum ) were found between the scaly control (ROP × TAT) and the pure line M2. Higher amino acid values were found in control hybrids. Compositions of amino acids in fillet muscle tissue of experimental mirror carp (M2 × L15, M2 × DOR70) were practically identical. Compared to the controls (ROP × TAT), these carp groups contained less (P  0.01) Leu, Lys, Arg and Glu. A composition of amino acids statistically comparable with the controls (ROP × TAT) was found only in the M2 × M72 hybrid with the exception of Glu, which was found in smaller quantities in this hybrid (P  0.01). In terms of sex differences, the greatest amounts of amino acids were found in fillets of male ROP × TAT controls, the amino acid compositions in male and female mirror carp were practically the same. In this type of evaluation, i.e. regarding amino acid composition, the only carp comparable with the ROP × TAT control is the M2 × M72 hybrid. Fish meat, carp, amino acid, chemical indicator, qualityIn the Czech Republic, the common carp (Cyprinus carpio, Linnaeus 1758) of the family Cyprinidae is considered as economically the most important fresh-water fish species reared for commercial purposes. Typically extensive to semi-intensive in character, carp production is based on the farming of F1 generation fry obtained from controlled reproduction of sexually mature genetically specified generation carp. The breeds of mirror carp used in the Czech Republic for this purpose are of the original Hungarian line denominated as M2, or a hybrid between M2 and the Northern Mirror Carp breed referred to as M72 (Czech origin). In scaly carp, the most frequent generation fish is the Třeboňský scaly carp, Mariánsko-Lázeňský scaly carp (both breeds of Czech origin), or a hybrid between the Ropsha carp (ROP) of Russian origin and the Tataj carp (TAT) of Hungarian origin. Production of carp at smaller fish farms relies also on the fry from local carp populations that have been given names derived from the nearby villages or locations, and which are often not unambiguously genetically specified. Carp production utilizes natural foods supplemented with cereals and complementary feed mixes.Carp breeding receives systematic attention with the objective to enhance useful characteristics and pro...

“…Yamamoto et al (25) observed that tissue free amino acid levels in fingerling rainbow trout (Oncorhynchus mykiss) were affected by dietary fat levels. The levels of asparagine, glycine, methionine, tyrosine, and phenylalanine were significantly higher in the dorsal white muscle of rainbow trout fed low-protein diets with a balanced amino acid diet+high fat diet, as compared to rainbow trout receiving low-protein diets with a balanced amino acid diet+low fat diet.…”

The present research was aimed at a comparative analysis of free amino acid (FAA) levels in the muscle tissue of herbivorous and predatory fish. The FAA concentration in the muscle tissue samples from bighead carp and wels catfish was determined by ion-exchange chromatography. The bighead carp muscle tissue, as compared to that of wels catfish, showed significantly higher concentrations of arginine, histidine, methionine, phenyloalanine, alanine, asparagine, serine, glycine, and taurine, but significantly lower levels of isoleucine, leucine, threonine, valine, glutamine, cystationine, β-alanine, ethanoloamine, as well as aspartic, glutamic, cysteic, α- and γ-aminobutyric acids. The muscle tissues of bighead carp and wels catfish did not differ significantly in the levels of cystine, lysine, tryptophan, tyrosine, α-aminoadipic acid, cytrulline, ornithine and 1-methyl-histidine. Proline was detected only in the wels catfish muscle. The results obtained have shown differences in free amino acid concentration in muscle tissue of examined fish. A differentiated natural diet induces changes in free amino acid content in fish tissues. Knowledge of levels of free amino acids which are precursors for biogenic amines facilitates setting the safety criteria for fish and fishery products from species other than those mentioned in the Commission Regulation No 2073/2005
