The metabolic response in fish to mildly elevated water temperature relates to species-dependent muscular concentrations of imidazole compounds and free amino acids
Fish species show distinct differences in their muscular concentrations of imidazoles and free amino acids (FAA). This study was conducted to investigate whether metabolic response to mildly elevated water temperature (MEWT) relates to species-dependent muscular concentrations of imidazoles and FAA....

Fish species show distinct differences in their muscular concentrations of imidazoles and free amino acids (FAA). This study was conducted to investigate whether metabolic response to mildly elevated water temperature (MEWT) relates to species-dependent muscular concentrations of imidazoles and FAA.

Although the sum of imidazole (HIS +NAH) and TAU in muscle remained constant over species and temperatures (12 > 0.05), (NAH+HIS)/TAU ratio was markedly higher in carp versus tilapia, and decreased with MEWT only in carp (P < 0.05). Many of the muscular FAA concentrations were higher in carp than in tilapia (P < 0.05). Plasma acylcarnitine profile suggested a higher use of AA and fatty acids in carp metabolism (P < 0.05).
