title: Tissue polyamine concentrations in the European sea bass (Dicentrarchus labrax L.): change with age and season of the year.
abstract: Independently of the age of the European sea bass, putrescine and spermidine are much higher in liver and brain than in muscles, while spermine concentrations are more similar to one another. The polyamine concentrations are higher in 2 years old sea bass than in 1 year old fish except for heart spermidine and liver spermine. Lowering in water temperature causes a decrease in the concentration of spermidine and spermine in all tissues examined. Putrescine, however, increases in heart, caudal muscle, liver and brain and it is unchanged in red and dorsal muscles.
