In order to demonstrate the variation with season and growth in nitrogenous extractives of dark-fleshed fishes, free amino acids, trimethylamine oxide, creatine, creatinine and nucleotides in the dorsal muscle of mackerel were determined.
The following are evident in the present analyses (Table 2-4).
1) The mackerel caught in spawning spring contained smaller amounts of extractive nitrogen, free histidine and creatine than the fish in winter.
2) In the small-sized mackrel, lower contents of extractive nitrogen and free histidine were found than in the large-sized one.
These variations in the extractive constituents are schematically shown in Fig. 1.
