In the previous report, it was pointed out that the content of various kinds of phosphorus compounds in fish muscle varied with the seasonal change of water temperature. In this report, it was investigated, by using gibel and mebaru, a kind of rock fish, whether the phenomenon mentioned above can also be seen when the fish were reared at different water temperatures.
The results obtained are shown in Fig. 1, 2 and 3, and can be summarized as follows;
1. In the preliminary experiment, the adaptation of fish to widely varied water temperature was accomplished by changing gradually the water temperature.
2. When the fish were reared at the water temperature suitable for their living, high energy phosphorus compounds content in muscle increased. On the other hand, when the water temperature fell remarkably, the total amount of phosphorus in acid soluble fraction in fish muscle diminished in parallel with the decrease of high energy phosphorus compounds content.
