Abstract
The present report deals with how the seasonal alteration of the living environment affects on phosphorus compounds content in gibel's muscle.
The results are shown in Fig. 1 and 2, and summarized as follows:
1) The content of high energy phosphorus compounds, such as creatine phosphate, adenosine di- and triphosphate, varied in accordance with seasonal rising and falling of the water temperature.
2) The reason why the gibel showed such remarkably high content of these high energy phosphorus compounds especially in August, September and October, was interpreted as preliminary accumlation in this period of the fat-like energy rich substances to be consumed during winter months (i. e. November, December, January and February), nonactivity period of this fish.
