Abstract: By means of spectrophotometric method, the Authors observed daily variations of pigment amounts in natural plankton collections for 100 days (from April 20 to July 31), coinciding with the season of phytoplankton blooming, at Sakibe Inlet in Sasebo Bay.In the usual case, the rate of daily variations of E435, were less than 2.0 times or more than half in the increase-or decrease-curves, respectively (Fig. 1), but in the unusual, there seemed possibility of exceeding those.During the observation period, the maximum rate was 3.5 times or 1/8 time in the increase-or decrease-curves, respectively.Hence, we must keep, there being more wide variation of pigment amount in the field, in minds.Under these circumustances, the Authors assumed to be appropriate twice a week as sampling interval from the data collected.
