抄録

The investigation was conducted on the size of a marine Chlorella cell exerted on the feed intake of Rotifers to obtain the following results.<BR>(1) The number of Chlorella cells did not almost increase during a light period but markedly increase during a dark period.<BR>(2) The average cell volume of Chlorella showed a large value of 10-18μm³ in the light period but became small in the dark period to show a value of 8-9μm³.<BR>(3) The average cell volume of Chlorella was 9.78μm³ when pH of culture water was 7.5-8.0 and 12.90μm³ when 9.0-9.5.<BR>(4) The feed intake quantity (cells/Rotifer/6 hr) of rotifers was 5200cells to Chlorella of 8μm³ and 8100cells to Chlorella of 12μm³.<BR>(5) When the average cell volume of Chlorella largely changed, the feed intake rate became lower and the maximum feed intake rate was 52.8% when the change rate was 106%.<BR>(6) The size of Chlorella always changed in a culture tank for the culture of rotifiers in the presence of Chlorella and it was considered that the feed intake rate of Chlorella, which had a proper size for rotifers, and a change rate of 106% was highest.<BR>(7) The density of rotifers and the average cell volume of Chlorella were participated in the feed intake quantity of Chlorella.
