But the gut evacuation rates did not vary with the experimental temperature and body size. copepods usually performed feeding rhythms with maximum level at midnight and their feeding activities changed with the tide rhythms at the estuary area. in the laizhou bay, the daily grazing rate of the copepod population on phytoplankton was 20. 81 ? 98. 35 % of the primary production and 2. 53 ? 6. 36 % of the phytoplankton standing stock in summer
現場測得的橈足類攝食率結果表明，在萊州灣，夏季橈足類群體的日攝食量占初級生產力的20 . 81 ? 98 . 35 % ，占浮游植物現存量的2 . 53 ? 6 . 36 % ，濰河口，河口外浮遊動物優勢種群體的日攝食量占初級生產力的32 . 28 % ，占浮游植物現存量的14 . 12 % ，河口內對初級生產力的攝食壓力< 3 % ，日攝食量小於浮游植物現存量的1 % 。 -
