  1. 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 % 。
  2. Only the water at jiekou had been eutrophic. the result of biological assessment was that the average density of phytoplankton at all the sampling spots was more than 1, 000, 000 per litre, indicating that the lake was eutrophic going by the population density. but this density of phytoplankton was higher than that in similar lakes at the same pollution level

    生物評價結果認為，千島湖浮遊藻類平均密度較同類營養水平的淡水水體高，其所有取樣點浮遊藻類平均密度都10 ~ 6個? l ，國內外一般認為當浮游植物平均密度10 ~ 6個? l時，其已經達到富營養化水平，因此單從浮游植物密度來看，可以認為千島湖已達到水體富營養化。
  3. Effects of size structure and pigment composition of algal population on phytoplankton absorption coefficients in the south china sea
