| 摘 要： | 1997年6～8月于山东省海阳市黄海集团公司养虾场,用5个实验围隔研究了对虾池不同粒级浮游生物的呼吸率和初级生产率.结果表明:(1)小型、微型及超微型浮游生物的呼吸率平均分别为0.07,0.38及0.31mg/(dm3·d),占各粒级浮游生物总呼吸率的9%,50%及41%.小型、微型及超微型浮游植物的生产率平均分别为0.04,1.26及0.15mg/(dm3·d),占相应粒级浮游植物总生产率的3%,87%及10%.各粒级浮游生物呼吸率占相应粒级浮游植物生产率的比例为:小型浮游生物175%;微型浮游生物30%;超微型浮游生物207%.(2)小型浮游动物、超微型浮游动物(含细菌)的呼吸率显著高于相应粒级浮游植物呼吸率,微型浮游植物的呼吸率明显高于微型浮游动物呼吸率.不同粒级浮游植物呼吸率的大小顺序为微型、超微型、小型,不同粒级浮游动物呼吸率顺序为超微型(含细菌)、微型、小型.

| Abstract: | Size-fractionated plankton respiration and phytoplankton production rates in shrimp culture ecosystems were studied with five experimental enclosures from June to August 1997 in the shrimp farm of the Huanghai Fisheris Corporation in Shandong Province,China.The results show that(1) the average respiration rates of the plankton of micro-,nano- and pico-plankton are 0.07,0.38 and 0.31 mg/(dm3·d),which are 9%,50% and 41% of the sum of each sized plankton.The phy toplankton production rates of micro-,nano- and pico-phytoplankton are 0.04,1.26 and 0.15 mg/(dm3·d),which are 3%,87% and 10% of the sum of each sized phytoplankton.The ratios of the respiration rates of different sized plankton to corresponding sized phy to plankton production rates are:micro-,175%;nano-,30%;pico-,207%.(2) the respiration rates of zooplankton of micro-and pico-(containing bacteria) are higher than those of the corresponding sized phytoplankton,while the respiration rate of nano-phytoplankton is higher than that of nano-zooplankton.The sequence of the respiration rates of different sized phytoplankton is nano-greater than pico-greater than micro-,and the order of the respir ation rates of different sized zooplankton is pico-(containing bacteria) greater than nano-greater than micro-. |
