【摘要】 1997年 6～ 9月在山东省海阳市黄海水产集团养虾场 ,采用围隔实验生态学方法研究了对虾养殖生态系浮游动物对细菌的摄食作用。结果表明 :浮游动物对细菌摄食量为 98～643μg C· dm- 3· d- 1,平均为 ( 2 62± 1 67)μg C· dm- 3· d- 1。浮游动物对细菌摄食量为细菌生产量的 73%～ 1 75% ,平均为 ( 1 1 3± 31 ) %。小于 3μm的浮游动物对细菌摄食量占浮游动物对细菌总摄食量的 1 7% ,其它规格浮游动物 ( >3μm)摄食量占 83%。更多还原

【Abstract】 Zooplanktoon feeding on bacteria of shrimp cultural enclosure ecosystems was studied from June to September, 1997 in the shrimp farm of Huanghai Fisheries Group Corporation. The results showed that the amount of bacteria fed by zooplankton was 98～643μgC·dm -3 ·d -1 with an average of (262±167)μgC·dm -3 ·d -1 . The amount of bacteria fed by zooplankton was 73%～175% of the production, averaging (113±31)%. The portion of bacteria fed by zooplankton smaller than 3μm was 17 percent of the amount fed by the total zooplankton, and the rest was fed by zooplankton of other sizes (>3μm).更多还原
