A study on bacteria attached to suspended particles in shrimp ponds

Fisheries College of Ocean University of Qingdao, Qingdao 266003

摘要

摘要: 用5个实验围隔研究了对虾池悬浮颗粒上的附着细菌,结果表明:附着细菌数量波动在0.65×10⁴～23.49×10⁴个/cm³之间,平均为(4.57±3.64)×10⁴个/cm³,占水体细菌总数的1.47%×1.41%(0.28%～8.73%).附着细菌数为1、2、3、4个的附菌颗粒占总附菌颗粒的比数分别为40%、27%、15%及11%,多于4个附着细菌的附菌颗粒数仅占总附菌颗粒数的7%;总悬浮颗粒中的附菌颗粒所占比例为52%;附着细菌数与水体总悬浮颗粒数关系最为密切,与水温及总细菌数也具有显著相关性,但与水层POC及DOC含量却未呈现显著的相关性.

Abstract: Bacteria attached to suspended particles in shrimp ponds are studied with five experimental enclosures and several important results are obtained.The number of those bacteria fluctuated between 0.65×10⁴ and 23.49×10⁴ ind /cm³, averaged (4.57×10⁴±3.64×10⁴) ind ·/cm³, and is 1.47% (0.28%～8.73%) of the total bacteria.The number of particles which atcached by 1,2,3 and 4 bacteria is 40%,27%,15% and 11% of the total particles attached by bacteria, respectively.The number of particles which attached more than 4 bacteria is only 70a of the total particles attached by bacteria. The percent of particles attached by bacteria is 52% to the numbers of total particles. There is an obvious correlation between the number of bacteria attached to particles and the number of total particles.The number of particle-bound bacteria is correlated positively with water temperature and the total number of bacteria, but is not rnrrelated with POC and DOC.
