有机污染提高双壳贝类对弧菌易感性的研究↑（*）

在实验室条件下，通过投饵不换水所形成的有机污染来研究有机污染提高双壳贝类对弧菌的易感性。结果表明，有机污染时间越高长，弧菌的浓度越高；弧菌的数量与有机污染环境中氨及无机氮（ＴＩＮ） 呈显著的正相关，与亚硝酸盐（ＮＯ－２ － Ｎ） 和总有机碳（ＴＯＣ） 有比较明显的正相关；试验贝类死亡与弧菌浓度呈正相关，它们对弧菌的易感性依次为栉孔扇贝、虾夷扇贝、太平洋牡蛎、海湾扇贝、紫贻贝。

A study on organic pollution enhancing susceptibility of bivalve to vibrio

Organic pollution enhancing susceptibility of the bivalve to vibrio was studied by providing food and unexchanging water to cause organic pollution in the test ponds in the laboratory. The results indicate that the polluted period was longer, the vibrio quantity was higher; the vibrio density was extremely positively correlative to ammonia-N and TIN,quite positively correlative to NO 2 --N and TOC in the test ponds;the tested bivalve mortality was positively correlative to the vibrio density,and the susceptible order of the bivalve to vibrio was Chlamys farreri,Pecten yessoensis,Argopecten irradians, Crassostrea gigas and Mytilus edulis.
