저질에 따른 꼬막(Tegillarca granosa)의 염분내성 = Salinity Tolerance of the Bloody Clam, Tegillarca granosa for Sedimentary Composition

다국어 초록 (Multilingual Abstract)

The present study was conducted to know the salinity tolerance of the bloody clam, Tegillarca granosa (Linnaeus) caught in Gang-jin Bay from May to June in 2000.
In the experimental groups of sandy-mud, the survival and infiltration rate were not bad at 20~40ppt, but all the bloody clam, Tegillarca granosa died at more than 50ppt and less than 10ppt before the experiment finish.
In the experimental groups of muddy, the survival and infiltration rate wrer not bad at 20~35ppt and then 40ppt, 45ppt. All the bloody clam, Tegillarca granosa died at more than 50ppt and less than 10ppt.
The infiltration rate was high at 25~35ppt in the both of two experimental groups. In the sandy-mud, the bloody clam, Tegillarca granosa infiltrated less than half of their shells at 25ppt, 30ppt but in the muddy, they infiltrated more than half of their shells at 25ppt, 30ppt, 35ppt.
