Description:
Oysters sampled in February 1992, from a low salinity site (3 ppt) in Apalachicola Bay, Florida, showed digestive tubule atrophy when salinity site (18 ppt) 16 kilometers away. xperiments designed to induce tubule atrophy in the and two salinity stress tests. o quantify tubule condition for each oyster, inside to outside diameter tubules per animal using an ocular micrometer. igher tubule ratios indicated greater tubule atrophy. he experiments showed poor nutrition, perhaps due to low salinity, may have played a significant role in the tubule atrophy of Apalachicola Bay oysters.
