以瘤背石磺为研究对象，通过在不同盐度（5、15、25、35和45）环境下饲养，研究盐度对瘤背石磺消化系统的组织结构和超微结构的影响。试验显示：盐度能显著影响瘤背石磺幽门胃、贲门胃、肝胰腺以及肠道结构组织。随着盐度的升高，幽门胃和贲门胃细胞均出现不同程度的萎缩，而肝胰腺在低盐度时部分被溶解，出现“空泡化现象”，而高盐度时细胞损伤严重。另外，通过扫描电镜观察，高盐度对肠道绒毛细胞有破坏作用，随着盐度的升高，瘤背石磺前肠褶皱高度逐渐降低，至盐度35～45时表面逐渐呈现扁平化，消化吸收面积显著降低。试验结果表明，盐度对瘤背石磺消化系统组织结构有显著影响，盐度过高对消化系统组织损伤严重，消化吸收率显著降低。从组织学角度分析可见，盐度15左右是瘤背石磺适宜的养殖盐度。

Snail Onchidium struma was cultured at various salinities of 5 ,15 ,25 ,35 ,or 45 to evaluate the effects of salinity on histological structure and ultrastructure of the digestive system .The salinity was found to significantly affect the structure of pylorus ,cardia ,heptopancreas and intestine .The pyloric stomach and cardiac cells were shown to be to some extent contracted with the increase in salinity ,and some cells of the hepatopancreas were dissolved at low salinity ,and seriously damaged at high salinity , cavity being observed in the cells at a salinity of 35—45 under scanning electronic microscopy . T he intestinal villus height and digestive and absorptive area were found to be gradually reduced to flat at a salinity of 35—45 under a scanning electron microscope . T he histological analysis indicates that the appropriate culture of O .struma is conducted at a salinity of 15 .
