摘要在水槽流中，研究了水流速度和壳体取向对紫贻贝附着性的影响。流速对附着线的数量和附着力有显著影响。相对于贻贝的取向，没有观察到附着在贻贝身上的丝线数量的影响，但在高流量实验结束时，贻贝的取向显著地受到位置：腹上流的影响。通过测量已建立的附着线的数量和单个分离的附着线的附着强度来估计附着体的潜在强度。在静水中，测量的附着强度占估计的附着潜在强度的21%，但在19.4厘米秒-1的水流中，测量的附着强度占81%。这一观察结果表明，建立的线程数量与力之间的关系。
Abstract The effects of flow velocity and shell orientation in a flow field on byssus thread attachment were investigated in the blue mussel Mytilus edulis L. in a flume flow. The number of established byssus threads and the strength of byssus attachment were significantly affected by flow velocity. No effect on number of attached byssus threads was observed relative to orientation of the mussel, but mussel orientation at termination of the high flow experiments was significantly dominated by the position: ventral upcurrent. By measuring the number of established byssus threads and the strength of attachment of individual detached byssus threads the potential strength of attachment was estimated. In still water the measured strength of attachment constituted 21% of the estimated potential strength of attachment, but in a 19.4 cm sec-1 flow the measured strength of attachment constituted 81%. This observation indicates, that the correlation between the number of etablished byssus threads and the force of a...
