1. Translocation is used to conserve mussels, yet there remains a debate about its merit owing to poor understating of its effects on transported mussels.
2. This study evaluated survivorship, body condition, and total glycogen and lipids for one common and widely distributed species (Cyclonaias pustulosa), two rare species (Cyclonaias petrina; Lampsilis bracteata), and one species complex (Fusconaia sp. – Fusconaia chunii and Fusconaia flava) from the East Fork of the Trinity River and the Llano River of Texas.
3. Survivorship estimates for C. pustulosa and Fusconaia sp. using the Kaplan–Meier estimator were high in the East Fork. Body condition, glycogen, and total lipids varied for C. pustulosa and Fusconaia sp., which may have indicated a short‐term impact. For the Llano, survivorship of C. petrina and L. bracteata was high for the resident treatments but significantly reduced for the translocation treatments.
4. The decline in survivorship for C. petrina was mirrored by decreases in the body condition, which may indicate inability to acclimate to novel environments. For L. bracteata, declines in survivorship were due to predation by Procyon lotor, racoon. A large flood of 3,766 m³ s⁻¹ at the end of the study eliminated both study sites.
5. The findings of this study show that translocating mussels can be successful; however, sublethal effects and mortality may still occur. These effects are rooted in species‐specific differences, which is not unexpected because mussel species vary in how they cope with environmental change based on their life‐history traits. However, these traits are rarely considered when translocating mussels.
6. To complicate matters, most mussel species have yet to be evaluated on how they respond to translocation, and for species where such information is available, adults are the primary focus. Addressing these knowledge gaps is critical for determining the appropriateness of translocation and improving its efficacy.

关于贻贝易位及其保护意义的警示性故事：来自德克萨斯州中部两个流域的案例研究

1. 易位是用来保存贻贝的，但是由于其对运输贻贝的影响被低估了，因此关于贻贝的优点仍存在争议。
2. 这项研究评估了生存，身体状况，以及总糖原和一个共同的脂质和广布种（Cyclonaias脓疱），两个稀有物种（Cyclonaias petrina ;美丽蚌属苞），和一个物种复杂（Fusconaia。SP - Fusconaia chunii和Fusconaia黄花），来自三位一体河的东叉和得克萨斯州的拉诺河。
3. C. pustulosa和Fusconaia sp。的存活估计。在东叉地区，使用Kaplan-Meier估计器的比例很高。身体状况，糖原和总脂质改变为C.脓疱和Fusconaia属，这可能指示的短期影响。对于Llano的，生存的C. petrina和L.苞较高驻地治疗但易位治疗显著减少。
4. 梭状芽胞杆菌存活率的下降反映在身体状况的下降上，这可能表明无法适应新的环境。对于Bracteata L.，存活率下降的原因是浣熊的Procyon lotor捕食。在研究结束时，发生了3,766 m ³ s ^-1的大洪水，这两个研究地点均被淘汰。
5. 这项研究的结果表明，贻贝易位是成功的。但是，亚致死作用和死亡率仍然可能发生。这些影响源于特定物种的差异，这并不意外，因为贻贝物种根据其生命历史特征应对环境变化的方式各不相同。但是，在转移贻贝时很少考虑这些特征。
6. 使事情复杂化的是，大多数贻贝物种尚未评估其对易位的反应，对于可获得此类信息的物种，成虫是主要重点。解决这些知识空白对于确定易位性和提高其效率至关重要。
