Abstract

The recent spread of dreissenid mussels to various bodies of water in the western US has sparked interest by many state and federal agencies to develop protocols to stop further expansion. Quagga mussels (Dreissena rostriformis bugensis) are of particular importance as they are currently the most widespread dreissenid species in the region. This project examined the susceptibility of quagga mussels to hot-water sprays at different temperatures and durations of spray contact at Lake Mead (Nevada-Arizona, USA). Emersed adult quagga mussels were exposed to hot-water sprays at 20, 40, 50, 54, 60, 70, and 80°C for 1, 2, 5, 10, 20, 40, 80, and 160 s. Sprays at ≥60°C for 5 s were shown to be 100% lethal. Sprays of 54°C for 10 s, 50°C for 20 s, and 40°C for 40 s also resulted in 100% mortality. A spray temperature of 60°C for 5 s is recommended for mitigating fouling by quagga mussels.

摘要

最近，淡水贻贝已传播到美国西部的多个水体，这引起了许多州和联邦机构的兴趣，他们希望制定协议来阻止其进一步扩散。斑马贻贝（Dreissena rostriformis bugensis）尤为重要，因为它们是该地区目前分布最广泛的淡水贻贝物种。本项目研究了在米德湖（内华达州-亚利桑那州，美国），不同温度和喷雾接触时间下，热水喷雾对斑马贻贝的敏感性。将成年斑马贻贝暴露在 20、40、50、54、60、70 和 80°C 的热水喷雾中，时间分别为 1、2、5、10、20、40、80 和 160 秒。结果表明，温度≥60°C 且持续 5 秒的喷雾可达到 100%的致死率。54°C 持续 10 秒、50°C 持续 20 秒和 40°C 持续 40 秒的喷雾也会导致 100%的死亡率。因此，建议采用 60°C 持续 5 秒的喷雾温度来减轻斑马贻贝的污损。
