在北方半球的34种名义上的七鳃鳗物种中，有10种濒临灭绝; 9种至少在部分范围内是脆弱的，还有一种已经灭绝。主要原因是由于污染和河流调节造成的生境退化。四个优先保护的建议：1。保护所有被列为濒危的七鳃鳗物种或种群; 2.在必要时，恢复非寄生物种的产卵溪流，并清除或绕过任何阻碍进入产卵地点的障碍; 3.保护溯河产卵物种的永久性淡水居民种群，特别是Entosphenus tridentatus，Lampetra ayresi，L. fluviatilis、日本裸腹鱼（Lethenteronjaponicum）和海岩吸鳅（Petromyzonmarinus）：4.亚洲七鳃鳗保护现状的研究。
Among the 34 nominal lamprey species in the Northern Hemisphere, ten are endangered; nine are vulnerable at least in part of their range, and one is extinct. The major cause is habitat degradation through pollution and stream regulation. Four conservation priorities are recommended: 1. The protection of all lamprey species or populations thereof listed as endangered; 2. where needed, the rehabilitation of the spawning streams of non-parasitic species and the removal or circumvention of any barriers preventing access to the spawning sites; 3. the protection of permanent freshwater resident populations of anadromous species, specifically of Entosphenus tridentatus, Lampetra ayresi, L. fluviatilis, Lethenteron japonicum and Petromyzon marinus: 4. the study of the conservation status of Asian lampreys.
