open access: yesJournal of Applied Ichthyology, Volume 2024, Issue 1, 2024.
Caohai Lake, hailed as a gem on the Yunnan–Guizhou Plateau, is currently being faced with serious biological invasion threats. Among the most influential invasive species, the Procambarus clarkii (Girard, 1852) is causing various adverse effects on the lake’s ecosystem. However, there has been little attention paid to this issue for a long time.
