Marine bioinvasion refers to the introduction of non-native species into marine ecosystems, often disrupting local biodiversity and affecting ecosystem stability. These invasive species, such as zebra mussels and lionfish, can outcompete native species for resources, alter food webs, and threaten endemic populations. Bioinvasions are frequently facilitated by human activities like shipping, aquaculture, and coastal development. Addressing bioinvasions requires coordinated international efforts, such as regulations on ballast water discharge, habitat restoration, and species monitoring. Effective management of marine bioinvasion is vital for safeguarding biodiversity, ecosystem health, and the livelihoods dependent on native marine species.
