Why is fishing not allowed in a sanctuary?

Fishing is typically not allowed in a sanctuary to protect vulnerable marine ecosystems and the species that inhabit them. Sanctuaries are designated to conserve biodiversity, promote the recovery of overfished populations, and maintain ecological balance. By prohibiting fishing, these areas can serve as safe havens for marine life, allowing for research, education, and the regeneration of habitats. This helps ensure the long-term health of the ocean environment.
