3. Ailun Bay Marine Ranch

Ailun Bay Marine Ranch is one of China's first batch of national marine ranch demonstration zones. It supports large-scale ecological aquaculture of kelp, abalone, sea cucumbers, and other premium seafood across a 68,000-mu (about 4,533-hectare) integrated marine ranch ecological complex.

At Ailun Bay, visitors can enjoy a "sea–land" experience: floating platforms and large fishing cages offer a taste of life as a sea herdsman, while on land, exhibition halls and science centers combine learning with fun.
