JINAN, Nov. 13 (Xinhua) -- As a province noted for its major marine fishery economy, Shandong has been actively building marine farms in recent years, aiming to continuously enrich the "blue food depot."

To date, Shandong has built 139 "marine farms" at or above the provincial level, including 71 at the national level, or 38 percent of the country's total at the level. The province now boasts an integrated industrial chain for marine fishery that ranges from aquaculture, fishing to intensive processing.

The output of marine aquatic products in Shandong reached 8.25 million tonnes with an added value exceeding 100 billion yuan (about 14.09 billion U.S. dollars) in 2024, topping among all regions at the provincial level in the country.
