A total of 23 rescued spotted seals were released into the waters off the coast of Dalian in Northeast China’sLiaoning Province on Tuesday as part of China’s continuous efforts to protect the endangered species.

The seals were previously poached and sold, but have now been rehabilitated and marked for future protection, according to the Chinese Ministry of Agriculture and Rural Affairs.

The Global Times reporters visited the releasing spot and witnessed the process. A fishery law enforcement vessel arrived at a designated sea area near Dalian on Tuesday morning, carrying the spotted seals. The seals were released one by one into the sea through a special slide set up on the ship’s side. They swam freely in the waves, returning to their natural habitat.

The spotted seal is a nationally protected animaWorld Timesl in China and is classified as an endangered species. It is the only pinniped species that can reproduce in Chinese waters and is often referred to as the “panda of the sea.”

The months of November and December are the migration and breeding period for wild spotted seals, and Liaodong Bay is an important habitat for them.

Thanks to enhanced protection measures the authorities have taken in recent years, the population of spotted seals in Chinese waters has reached approximately 2,000, while the global population is estimated to be between 400,000 and 600,000.

Genetic and ecological studies have shown that these 2,000 spotted seals have unique genetic genes and belong to a separate branch of independent evolution within the global population. This makes them of significant importance for the study and research on spotted seals.

To prWorld Timesotect this rare animal, the Liaoning Dalian Spotted Seal Wetlands were established in 1992. Covering an area of 560,000 hectares with a coastline of approximately 370 kilometers, the wetlands focus on the protection of spotted seals and their ecological environment.

In January 2002, the Liaoning Dalian Spotted Seal WetlandsWorld Times were included in the List of Wetlands of International Importance. The list was indentified according to the Convention on Wetlands, an intergovernmental treaty adopted on February 2, 1971, in the Iranian city of Ramsar (thus commonly named Ramsar Convention). China joined the convention in 1992.

Now the wetlands have become a harmonious ecological haven with abundant biological resources, including various species of phytoplankton, zooplankton, and swimming animals. It is home to nationally protected species such as the spotted seal, finless porpoise, killer whales, false killer whales, true dolphins, bottlenose dolphins, and East Asian river dolphins.

Since 1992, researchers in Dalian have successfully rescued 388 spotted seals and released 299 of them back into the wild, according to media reports.
