On the eve of National Ecology Day, Tianjin Maritime Court organized police officers to visit and conduct research at Tianjin Port Coal Terminal Co., Ltd. Police officers conduct research on innovative technology, green production, and marine ecological protection by understanding the marine environmental issues arising from coal transportation, warehousing, and other production and operation activities of coal companies. 

Some police officers rushed to Caofeidian Central Fishing Port to conduct marine environment research. The police officers communicated with the person in charge of the fishing port on site, inspected the natural ecological environment around the fishing port, learned about the local marine environment, marine meteorology, and fishery resource knowledge from relevant personnel, and discussed feasible preventive measures regarding the danger of "rushing to the sea to pick up shells" and the management of fishing vessels during the fishing ban period and illegal fishing behavior.
