Legal basis: Article 4 of the Regulations on Traffic Safety Management of Fishing Port Waters in People's Republic of China (PRC) refers to ships engaged in fishery production and ships belonging to the fishery system that serve fishery production, including fishing boats, breeding boats, aquatic product distribution ships, refrigerated processing ships, oil tankers, supply ships, fishery guidance ships, scientific research ships, teaching practice ships, fishing port engineering ships, tugboats, traffic ships, barges, fishery administration ships and fishing boats. It does not include ships engaged in carrying tourists for fishing activities in recreational fisheries. The state and relevant departments of our province have not formulated relevant laws and regulations to manage such ships, and there is no unified construction standard and inspection specification for such ships, which has great security risks.
