In the past 10 years, 2,133 Chinese illegal fishing vessels have been seized in the excusive economic zone(EEZ) of Korea, 131 billion won of the amount of a bond the security fulfillments of law enforcement has been imposed by the prosecutor with a judicial police officer’s request. Based on the Article 73 of the United Nations Convention on the Law of the Sea, “The coastal Bureau shall take enforcement measures such as boarding, searching, dispatching, and judicial procedures to ensure the implementation of its laws, and immediately release seized ships and crew members to the ship’s property.”, the amount of a bond is imposed on violators (including shipowners) for the property of ships and the human rights of seafarers until the trial is finalized and released if they are paid to related agencies although it is not stipulated in the Criminal Procedure Act, Accordingly, neighboring countries such as Korea, Japan, and China operate similar systems on the procedure for imposing and paying bond for foreign illegal fishing vessels in the exclusive economic zone (EEZ) under the United Nations Convention on the Law of the Sea. This paper studies and examines the current status and nature of bond imposed on illegal foreign fishing vessels and compares the bond system with neighboring countries as well as Korea, so that problems which is derived by current system abd proposed improvement plan. In particular, through a comparative study of procedures for imposing bond on violating ships in neighboring countries such as Japan and China, it was intended to compensate for the deficiencies of the bond system in Korea. First, the neighboring countries such as Japan and China are investigating independently in the process of cracking down on violations of foreign ships (stop a ship, boarding, searching, and captured) at sea, but in case of Korea, Korean coast guard officials can take action and investigation under the direction by prosecutors. The Criminal Procedure Act, which was revised from 2021, has given judicial police officers the right to terminate the investigation and also has been converted to a cooperative relationship with prosecutors, but is still under the direction of prosecutors. Therefore, by applying the revised Criminal Procedure Act, regulations of the prosecutor’s direction for the judicial police officer under the direction of the prosecutor under act on the exercise of sovereign rights on foreigners’ fishing should delete. Second, it is desirable to amend the Act on the exercise of sovereign rights on foreigners’ fishing. Because the authority to impose and notify bond give the judicial police officers belonging to the Korea Coast Guard, as in the case of Japan and China, which determine the amount of bond imposed on violating ships and notify violators. Third, there are cases where brokers who pay the bond on behalf of the violators and collect fees are arrested because the current law does not stipulate the payment subject of the bond and the deadline, so the payment subject of the bond is limited to the violators, captains, and ship owners. In addition, it is necessary to increase transparency in the payment process of bond by designating the payment deadline as 10 days. Lastly, as the standard for imposing bond has been raised significantly, more and more shipowners or persons in charge of the illegal fishiing vessels are unable to pay bond, so efforts by related agencies and diplomatic cooperation with the Chinese government are urgently needed to ensure that 100% of the bond is paid. In addition, it is desirable to establish a "protection fund" to support projects such as compensation for damage to fishermen and to grant the Commissioner of the Korea Coast Guard a management entity as collateral imposed by illegal fishing is attributed to the national treasury.
