Shipping plays a very important role in the movement of most goods in the world. Ships are a means of transport used to transport goods at sea. Every day, there are many ships moving back and forth between different seas at a high frequency. Each ship’s voyage can be full, low-load, or no-load. Using ballast water is a long-standing solution used to balance and stabilize ships during voyages. Ballast water is taken into the ship and discharged anywhere in the sea. This means that the organisms in the ballast water can also migrate to any part of the sea. There are beneficial organisms and harmful organisms for the ecosystem in the waters they are brought in. Organisms that grow unprofitably will destroy the stable ecology of the seas they reach. To solve this problem, it is necessary to have appropriate legal policies and solutions to treat ballast water. This short review presents current regulatory policies and solutions for ballast water treatment. Some challenges and prospects for future regulatory policies and solutions for ballast water treatment are also outlined.
