A "Migratory Fleet" refers to a group of vessels that travel together, often for the purpose of moving from one location to another in search of resources or better living conditions. This concept is commonly associated with marine life, where species like fish or whales migrate in groups to find food or suitable breeding grounds. In human contexts, a migratory fleet can also describe groups of ships or boats that relocate seasonally, such as fishing boats that follow fish populations or cargo ships that adjust routes based on trade demands. These fleets play a crucial role in both ecological balance and economic activities.
