What is the defining duality regarding the modern perception of the lamprey in North America?

Answer

Potential food source versus ecological menace

The most defining feature of the lamprey's modern perception is its dual role. On one hand, it remains an essential part of the diet for specific local communities with cultural ties, representing a traditional food source. On the other hand, particularly in the Great Lakes region, the sea lamprey is viewed as an ecological menace that causes massive economic damage to valuable species like salmon and lake trout, leading governmental bodies to implement widespread management and control strategies against it.
