Tech's Ripple Effect: Fish Migration Under Pressure
The Unseen River: How Technology Shapes Fish Migration Fish migration, an awe-inspiring journey across continents and oceans, is a cornerstone of aquatic ecosystems. These ancient wanderings ensure biodiversity, replenish populations, and connect freshwater and marine habitats. However, the relentless march of technology often leaves unseen scars on these delicate journeys. One of the most pervasive impacts comes from dam construction. Hydroelectric power, while renewable, fragments rivers and impedes fish passage. Traditional dams with low-flow spillways simply don't provide adequate water volume for many species to navigate upstream. While modern designs incorporate fish ladders and bypass systems, these aren't foolproof and can be costly to implement.
