There’s a silent change taking place beneath the surface of many lakes in the United States. New generations of fish are growing smaller and weaker than their ancestors. Scientists claim this is a warning we can’t ignore. For the past several decades, fishermen and biologists noticed that the fish are getting smaller not only in number, but also in size. A newly published study revealed just how deep this change runs.
Researchers from the University of Michigan School for Environment and Sustainability ran a long-term study that included over a thousand lakes across the U.S. The research spanned over 75 years, and it paints a gruesome picture of an ecosystem under serious pressure due to changing freshwater levels as temperatures rise. But it’s not only the fish that are the main concern. The very balance of life in inland waters is in question. The shrinking of fish might seem like a small detail, but it carries big consequences for ecosystems, local communities, and the future of America’s lakes.
