Wow. Researchers say that worldwide accounting of freshwater fish harvested for consumption is “inaccurate and grossly underestimated” and that the amount “could equal the current amount of marine fish caught.”
As a consequence of this, planning for dams and other river projects doesn’t adequately account for the effect they might have on fish populations.
That’s bad news not only for commercial harvest of freshwater fish, but recreational angling as well.
“It’s not a question of whether we should stop using water for other purposes, but we need to consider what harms are being created, and if they can be mitigated,” said one of the Michigan state scientists. “People are losing jobs and important sources of food because fish habitats are being degraded, greatly reducing fish production in these waters.”
