fish

The US Army Corps of Engineers builds a 700-foot-long fish passage at the City of Buffalo’s Freedom Park on Unity Island to support Emerald Shiner fish.

Tumors and deformities were historically elevated in fish populations in the Black River and Cuyahoga River Areas of Concern (AOCs) as a result of legacy industrial pollution and poor water quality. Contaminant source control and water quality improvements in both AOCs, and remediation work in the Black River AOC, reduced rates of fish tumors and deformities to meet Ohio’s AOC restoration targets, prompting the removal of the Fish Tumors and Other Deformities Beneficial Use Impairment (BUI) from these AOCs.
