Fish Tumors and other Deformities (BUI #4)
In order to remove the impairment, the following removal criteria must be met:
- Incidence rates of fish tumors or other deformities do not exceed rates at unimpacted control sites; AND
- Survey data confirm the absence of neoplastic or preneoplastic liver tumors in bullheads or suckers as compared to control sites; AND
- No reproductive deformities in observed resident species as compared to control sites.
This BUI is also designated as impaired by the SLR AOC at Cornwall/Akwesasne.
