Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

In the 1959 U.S. Fish and Wildlife Service publication entitled “Lethal Doses of Several Commercial Chemicals for Fingerling Channel Catfish” (U.S. FWS, 1959), the toxicity of numerous chemicals used in the channel catfish culture were reported. The LD50 for channel catfish fingerlings was determined to be 624 mg/L and an LD0 or a No Observed Effects Concentration (NOEC) was determined to be 489 mg/L.

The test conditions used to perform the tests were the same as those described in the supporting study entitled “The Chemical Control of Some Diseases and Parasites of Channel Catfish" (Clemens and Sneed, 1958). The bio-assay methodology used to determine the toxicity of the test material to channel catfish fingerlings was reported in the supporting study entitled “Bio-Assay Methods for the Evaluation of Acute Toxicity of Industrial Wastes to Fish” (Duodoroff et al., 1951).
