Two 9‐month continuous‐flow bioassays and several intermediate length continuous‐flow tests were conducted to determine safe levels of Aroclor 1242, 1248, and 1254 for the fathead minnow (Pimephales promelas) and Aroclor 1248 for the flagfish, Jordanella floridae. Calculated 96‐hr LC50 values for newly hatched fathead minnows were 7.7 μg/liter for Aroclor 1254 and 15 μg/liter for 1242. Three‐month‐old fatheads had a 96‐hr LC50 of 300 μg/liter for 1242. Reproduction occurred at and below 1.8 μg/liter 1254 and at and below 5.4 μg/liter 1242. Newly hatched young were the most sensitive life stage. Growth of young fatheads was also affected above 2.2 μg/liter 1248, and none survived above 5.1 μg/liter after 30 days. Young flagfish did not survive at 1248 concentrations above 5.1 μg/liter and did not grow well above 2.2 μg/liter. Tissue residues in fathead minnows ranged from 0.7 μ/g 1248 in control fish to 1036 μ/g 1254 in fish held for 8 months in water containing 4.6 μg/liter 1254.
