A study of the effect of lime‐neutralized iron hydroxide suspensions on eggs and alevins of brook trout (Salvelinus fontinalis) and coho salmon (Oncorhynchus kisutch) was conducted with a modified proportional diluter. Effects were interpreted from data on hatchability, survival, and growth in five test concentrations and control. Growth of 90‐day‐old coho salmon alevins was reduced in water containing 1.27 mg Fe/liter of lime‐neutralized suspended iron, whereas hatchability was unaffected in the highest concentration tested, 10.5 mg Fe/liter, However, 10.5 mg Fe/liter water had no measurable effect on hatchability, survival, and growth of brook trout alevins. The safe upper limit of lime‐neutralized suspended iron for hatchability, survival, and growth of coho salmon alevins may lie between 0.97 and 1.27 mg Fe/liter.
