Pimephales promelas (Fathead Minnow), Larval Survival and Growth Test, (EPA Method # 1000.0)


Biomonitoring provides an effective means by which the toxicity of discharges from municipal, industrial, and mining operations can be tested. Among the advantages of biomonitoring is the ability to test complex effluents containing a broad range of contaminants.


Biomonitoring, when used in conjunction with chemical analyses, can generate data capable of identifying a much wider range of contaminants


The chronic test measures significant differences in lethality and in reproduction (Ceriodaphnia dubia) or growth (fathead minnow – Pimephales promelas) between control and effluent-exposed organisms.
