It is well known that mammalian embryos have periods of particular sensitivity known as critical periods when their susceptibility to foreign compounds is maximal. In the case of fish, data from an extensive series of life cycle toxicity tests have indicated that the embryo-larval and early juvenile stages are generally more susceptible to toxicants than later stages. However, since most work on fish eggs has involved continuous exposure to the pollutant until hatching either from fertilization or from the eyed stage, it has not been possible to record accurately the actual stages of development at which the egg is most sensitive. In an attempt to overcome this problem and to detect any critical periods, the toxicity of three common heavy metal pollutants was examined at six different embryonic and two alevin stages of development.
