- Abstract
This article discusses changes in multigenerations of freshwater fishes in Australia following acute exposure to nominal levels of endocrine disrupting chemicals including nonylphenol and endosulfan. The authors exposed crimson-spotted rainbowfish (Melanotaenia fluviatilis) prior to spawning for a short period to these toxicants and observed changes over two generations in offspring and reproductive ability. They found fertility and hatch rates were reduced following exposure in the adult fish. They observed major reproductive effects in hatchability of the first generation offspring and in the male gonadosomatic. They concluded that the reductions in hatchability have the potential to significantly impact exposed rainbowfish populations due to reduced larval production.
