KWRRI Research Reports
Fish and amphibian eggs, embryos and early posthatched (larval) stages were evaluated as bioindicator organisms with which to monitor the quality of natural water resources. Eggs of 9 species were cultured in water collected from each of 11 Inner Bluegrass rivers and streams. The latter were chosen to represent water sources varying in quality from extremely poor to good. Selection was based on the sources and magnitude of pollution, and the diversity and density of piscine populations. Cultures were maintained in vitro, using 12-hour changes of water.
Averaging data for all 9 animal species, egg hatchability (embryonic survival) ranged …
