In Pimephales promelas (fathead minnow), an LC 50 of 13 400 μg l −1 over 96 h was measured in freshwater, 24.1 °C, pH 7.7, and dissolved oxygen 6.8 mg l −1 . 2011-02-03 · The water flea's genome is described in a Science paper published this week by members of the Daphnia Genomics Consortium, an international network of scientists led by the Center for Genomics and Bioinformatics (CGB) at Indiana University (IU) Bloomington and the U.S. Department of Energy's Joint Genome Institute.
