Gene response profiles for Daphnia pulex exposed to the environmental stressor cadmium reveals novel crustacean metallothioneins. Daphnia pulex is the most common species of the water flea, an organism which can be found in almost every permanent, eutrophic (nutrient-rich) water body. A few species are marine, but generally Daphnia , including Daphnia pulex , are freshwater organisms. But Daphnia are declining in Lake Superior and nearly every other body of water in the Great Lakes region.Their numbers have been decimated by a fierce invasive predator, the spiny water flea Culture water should be 18-20°C for daphnia and 24-31°C for moina. Position the light over the vessels and set on a 12- to 20-hour photoperiod. Maintain a pH of 6.5 to 9.5.

Watch its legs swirl food to its mouth. Its tiny size and transparent body helps it hide from hungry insects and fish. The water flea (Daphnia magna) was used as a sensitive indicator for assessing the toxicity due to synthetic detergents. Acute and chronic toxicity of detergents to the water flea was studied under laboratory conditions by following the median tolerance limit (TLM) at 48 hr and the rate of survival. … 2010-12-31 2017-08-16 The sub-lethal and reproductive effects of acute and chronic exposure to flowback and produced water from hydraulic fracturing on the water flea Daphnia magna Article Jan 2017 It’s baby making time!
