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. Keep ammonia concentrations below 0.2 mg/L.

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.

Some types of Daphnia can be seen Non-steroid anti-inflammatory drugs (NSAIDs) have been frequently detected in aquatic ecosystem and posed a huge risk to non-target organisms. The aim of this study was to evaluate the toxic effects of three typical NSAIDs, diclofenac (DFC), acetaminophen (APAP) and ibuprofen (IBP), toward the water flea Daphnia magna. Dec 5, 2019 Daphnia pulex is a species of planktonic crustacean of freshwater ecosystems occurring in different kinds of bodies of fresh water.
