Daphnia physiology
WebAbstract. The freshwater crustacean Daphnia is well known for its phenotypic plasticity, in which environmental cues are perceived by the nervous system and … WebDaphnia cultures should not be harvested until they reach a minimum average density of 10 daphnia per 20 ml. Daphnia should not be harvested at a rate that decreases their numbers below 10 daphnia per 20 ml. In other words, do not harvest more than what would decrease the total average numbers below 10 daphnia per 20 ml.

WebDaphnia suppressed small algae, while larger species compensated in terms of biomass for the losses. Autotrophic picoplankton declined with zooplankton density in both gradients. Gelatinous, colonial algae were fostered by both zooplankton functional groups, while medium-sized (ca. 3,000 microm3), non-gelatinous algae were suppressed by both. WebDaphnia magna (common name "water fleas") are tiny freshwater crustaceans. They are filter feeders, and can survive in culture by eating algae, bacteria, or yeast. The body diameter of adult females is about 3–5 mm (Clare, 2002).
