rotundiformis; the brine shrimp Artemia at several life stages (i.e., nauplii, juveniles and adults); copepods Pseudodiaptomus euryhalinus at several life stages (nauplii, copepodites and adults); wild zooplankton; and even yolk sac larvae from the same species.
After the nauplii metamorphized to mysis stage, water samples (1 L) were collected from the upper, center and bottom of the barrels.
nauplii (at a density of about 2 nauplii m[L.sup.-1]) according to the different periods of addition (PNR experiment) or withdrawal (PRS experiment) of food (see Fig.
LC50 values of ethanol and water extracts were determined by a plot of percentage of the shrimp nauplii killed against the concentrations of extracts.
Lecithotrophic nauplii are common to most truly parasitic taxa belonging to the orders Cyclopoida (including "Poecilostomatoida") and Siphonostomatoida (Paterson 1958; Carton 1968; Izawa 1986, 1987; Raibaut 1996; Boxshall 2005; Ivanenko et al.
Predation by cyclopoid copepods may be strong (Brandl, 2005); however, in spring, when among copepods there are numerous non-predatory nauplii and copepodites, their impact on rotifers cannot be essential in Lake Vortsjarv.
At this stage, nauplii larvae are still nourished by yolk sacs and we supplied no further food during the experimental period.
To the test execution, the Brine shrimp nauplii were incubated in artificial sea water in room temperature, in a 24 hour period.
Brine shrimp nauplii were obtained by hatching brine shrimp eggs in simulated sea water prepared by dissolving 38 gm fresh salt in 1 L distilled water.
Copepod eggs made up 76% of the diet of larval Atlantic silverside in Pettaquamscutt River, whereas copepod nauplii made up 73% of their diet in Point Judith Pond.
After 48 hrs, encysted eggs of the brine shrimp (20 nauplii) were added to each set of the vials containing ethyl acetate crude extract dissolved in 5% DMSO and filled to 10 mL total volume with artificial salt water.
