The free-swimming first stage of the larva of certain crustaceans, having an unsegmented body with three pairs of appendages and a single median eye.

[New Latin, from Nauplius, former genus of crustacean (later discovered to be a larval stage of other genera), from Latin nauplius, paper nautilus, from Greek nauplios, nautilus (probably the pearly nautilus of the Indian Ocean) : naus, nau-, ship; see nāu- in the Appendix of Indo-European roots + plein, to sail, float, swim (the animal being so called because it was thought to sail in its shell like a ship and use its arms as oars); see pleu- in the Appendix of Indo-European roots.]

Nevertheless, a primary feeding schedule has been established based mostly on live prey (rotifers and Artemia nauplii) and early weaning during the third or fourth week of development, which is shown in Figure 1.
Recently hatched brine shrimp (Anemia sp.) nauplii were also provided (at a density of about 6 nauplii m[L.sup.-1]) from the third zoeal stage (ZIII) onward until larvae reached the megalopal stage.
Tenders are invited for Empanelment of individuals suppliers, registered firms, shrimp hatcheries for the supply of shrimp nauplii, p.monodon and p.indicus to adak hatchery at odayam, varkala
After incubation for 24h, nauplii were collected with a pasteur pipette and kept for an additional 24h under the same conditions to reach the metanauplii (mature larvae) stage.
Exceptional cases are exemplified by members of the Monstrillidae and Thaumatopsyllidae, both of which are protelean parasites, with infective nauplii and non-feeding planktonic adults.
Following 48 h of hatching, nauplii were collected (n = 10 nauplii/sample/concentration) and added in tubes, each one with 0.5 mL of the sample (62.5 mg x [mL.sup.-1], 125 mg x [mL.sup.-1], or 250 mg x [mL.sup.-1]) plus 4.5 mL of artificial marine water.
In spring, the most frequent (>70% of all collected samples) zooplankton taxa were Keratella cochlearis, Keratella quadrata, Polyarthra dolichoptera, Chydorus sphaericus, and copepodites and nauplii of cyclopoid copepods (Table 1).
was followed by collection of Sea water from Kuramo beach (Atlantic Ocean) in Lagos before been sieved and allotted into hatching chamber(plastic soap dish) which was used to hatch shrimp egg and allowed to mature as nauplii in 48-72 hr.
