(invertebrate zoology)
A larval stage characteristic of many groups of Crustacea; the oval, unsegmented body has three pairs of appendages: uniramous antennules, biramous antennae, and mandibles.



the plankton larva of numerous species of the family Crustacea. The body is unsegmented and has three pairs of appendages. In front of the mouth there are uniramous sensory antennules; in back there are biramous antennae and mandibles for swimming. The nauplius has a median eye. Between the mandibles and the anal opening there is a growth zone, where, as development progresses, the postnauplial segments with appendages develop.

5%, used as a vehicle control, caused very little mortality among Artemia salina nauplii larvae (Fig.
Samples of newly hatched Artemia nauplii, enriched Artemia and postlarvae were washed with distilled water and frozen (-20[degrees]C) until analysis.
Acute exposure test for Artemia nauplii was carried out according to the OECD 202 test guide.
Although copepod nauplii can serve as an important resource for larval fish less than eight mm TL (Bremigan et al.
In addition, it is unlikely that food availability or food quality altered results, as crabs in all treatments were fed identical diets of fresh and enriched Artemia nauplii and were fed in excess to ensure that food availability did not limit growth.
About 10 to 15 nauplii were added to each solution containing the samples, negative control, and positive control.
Melibe feeds differently than most other gastropods because it lacks a radula and uses a large, tentacle-lined oral hood to capture zooplankton, nauplii, and other small organisms floating by in the water column (Hurst, 1968; Watson and Trimarchi, 1992).
The major groups of zooplankton were copepods rotifers sergestidae lucifer gastropod larvae bivalve larvae pelagic polychaetes nematodes crustacean nauplii insects and mysidacea.
Abstract Larval snakehead Channa striatus were fed with three cladocerans (Ceriodaphnia cornuta, Moina micrura and Daphnia carinata) and Artemia nauplii at the rate (500 Ind.
After 24 hours, the tubes were inspected using a magnifying glass and the number of survived nauplii in each vial was counted and observations were recorded for each vial.
Five different types of zooplankton were counted: Rotifer, Cyclopoid, Calanoid, Nauplii and Cladocera.
