Since P. merguiensis , P. indicus and other wandering type of penaeid shrimps from dense schools, fishermen can easily collect large number of spawners during peak seasons.
2. Posterior part of trunk is terminated by a pair of caudal styles. 3. Body is entirely enclosed in a bivalved It follows the nauplius stage and precedes the post-larva. Zoea larvae swim with their thoracic appendages, as opposed to nauplii, which use cephalic appendages, and megalopa, which use abdominal appendages for swimming. Artemia sp.

Subclass iii. Ostracoda: 1. Indistinctly segmented body bearing usually up to two pairs of non-foliaceous trunk appendages.
The nauplius larva of crustaceans has three pairs of cephalic limbs, all of which aid in swimming while the second two are further involved in feeding. Cirripede and rhizocephalan nauplii differ from those of other crustaceans, including the Ascothoracida, in having conspicuous horns on either side near the front on the head.
It relies on stored yolk as an energy source. Depending on temperature, it swims weakly for about 12 -20 hrs and then molts into the metanauplius larva (= second instar).
The first larval stage for crabs, lobsters, shrimp, barnacles, copepods, and some other crustaceans is called a nauplius. The nauplii of different species all look alike so they are hard to tell apart. These larvae live in the water column as part of the zooplankton. They’re stealthy little creatures in that they blend in with many zooplankton.
Estuaries are now dominated by the immigrant Australasian species Elminius modestus Darwin, 1854, which is accompanied at low-tide levels by Balanus crenatus Bruguière, 1789, and B. improvisus Darwin, 1854; all three can occur sublittorally.
