After the shrimp underwent metamorphosis from zoea stage to mysis stage larvae, there were no significant differences between the experimental and control groups in the metamorphosis rate, consistent with previous research (Yang et al., 2011).
Once hatched, only the actively swimming zoea larvae (displaying a positive phototropism) produced by the different females were collected and mixed in a 500-mL glass beaker, to avoid possible influence of genetic differences and/or parental conditions (e.g., age, health, physiological and nutritional state, diseases) on the performance of larvae and juveniles in the experiments.
Mating occurs mostly in oligohaline and mesohaline regions of estuaries, and is followed by migration of females to the lower estuary and the adjacent coastal ocean, where eggs are brooded externally before hatching as planktonic zoea larvae.
For the family Porcellanidae it is recognized that the larval development cycle is composed by one prezoea, two zoea (I and II), and one megalopa stage (Wehrtmann et al., 1996; Mujica & Pereira, 2009), however, there are still species of this family without a complete larval description.
The three collaborators also underwent practical sessions on natural food culture, broodstock management, larval rearing from zoea to megalopae, nursery rearing, and other activities involved in the hatchery, nursery, and grow-out operations.
The seedlings used for culture are the post larval stage (moulted from zoea) and procured from a commercial shrimp hatchery and stocked in the ponds at a density of 2300-3000 larvae/ha.
australis were calanoid copepods, Munida gregaria zoea larvae, Euphausia lucens caliptopis, furcilia, juveniles and adults as well as several ichthyoplankton organisms.
Among the meroplankton, mollusk and crustacean larvae (nauplii, mysis, zoea and phyllosoma) showed the highest abundances (Fig.
The zoea 1 (Z1), zoea 2 (Z2), zoea 3 (Z3), zoea 4 (Z4), megalopa (Mp), and first crab (C) stages were fed, respectively, with Rotifer Brachionus plicatilis, early hatched Artemia sp., subadult Artemia sp., Artemia flake, and commercial shrimp feed with 35% protein.
