Because the zoea larvae in our study were fed at the same frequency, concentration, and type of food, the observed effects were likely caused by the different conditions of starvation experienced by the megalopae instead of the previous nutritional history of the zoeae. While the total developmental time of the preceding zoeal phase could also affect the MSD, this did not affect our study because the older and younger megalopae were distributed evenly among the treatments and control groups.
Zoeae (larval stages) are strong swimmers compared with most zooplankton, which allows the maintenance a position high in the water column (Epifanio 1995).
Females were maintained in a small aquarium with abundant and constant air flow, and after one week, a massive quantity of prezoeae and some specimens of zoeae I was released.

Nothing is known of the diet of jumbo squid paralarvae, but amphipods, copepods, and crab zoeae have been found in the digestive tracts of purpleback squid paralarvae (Vecchione, 1991); these and other zooplankton, as well as phytoplankton, also have been found in paralarvae of another ommastrephid, Illex argentinus (Vidal and Haimovici, 1998).
Once the eggs were hatched, the zoeae 1 (identified according to Shinkarenko [18]) were collected using 150 [mu]m mesh sieve and the most active ones (identified by their vigorous swimming activity in opposite direction in a whirl), from the same brood were stocked after rinsing in fresh seawater in 200 L rectangular FRP tanks at a density of 25 numbers/L (i.e.
