| Descripción: | Stages from oviposition to veliger hatching are described for Strombus pugilis under laboratory conditions. Two egg masses from Playa Seyba, México, (20"45' N, 91°45' W) were used (three sub-samples per mass). Each sub-sample was immersed in a 11 container at 29 ± 1°C. This description is based on stages known from Strombus gigas, which include number of: fertilized eggs, morulae, gastrulae; trochophore larvae with slow movements, larvae with primordium foot, larvae with eyes, larvae with statocyst and veliger larvae. Eggs with first division appeare d five hours after oviposition in the three replicates of each mass, although in greatest number in one of the egg masses. Trochophore larvae with slow movements appear after 50-54 hours and veligers hatch after 90 hours. |
