Portunus pelagicus Linnaeus, 1758 is an important candidate species for culture in India and trials are for developing its
hatchery technology. The present work investigates the changes occurring in diameter, volume, wet weight and morphology
of P. pelagicus eggs during incubation which would improve the knowledge base on embryology of species. Mated females
from wild were maintained under similar physico-chemical conditions. Once spawned, the egg samples were collected from
each animal daily and their diameter, volume, and wet weight were assessed. Based on the changes occurring in egg
morphology at 24 hour intervals, the embryo development was classified into eight ‘periods’. The egg size and wet weight
varied significantly (P
