  After mating, the eggs were deposited, or oviposited, on setae of the pleopods of the female. The newly oviposited eggs were containing all the necessary material for synthetic processes associated with embryogenesis and morphogenesis and all the compounds required for oxidative metabolism and energy production. The fertilized eggs were opaque, greenish, round or oval in shape. The diameter of the egg was approximately 0.45 mm. As the development progresses, the greenish colour changed into light green, brownish-yellow and finally to dull whitish in colour about to hatch. The incubation periods varied from 12-14 days. The process of embryonic development includes nuclear division, cleavage (blastomeres), segmentation, formation of optic vesicle, eye pigment development and larva formation. At third minute after mating the sperm fused with the egg membrane and subsequently the male pro.. View More»
