    The fine structure of the egg envelope and micropyle of unfertilised spawned eggs of rohu (Labeo rohita) was observed using scanning electron microscope (SEM). The outer surface showed regularly arranged pores (dia. 0.20 - 0.25 μm) but was devoid of any filaments, fibrils or wrinkles. The micropyle was funnel shaped which exibited an outer pit (10 μm dia.) narrowing into a distinct canal (4.5 μm dia.). The larger diameter of the micropylar canal in comparison with the sperm head size of rohu and some other cyprinids make intergeneric and interspecific hybridisation easy in rohu.
