“Histomorphological Changes In The Structure Of Y-OrganA Moulting Gland During The Annual Reproductive Cycle In The Fresh Water Crab Barytelphusa Guerini”

Abstract

Crustaceans are important constituents of aquatic ecosystems that provide a variety of ecological and economic services. Many crustaceans live in marine environments ,others in various freshwater systems and may be  used as biomonitors and bioindicators in various aquatic systems. The Y-organs of crustaceans are classical non-neural endocrine glands . They are paired and lobulated structures and are located ventrolaterally to the eyesockets. The Y-organs of crustaceans secrete ecdysteroids (moulting homone) which play a crucial role in the moulting and growth of crustaceans .The present study reveals the structural and histomorphological pattern of the Y-organ during the annual reproductive cycle.
