An investigation has been conducted on the Gho-Manhasan stream of Jammu region from Dec 2014- Nov 2015 with an aim to work out the various breeding related changes in the Himalayan prawn Macrobrachium dayanum. During this period, certain important periodical modifications were found likely as the presence of extra setae especially for the purpose of egg bearing. The special breeding dress came into being after the pre-breeding moult. The eight groups of breeding setae have been observed as Simple setae, Pappose setae, Spiniform setae, Protective setae, Plumose setae, Serrate setae, Multidenticulate setae and Ovigerous setae. https://www.biotech-asia.org/vol14no4/presence-of-various-type-of-setae-as-a-periodical-modification-in-himalayan-prawn-macrobrachium-dayanum-from-jammu-region/ Macrobrachium Dayanum; Breeding Dress; Setae
