Effect of photoperiod and temperature on development and growth of hepatopancreas of freshwater prawn Macrobrachium dayanum


Author(s): Pervaiz Ahmed Pervaiz, Madhu Sudan, Malabika Sikdar

Abstract: The effect of photoperiod and temperature on the development of Hepatopancreas was studied in laboratory for 30 days and divided into three different light regimes. 5 types of cells E-(embryonic) cells, F-(fibrillar) cells, B-(blister-like) cells, R-(resorptive/absorptive) cells and M-(myoepithelial/midgut) were found in Hepatopancreas of Macrobrachium dayanum. From the studies of histology and hepatosomatic index, (24L:00D) group showed an increase of the lumen of the tubules with a consequent compression of the epithelial cells, which formed a thin layer. In 24D:00L group illustrated cellular disruption, highest degree of abnormality with heamocytic infiltration and disrupted cells, disappearance of lateral cell membranes and lyses of cytoplasm in many areas. In control (12L:12D) prawns exhibited the well-organized glandular tubular shape normally seen in prawn species.
