15 specimens (105-120 mm, TL) of the serranid fish Arabian perchlet Chelidoperca occipitalis Kotthaus, 1973 were collected from Visakhapatnam fish landing centre, east coast of India. C. occipitalis is body pinkish in colour with a dark band along preopercle margin to caudal. Yellowish spots on dorsal, caudal and anal fins. 44-46 lateral line scales are present. The morphological characters along with their body colour patterns are described. This is the first record of the species from Visakhapatnam coastal waters, east coast of India.

The liver of platy Xiphophorus maculatus is single lobule organs, which have no regular cords of hepatocytes and exhibited basophilic feature in fresh specimen. Platy was treated with 5&10 ppt salinity in addition to control treatment for over 70 days. Fishes were kept as dynamic specimens up to the expiry of experiment. Captive fishes showed little degenerated hepatocytes and scarcity of macrophage aggregates which increased along progressive period. In 5ppt treatment, hepatocyte density increased after 30 days, with more degenerated cells and larger slits among parenchyma as more bile stagnation. Noticeable alterations started within 10 days of exposure. There were increments in slits, spots of necrosis and black macrophage aggregates as well as increased cell density. With progressive period, there were increasing degeneration, blood infiltration and biliary stasis. The capsule remained surrounding the liver mass in all treatments, as there was an active circulation so as pancreatic tissue up to expiry of experiment.
