“…The major sites of glycogen storage in the mussel are the mantle, hepatopancreas, labial palps and Leydig cells of the visceral mass. Similar localization of glycogen has been reported for the fresh water mussel Parreysia cormgata (Nagabhushanam and Lomte, 1971).…”

Biochemical and histochemical techniques were employed to study tissue distribution, and concentrations of carbohydrate reserves and phosphatase activity in uninfected Mytilus edulis and specimens parasitized byProctoeces maculatus. Glycogen was stored in the mantle, hepatopancreas, labial palps and mesosomal Leydig cells of the mussel, and in the body parenchyma of post-miracidial stages of the trematode. The glycogen content of the mantle and hepatopancreas increased steadily from January to a maximum level in June and then declined sharply to a minimum level in December. No differences were observed in the annual glycogen cycle of infected and uninfected mussels. Starvation of mussels at a temperature conducive to high metabolic activity of the worms resulted in a rapid decline in the glycogen content of infected mussels by the first week of starvation. A stable glycogen concentration was maintained for 4 weeks by starved uninfected mussels. The distribution of acid phosphatase activity in the tissues ofM. edulisandP. maculatuswas greater than that of alkaline phosphatase activity, but increased alkaline phosphatase activity was observed in the haemolymph of mussels infected with adultP. maculatus.

“…Relatively large variation in meat content occurs in bivalve molluscs depending upon the variation in physiological condition and environmental variables (Wilbur and Owen 1964). The biology of freshwater mussels viz., Parreysia corrugata Lomte 1971, Lomte andJadhav 1980) Parreysia favidens (Ramesha and Sophia 2015) and Lamellidens spp. (Narian 1972, Nagabhushanam and Lohgaonker 1978, Moorthy et al 1983 inhabiting in the freshwater habitat have been reported previously.…”

Growth, morphometry and length-weight relationships of the freshwater mussel Lamellidens marginalis (Lamarck, 1819) was studied during January 2014 and May 2015. Sampling was carried out monthly and a total of 560 specimens were collected from Rajshahi district, northwest of Bangladesh. The recorded length -breadth and length-width relationships were B = 0.179 + 0.475L and W = 0.196 + 0.3163L respectively. The length-total weight, length-wet tissue weight, length-dry tissue weight, length-shell weight, length-dry shell weight relationships were W = 0.1241L2.9066, W = 0.0524L2.7377, W =0.0116L2.7849, W = 0.0533L2.9178 and W = 0.0391L3.0386 respectively. Monthly b values of length-lengths and length-weights relationships indicated a negative allometric growth pattern except length-shell weights relationships which showed an isometric growth of the mussel. This study is the first report on growth pattern of Lamellidens marginalis from Bangladesh and the results would be useful for fishery managers to impose adequate regulations for a sustainable fishery management of this species in the freshwater ecosystem in Bangladesh.

“…A decrease in the glycogen content due to starvation was reported by Nagabhushanam (I96 i) in Martesia striata, Towle & Giese (1966) in P. agassizii and by Nagabhushanam & Lomte (1971) in Parreysia corrugata. An increase in water content due to starvation was found by Steeves (1963).…”
