“…Seasonal changes, which are difficult to distinguish from changes related to the reproductive cycle, have been observed frequently (Ansell, 1974;Ando et al, 1976;Balasubramanian et al, 1979;De Moreno et al, 1976a, 1980Desai et al, 1979;Nagabhushanam and Deshmukh, 1974;Nagabhushanam and Dhamne, 1977;Nagabhushanam and Talikhedkar, 1977;Nagabhushanam and Mane, 1978;Pollero et al, 1979;Swift et al, 1980). From the data on Mytilus viridis (Mane and Nagabhushanam, 1975), an inverse relationship between the lipid content of digestive gland and gonad can be deduced.…”

“…Seasonal changes in the activity of neurosecretory cells are also associated with gonadal development, and the cells release their products at maturity stage [96]. Moreover, number of active neurosecretory cells positively correlates with progress of the gonad development in the Bay scallop [95], clam (Katelysia opima) [100], blue mussel [101], and greenlipped mussel (Perna canaliculus) [102].…”

It has been observed that 5-HT excites the heart nerves in hard clam and regulates contraction and relaxation of the anterior byssus retractor muscle in the blue mussel. It is now known that 5-HT regulates several neurobehavioral systems such as mood, appetite, sleep, learning, and memory. It also plays critical roles in the physiological functions of peripheral organs involved in stress, growth, and reproduction in the animal kingdom. The present study reviews conserved 5-HT biosynthesis and its localization in the nervous system, and its physiological contribution to regulate reproduction in bivalves. In the cytosol of neurons, tryptophan hydroxylase catalyzes hydroxylation of l-tryptophan to 5-hydroxytryptophan, which is converted to 5-HT by aromatic l-amino acid decarboxylase. A 5-HT transporter and a monoamine oxidase reuptakes and metabolizes 5-HT to control the amount of released 5-HT in the nervous system and peripheral organs. Perikarya and fibers of 5-HT neurons are mostly located in the cortices and neuropil of ganglia, respectively, and innervate the gonad. However, distribution and 5-HT content differ among species and sexes and undergo seasonal variations associated with gonadal development. The present review pays a special attention to future research perspectives to better understand 5-HT regulation of reproduction in bivalves.

The present study was conducted in the Bakkhali river estuary, Cox's Bazar, Bangladesh from September 2012 to July 2013. Percentage of protein was the main component of the biochemical composition in the mussels followed by carbohydrate, ash, and lipid. The proximate composition of Meretrix Meretrix revealed that it contained protein (12.184-14.291%), lipid (0.721-0.922%), ash (2.435-3.201%), moisture (77.0-78.9%) and carbohydrate (4.914-5.907%). The mineral content of the Meretrix Meretrix were Ca (0.601-0.801 mg/g), Fe (0.070-0.099 mg/g) and phosphorus (0.300-0.794 mg/g). In the present investigation, the seasonal changes of protein and lipid were found to follow a similar pattern. Hence, a signifi cant positive correlation was found between the percentage of protein and lipid in Meretrix meretrix. A positive relationship was found between the percentage of protein and lipid, protein and ash and, lipid and ash. A signifi cant inverse correlation was found between protein and carbohydrates, carbohydrate and lipid and between carbohydrate and ash content of dry tissue of Meretrix meretrix (p<0.01). Further study on Meretrix meretrix should be carried out since their acceptability to the coastal dwelling community.
