Considering the metabolic shifts in freshwater bivalve shell fishes, due to neuro-endocrine stress we report here the seasonal variation in ascorbic acid content from mantle, hepatopancreas, gonad, foot and gill of adult freshwater bivalve Lamellidens marginalis, collected from Kaigaon during winter (December-January).Adult bivalves of approximately same size were distributed in four group 1st treated as control 2nd as cerebral ganglia ablated 3rd as dist water injected and 4th as cerebral ganglionic homogenate injected. The ascorbic acid content was determined on 5th and 10th day from mantle, hepatopancreas, gonad, foot and gill different group. On 5 th day, the ascorbic acid content was significantly decreased from mantle in both cerebral ganglia ablated and ganglionic extract injected group respectively. While the content from gonad showed significant increase in ganglionic extract injected group On 10th day the ascorbic acid Content was significantly increased from hepatopancrcasand in cerebral ganglia ablated and ganglionic extract injected group respectively The content from gonad was also significantly increased in cerebral ganglia ablated and in ganglionic extract injected group The result are discussed in the light of metabolic shift in the bivalves due to neuro-endocrine manipulation.
