Abstract :

Considering the metabolic shifts in freshwater bivalve molluscs due to neuro–endocrine stress, we report here the seasonal variation in lipid content from mantle, hepatopancreas, gonad, foot and gill of adult freshwater bivalve Lamellidens corrianus collected from Jayakwadi backwaters of Godavari river at Paithan during summer (April–may). Adult bivalves of approximately same size were distributed in four aquaria, Ist treated as control, 2nd as cereal ganglia ablated, 3rd as dist. water injected & 4th as cereal ganglionic homogenate injected. The variation in the lipid content of L. corrianus from different groups on 2nd, 7th and 12th day during three summer seasons were estimated. During summer season the lipid content in the foot was significantly decreased in cereal ganglia ablated group and significantly increased in cereal ganglionic extract injected group on 7th day. The content was significantly increased in the gonad of both ablated and injected group on 7th day. On 12th day the content significantly increased in foot and gonad of both groups. The results are discussed in the light of metabolic shifts in the bivalves due to neuro–endocrine manipulation.
