Different physiological and morphologically changes were observed in experimental animals it includes protective response, foot movements and its secretion, response to external stimuli, mucus secretion of gills and diapedesis. In this concept to improve that any toxicants or any molluscicide were responsible for the alternations in behavioural of animal body. From obtained results, we concluded the toxicity of mercuric chloride was responsible for the behavioral changes in freshwater bivalve mollusks L. marginalis.

The bodies of protozoan are morphologically a single cell and manifest all characteristics common to the living thing. The various activate which make up the phenomena of life are carried on by parts within the body or cell. These parts are comparable in function with the organ of metazoan which is composed of a large number of cells grouped into tissues and therefore called organelle. The biodiversity of protozoa changes from place to place and time to time, because of environmental make-up. Their presence, absence classifies the water quality. Protozoans are free living as well as parasitic. Free living protozoan are present in vast number in nature and in great variety of habitats. The minute size, multiplication condition.

It is good source of vitamin- C. Black mold caused by Aspergillus niger is a major storage problem of amla. Hence amla are significantly damaged and destroyed by A. niger during storage.To evaluate efficacy of different plant extracts in inhibiting colony growth of A. niger more or less in varying degrees.Among the 10 th plant extracts tested against A. niger, Tinospora cordifolia (78.10%) were significantly superior over all other plant extracts. Next best was Boerhavia diffusa (72.45 %), Ocimum santum (71.oo%),s Tribulus teristrie (62.18%), Adathoda vasica showed less inhibitory effect (6.60%).

The behavioral changes were more pronounced in summer and winter than in monsoon. The study revealed that the mussels are more sensitive to cadmium toxicity in summer, while they are more resonated in winter.

C. nocturnum leaves extract shows the remarkable piscicidal activity. It shows there was significant negative correlation between LC50 values and exposure periods when observed till 72 hr. During the toxicity experiment the fish shows the behavioral changes such as suffocation, rapid movement, and spiraling and convulsion period to death. Piscicidal activities show their dependence with concentration and time. This piscicidal activity may be due to their adverse effect on respiratory as well as energy production of fish. During bioassay experiments, a phenomenon of recovery was observed in stupefied fishes when fishes were shifted to untreated water after showing a partial symptom of death at LC100 dose. This indicates the tolerance and detoxifying capacity of fish to toxic principal. This nature of the fish stupefying propert...

In control group the content was high from posterior adductor muscle (1.897±0.036). In Lc0 group when compared to control group the content was high from gonad (209.25% p< 0.001). In Lc50 group content was high from gonad (138.43% p< 0.001) when it was compared to control group. On the other hand when compared to Lc0 group show significantly increased from gill (41.75% p< 0.001).

Lamellidens marginalis in respective groups i.e. control, Lc0 and Lc groups. In control group the content was high from gill (1.7674±1.1503). In Lc group when compared 50 0 to control group the content was high from adductor muscle (522.66% < 0.001). In Lc group content was high 50 from whole body (670.09% < 0.001) when it was compared to control group. In Lc group when compared to 50 Lc group show significantly high from anterior adductor muscle (45.38% < 0.001). 0

The results showed that glycogen content was significantly disturbed in all the body parts of Lamellidens marginalis studied after exposure to cadmium chloride (LC0 & LC50). The disturbance in the glycogen level is one of the outstanding biochemical lesions due to the action of cadmium. There is a significant decrease in glycogen profiles in different body parts after exposure to lethal concentration of cadmium under stress conditions. This might be due to increase in glycogenolysis by increase in phosphorylase enzyme activity and elevation of succinate and pyruvate dehydrogenase leading to anaerobic metabolism during anoxic stress conditions ...
