Abstract:

The aim of the present investigation was to study the toxic effect of a synthetic pyrethroid cypermethrin on glycogen levels in vital tissues (gill, muscle, brain, liver and kidney) Labeo rohita after exposure to sub lethal concentrations (0.226, 0.453, 0.679 and 0.906µg/L representing 5, 10, 15 and 20% of 96h LC50 value i.e 4.53µg/L) of cypermethrin for three different exposure periods, 1, 2 and 3 weeks. It was found that the glycogen content was reduced in all the tissues under sub-lethal concentrations of cypermethrin at 1, 2 and 3 weeks. Reduction was observed in all the tissues tested at all the concentrations and exposure periods. Reduction in glycogen content was maximum (45%) in liver and minimum (13.08%) in brain at 0.906µg/L at 21 days. It was observed that all the alterations were dependent on concentration as well as exposure period.
