ARSENIC-INDUCED ALTERATIONS IN GLYCOGEN AND LIPID DURING THE OVARIAN CYCLE OF A FRESHWATER SILUROID, MYSTUS (M.) VITTATUS (BL.)
AbstractHeavy metals get their way into the environment through a wide spectrum of natural and anthropogenic sources. Arsenic (As) has been reported to be present in main too different oxidation states (As3+ and As5+). Trivalent arsenic (As3+) has been reported to be more toxic than the pentavalent (As5+) one. Mystus (M.) vittatus, a siluroid fish, were exposed to Sublethal concentration (SLC) of As3+ to observe alteration in the glycogen and lipid content during three different phases of the ovarian cycle preparatory, spawning and post-spawning. The increasing order in the glycogen and lipid content was observed during the preparatory and spawning phase. Still, decrease in these biochemical parameters was during post-spawning phase of ovarian cycle in Mystus (M.) vittatus, a freshwater siluroid. Less significant alteration in glycogen and lipid was noticed after 15 days of exposure, but a highly significant decrease was observed after 30 days in SLC of trivalent arsenic as AsCl3. The causes for decline in these biochemical parameters have been discussed during the phases of ovarian cycle.
