Abstract

Heavy metals are amongst the most toxic pollutants that have particular importance
due to their side effects and bioavailability to different species of aquatic animals
and entry into the food chains. Chitosan is a bio-polymer that has been extensively
used in food industries and has showed specific characteristics to combine with
metal ions. Therefore, it have a potential to be used for reduce bioabsorption of
heavy metals . For this purpose, 180 common carps were subjected to 6 treatments
including: control, cadmium 250, cadmium 125, chitosan + cadmium 250, chitosan
+ cadmium 125 and chitosan only classified and reared for a period of 21 days.
The fish were then transferrred to the normal condition for a week as a recovery
period. Results showed that albumin, triglyceride, glucose, creatinine, AST, ALT
and ALP were significantly increased in treatments that received cadmium only
(250 and 125) in their food. Meanwhile, above indices did not changed in
treatments that received chitosans. Total antioxidants and malondialdehyde in
cadmium-only treatments were significantly decreased and increased, respectively
compared to the control in liver, kidney and gill tissues
