Effect of aluminium phosphide on some metabolites of the liver and muscle of Parophiopcephalus obscurus

Abstract

Aluminium phosphide induced changes in some metabolic parameters in Parophiocephalus obscurus were assessed. Parophiocephalus obscurus (mean length, 18.00±0.09cm and mean weight, 65.03±0.03g) were acclimatized to laboratory condition for 10 days and then exposed to varying sublethal concentrations of aluminium phosphide (4.20, 6.30, and 8.40mgl^-1) in semi-static bioassay for 14 days. A concentration dependent effect was observed in liver total protein and albumin in the muscle. Total protein values obtained in the muscle were not statistically significant (p<0.05), albeit a slight decrease in values was observed at 4.20 and 8.40mhl^-1. Based on the results, aluminium phosphide used for agricultural and anthropogenic purposes could have a serious effect on fishes such as Parophiocephalus obscurus.
