Effect of aluminium phosphide on some metabolites of the liver and muscle of <i>Parophiopcephalus obscurus</i>

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.
