Abstract
Significant alterations in the ionic composition of blood were recorded in Oreochromis mossambicus exposed to sublethal and lethal concentrations of endosulfan. Dysfunction of osrnoregulatory processes was manifested by the increased levels of serum sodium, potassium and chloride and decreased levels of phosphate and bicarbonate.This calls for careful application of pesticides in plant protection operations to ensure proper protection of fishery resources.
