Seventy-five percent of the eggs were removed from the cloth substrate and 95% of them hatched. Sodium hypochloride at 5% concentration caused the failure of all the eggs to hatch but all of the egg were easily removed from the substrate. This method had reduced egg damage and collection time as compared to the conventional method whereby each egg was collected one by one
