COPPER SULPHATE |

Blue crystalline solid
NARSIPUR’s Copper Sulphate is used for the treatment of some diseases of fish such as for the treatment of bacterial gill diseases and so also for some protozoa and fungal infection.
METHOD OF APPPLICATION
Used at a rate of 500 ppm as dip for one minute. Should be used in well buffered water only as toxicity can occur in poorly buffered water. Some recommend use as a bath for upto 30 minutes with dosage rate of 0.5% ppm for poorly buffered water and 2 ppm for well buffered water.
In bad outbreak of external bacterial and protozoal diseases, Copper sulphate is used for longer period (several hours) at 0.2 ppm. This is only recommended in well buffered waters.
Also used in some areas for the eradication of snails from water course, to break the life cycle in some flukes ( such as eye fluke – diplostomum, spathacaeum). Usually requires long exposures (over one hour) as snails will retract in to their shells and appeared to be poisoned only to come alive again once the copper sulphate has passed. Also used as a herbicide to control algae. Applied at 0.5 - 1 g / m3 in pH < 7, to 1.5 g / m3 in pH > 7. Toxic to fish there fore only ¼ - 1/3 pond should be treated at a time.
Copper sulphate is used to treat a variety of external parasites of fish. It is also an effective algaecide and piscicide , it can kill an aquatic plants and fish and is approved for use as an algaecide. The relationship between toxicity of Copper suphate and alkalinity of the water is very important. (Alkalinity is the total concentration of alkaline substances in the water expressed as equivalent calcium carbonate). In water with an alkalinity less than 50 mg / l , Copper sulphate can be toxic to fish and it should not be used unless a bio assay has been run in the water first with a limited number of the fish to be treated. The following general guidelines have been established for the use of Copper sulphate.
