Conservation Minister Gord Mackintosh says Delta Marsh is one of the world’s greatest marshes which scientists have described as being the "kidneys" of the province.
The new project will see fish screens put up to keep the invasive and destructive fish species known as common carp from entering Delta Marsh.
Common carp are native to Asia and parts of Europe.
They are large bottom-dwelling fish that disrupt entire wetland ecosystems by regularly rooting up vegetation and stirring up silt and sediment, which stops sunlight from reaching other aquatic life.
Mackintosh says research has shown vegetation will recover if the carp are prevented from entering the marsh during the late spring and summer, as they do not overwinter in the marsh.
