Lake Kasumigaura
A variety of fish can be caught from the waters of Lake Kasumigaura, including smelt, Japanese icefish, crucian carp, goby, Japanese eel and river prawn. The most popular catch is cultivated carp, followed by smelt and goby. Another cultivated treasure from Lake Kasumigaura is the beautiful Kasumi freshwater pearls. They were known for their high luster and rosy hues, which is the result of a four-year cultivation period. However, in 2006, cultivation was discontinued as cheap freshwater pearls from China proved too difficult to compete against.
