Goldfish
The goldfish ("Carassius auratus") is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is one of the most commonly kept aquarium fish.
Goldeye
The goldeye is considered a good fly-fishing fish, but not popular with most anglers because of its small size. It is one of 122 new species of animals, birds, fish documented by the Lewis & Clark Corps of Discovery. Commercial fishing of this species was reported as early as 1876. Its fresh flesh is soft and unappealing, so it was only taken randomly in gillnets and (in the past) sold for dogfood. They are now sought after by many consumers as a smoked fish. Many commercial fishermen sell them smoked after being processed (marinated) in a brine made of spices, salt, brown sugar, and other secret ingredients. They are smoked in oak wood, apple wood, or other woods. Each producer has their own ways of smoking. Despite its soft flesh the goldeye may be soaked in a salt brine for 24 hours and then poached, firming up the flesh.
