wild goldfish

Where does the Wile Sea Carp fit into this family ?

I caught feral goldfish to 9 lb in the Delaware River. I also caught and removed hundreds of feral goldfish from Robert G. Martin Lake. I reported some of my catches to the Nonindigenous Aquatic Species Program at http://NAS.ER.USGS.GOV. I'll try to post a pic.

I am not kidding. Goldfish also known as crucian carp, is a prime food fish in Europe and Asia.

Crusians were brought over from Europe with common carp and mirror carp well over 100 years ago. In a lot of places they've been around longer than largemouth bass, brown trout, and rainbow trout. I've caught a lot of them all around NJ, lots of them in the Rahway River and ponds around it. They look a lot like common carp, the best way to tell the difference is common carp have barbels and crucians don't. Predators like to eat them too

no; different species

[zhitoman]

Technically they are different species, originally therm crucian carp was applied to gold crucian carp. In Europe there are two species of crucian carp, gold crucian carp and asian silver crucian carp. Goldfish are domesticated silver crucian carp. The thing is, those fish hybridize so much, it's not really possible to tell which one is a pure crucian now. You can trust me, I caught both species.

according to a couple articles linked from the wiki, it seems that the evidence points more towards the prussian carp these days?

Goldfish were bred from Prussian carp (Carassius auratus gibelio) in China, and they remain the closest wild relative of the goldfish. Previously, some sources claimed the Crucian carp (Carassius carassius) as the wild version of the goldfish. However, they are differentiated by several characteristics. C. auratus have a more pointed snout while the snout of a C. carassius is well rounded. C. gibelio often has a grey/greenish color, while crucian carps are always golden bronze. Juvenile crucian carp have a black spot on the base of the tail which disappears with age. In C. auratus this tail spot is never present. C. auratus have fewer than 31 scales along the lateral line while crucian carp have 33 scales or more.

they do look more like prussian carp than crucian carp
