History
sources claim that crucian carp (Carassius carassius(karuss) is the wild version of the goldfish.
-Research by Dr. Yoshiichi Matsui, a professor of fish culture at Kinki University in Japan, suggests that there are small differences that demonstrate that crucian carp is the ancestor of the common goldfish, they have sufficiently diverged to be considered separate species (Pearce 2006).
Others hold that the wild form of the goldfish (Carassius auratus auratus) is Carassius auratus gibelio, or rather Carassius gibelio with auratus as the subspecies.
-The different species can be differentiated by the following characteristics:
C. auratus has a more pointed snout while the snout of a crucian carp(goldfish) is rounded.
-The wild form of the goldfish C. auratus gibelio or C. gibelio often has a gray/greenish color, while crucian carps are always golden bronze.
-Juvenile crucian carp (and tench) 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.
The goldfish was first domesticated in China (BAS 2007). During the Tang Dynasty, it was popular to dam carp in ponds.
-It is believed that as the result of a dominant genetic mutation, one of these carp displayed gold (actually yellowish orange) rather than silver coloration.
- People began to breed the gold variety instead of the silver variety, and began to display them in small containers.
-The fish were not kept in the containers permanently, but would be kept in a larger body of water, such as a pond, and only for special occasions at which guests were expected would they be moved to the much smaller container (BAS 2007).
In 1162, the empress of the Song Dynasty ordered the construction of a pond to collect the red and gold variety of those carp.
-By this time, people outside the royal family were forbidden to keep goldfish of the gold (yellow) variety, yellow being the royal color.
-This probably is the reason why there are more orange goldfish than yellow goldfish, even though the latter are genetically easier to breed (WetPetz 2004).
-The occurrence of other colors was first recorded in 1276. The first occurrence of fancy tailed goldfish was recorded in the Ming dynasty.
Around the sixteenth century or beginning of the seventeenth century, goldfish were introduced to Japan (BAS 2007), where the Ryukin and Tosakin varieties were developed.
-In 1611, goldfish were introduced to Portugal and from there to other parts of Europe (BAS 2007). Goldfish were first introduced to North America around in the mid to late 1800s and quickly became popular in the United States (Brunner 2003; BAS 2007).
