      關(guān)鍵詞:觀賞魚(yú)句首基因突變

      錦鯉在生物學(xué)上屬于鯉科,鯉科為魚(yú)類(lèi)中最大的一科,分布很廣,是一種高檔觀賞魚(yú),有“水中活寶石”“會(huì)游泳的藝術(shù)品”的美稱(chēng)。

      A fish represents wealth and prosperity because the actual word in Chinese for fish means “abundance”. Twin golden carp swimming atop a golden yuanbao is an even better sign. As with most Chinese symbols, the carp(鯉魚(yú)) has a legend attached to it. According to the legend, the carp is noted for its strength and bravery because it swims against the current, upwards, “mastering” falls and ending up at a gate on the Yellow River called Dragon Gate. The carp turns into the revered Celestial Dragon when it makes a final leap over the last rapids.

      Based more on facts, the carp was held in ponds during the Tang Dynasty (618—907 AD). As a result of a dominant genetic mutation(基因突變), some of these carps displayed a gold(actually yellowish orange) rather than a 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 in a larger body of water, such as a pond. Only for special occasions when guests were expected would the fish be moved to the much smaller container.

      In 1162, the Empress of the Song Dynasty(960—1279 AD) ordered the construction of a pond to collect the red and gold variety of those carp. By this time, people outside the imperial family were forbidden to keep goldfish of the gold (yellow) variety, yellow being the imperial color. This is probably the reason why there are more orange goldfish than yellow goldfish, even though the latter are genetically easier to breed.

      The occurrence of other colors was first recorded in 1276. The first occurrence of fancy tailed goldfish was recorded in the Ming Dynasty (1368—1644 AD).
