China discovers unique carp species

Chinese researchers have discovered a new species of carp, described as unique and endemic to Huizhou city, Guangdong province, inhabiting the upper reaches of rivers in the Pearl River basin.

Researchers said the fish's scientific name is Opsariichthys rubriventris. (Source: Xinhua).

In an article published in the international journal Diversity, researchers said this fish species, scientifically named Opsariichthys rubriventris , is distinguished by several characteristics, such as having 13-14 scales on the back, a lower jaw that protrudes beyond the upper jaw, and cheeks with two rows of vertical tubercles.

Additionally, adult males have reddish-orange coloration on the lower jaw, belly, pectoral fins, and anterior margin of the anal fin.

The discovery is important for understanding the evolution of the genus Opsariichthys and protecting fish diversity in the Pearl River tributaries, said paper co-author Zhou Jiajun.

According to the expert, this fish has a narrow distribution range and small population size. With its brilliant colors and high ornamental value, this fish is highly sought after in the aquarium trade.

However, in the context of overfishing affecting their habitat, this fish species needs more attention and protection.
