Fin's Fish Guide
The False razbora (Pseudorasbora parva) is a brackish-water fish of the family Cyprinidae that grows up to 13 cm.
East Asia: from the Amur to the Pearl River basin in Siberia, Korea and China.
Description
The stone moroko is a small cyprinid (family Cyprinidae) growing to at most 12.5 cm. The slender, silvery-grey body has a superior, upturned mouth; juveniles and females show a dark lateral stripe, while breeding males darken and develop nuptial tubercles. Native to East Asia, the species has been widely introduced across Europe, where it is invasive, can displace native fishes and also spreads a harmful parasite. Males guard the eggs, which adhere to stones, until they hatch. Stone moroko eat small insects, fish eggs, fry and plant material, and the fish has no value as food.
