Team investigates population genetic characteristics of two hybrid crucian carp strains

The crucian carp (Carassius auratus) is a common freshwater fish species in China, and its aquaculture mainly depends on excellent varieties through artificial breeding. The hybrid strain derived from Carassius cuvieri (♀) × C. auratus red var. (♂) (HFJ) and the new homodiploid crucian carp-like strain derived from Cyprinus carpio (♀) × Megalobrama amblycephala (♂) (NCRC) are important germplasm sources of crucian carp.
