Transcriptome Analysis Reveals Molecular Underpinnings of Common Carp () Under Hypoxia Stress.

As an essential environmental factor that affects the economic benefits of aquaculture, hypoxia is one of the urgent problems to be solved in the aquaculture fish breeding industry. Common carp () is a critical economic fish in China, and at present, there are many breeding strains of common carp with different character advantages in China, including Hebao red carp ( var ) and Songpu mirror carp ( var ). Even if the environmental adaptation of common carp is generally strong, the genetic background of hypoxia tolerance in different strains of common carp is unclear yet.
