Sebastes chrysomelas

Sebastes chrysomelas, commonly known as the black-and-yellow rockfish, is a marine fish species of the family Sebastidae. It is found in rocky areas in the Pacific off California and Baja California. Although it is similar in appearance to the China rockfish, it lacks the China's long yellow streak. Its distribution is also more to the south than the China.[2]

The black-and-yellow rockfish has speckles that are similar to the China rockfish, but lacks the long yellow streak starting at the foredorsal fin curves.[2]

Genetics

A potential PCR-RFLP genetic sex marker developed for gopher rockfish.[3] In the original study, the marker was able to successfully distinguish male and female black-and-yellow rockfish,[3] but it was unsuccessful in a subsequent study using the same method.[4]
