Oviparous fishes are known to posses two types of aromatase, which are ovary type and brain type . These aromatases play important roles in the reproduction of oviparous fish. however, little information is available on the role of aromatases in the reproduction viviparous fish. This study has been carried out to examine the changes of aromatase gene expression prior to and during vitellogenesis and during gestation in a marine viviparous fish, black rockfish, Sebastes schlegelii. The coding sequence of cyp19a1b gene cloned from rockfish brain was 1497 nucleotides . Rockfish cyp19a1b was more similar to cyp19a1b from other fish species than to rockfish cyp19a1a in amino acid sequence.
