| Research Abstract |
This study evaluated the genetic diversity of captive bamboo rockfish, sebastes oblongus, which was one of the target species of stock enhancement project in Seto Inland Sea. According to the paternity analysis, the number of male fish which one wild and one reared female mated was about only 1.2 and 1.5, respectively. We developed the artificial insemination of viviparous fish in this study to protect a decrease in genetic diversity of released fish. The artificial insemination was effective from early October to late November and required the urine of male fish to activate the sperm. It was effective in increase in the family numbers and conservation of the genetic diversity to conduct the artificial insemination.
