Outline of Final Research Achievements

Generally, there are concerns about the risks of stocking and releasing animals to the wild, such as the breakdown of population structure, a reduction of genetic diversity, and the spread of diseases. This study aimed to collect helpful scientific knowledge for creating concrete guidelines based on the genetic diversity of corals in their natural state for appropriate and practical conservation activities. We assessed the genetic diversity and the proportion of clonal colonies of corals in farms in Onna Village, Okinawa Prefecture used microsatellite markers. Then, we compared them with that of the wild. In addition, single nucleotide polymorphisms (SNPs) were detected using MIG-seq methods. We conducted population genetic analyses of corals in Kumejima and kinship analyses of the coral colonies in the farms in Onna Village and the surrounding wild colonies.

Academic Significance and Societal Importance of the Research Achievements

サンゴ保全活動の長期モニタリング記録が少ないことが指摘される中、養殖サンゴの遺伝的多様性や、養殖サンゴが周辺の野生海域へ幼生供給基地としてどれくらいの効果があるのかを調べたことは保全活動の効果を知る上で意義があると考える。広範囲に渡る集団遺伝学的解析はソースシンクを調べる上で必須であるが、実際に保全活動が行われる地域的スケールの情報も重要である。MIG-seqで得られたSNPs解析の結果は島内という狭い範囲の遺伝的構造を明らかにするのに十分な解像度があることが確かめられた。
