ゲノム資源学、個体数推定、有効集団サイズ、有効繁殖集団サイズ、近親標識再捕法

抄録

本稿では、ゲノム情報を用いた個体数推定手法について、水産資源学への応用を念頭に概説した。共通祖先までの時間、共有配列の長さ、遺伝的浮動、近親関係という4つの観点から、有効集団サイズ（N_e）、有効繁殖集団サイズ（N_b）、親個体数（N）などの推定原理を整理し、それぞれが反映する時間スケールや必要データの違いを解説した。また、近親標識再捕（Close-Kin Mark-Recapture、CKMR）法を中心とした資源評価モデルや管理方策検討への応用についても紹介し、ゲノム情報が今後の水産資源学における重要な情報基盤となる可能性を論じた。
