ケガニは重要な資源であるが、年齢形質が無いために体長ベース解析が不可欠である。本研究では、ケガニ用に改訂された体長ベースモデルを用いて道東沿岸のゲガニの資源量推定を行った。その結果、モデルとデータの当てはまりはよく、資源個体数は70万〜210万個体と推定された。 (TM)

年齢ベースモデルによる解析が広く用いられているが、漁獲や成熟等は体サイズに依存することから、体サイズベースの資源評価が合理的である。本研究では、体サイズにもとづくYPRとSPR解析法を開発し、北海道沿岸のスケトウダラに適用した。その結果、年齢もとづく結果と遜色ない結果が得られることが分かった。 (TM)

魚類の成長には大きな個体差があるが、資源管理モデルでは一般に考慮されていない。そのため、漁獲の体長選択性を通じて、成長個体差が管理効果に与える偏りが懸念される。本研究ではシミュレーションにより、成長個体差がYPR解析や%SPR解析結果に与える偏りについて評価した。その結果、個体差が大きくなるにつれ、YPRは過小評価、SPRは過大評価される傾向があり、成長の個体差を考慮した解析の必要性が示唆された。 (TM)
