年の親魚資源量について、一般的に用いられている管理基準値と比較すると「減り過ぎ」、漁獲圧も一般的に用いられている管理基準値と比較すると「獲り過ぎ」の状態であるとされる。現行の保存管理措置に基づく漁獲シナリオでの親魚資源の将来予測では、低水準の加入が今後継続すると仮定した場合でも、2024 年までに暫定回復目標である歴史的中間値以上に親魚資源が回復する可能性が98%であるとされる。中西部太平洋水域では、1）親魚資源量を2024年までに、少なくとも60%の確率で歴史的中間値まで回復させることを暫定回復目標とする、2）30 kg未満の小型魚の漁獲量を2002～2004年平均水準から半減させる、3）30 kg以上の大型魚の漁獲量を2002～2004年平均水準から増加させない、等を内容とする保存管理措置が採択されている。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"1.
