Проведен ряд численных экспериментов с различными вариантами модели для пополнения. Результаты выполненной работы могут быть использованы при подготовке прогнозов ОДУ морских промысловых рыб при условии, что данные наблюдений позволяют использование структурированных по возрасту моделей в пространстве состояний.</p></abstract><trans-abstract xml:lang="en"><p>Results of using a state-space cohort model with smoothing unscented Kalman filter for assessment of Pacific cod stock abundance and the other population parameters in the Petropavlovsk-Komandorskaya Subzone are presented.
