A system-of-equations approach to modeling age structured fish populations: the case of Alaskan red king crab, Paralithodes camtschaticus
Abstract: This paper presents a simultaneous system-of-equations approach to modeling age ... -structured populations using trawl survey age/size frequency data. The analysis builds upon a Ricker spawner ... properties of a delay-difference model. The framework shares a common spawner-recruit function across age ... age-structured population are retained through age-specific net survivability and growth parameters ...
