A system-of-equations approach to modeling age structured fish populations: the case of Alaskan red king crab, Paralithodes camtschaticus
-structured populations using trawl survey age/size frequency data. The analysis builds upon a Ricker spawner ... -recruit structure and provides a cohort-based estimation method that retains the underlying dynamic ... properties of a delay-difference model. The framework shares a common spawner-recruit function across age ... -class equations. This exploits the commonality among cohort members and serves as an instrumental ...

Tests for anomalous years in the CCAMLR index series (draft)
Abstract: The properties of a method for detecting anomalous years in CCAMLR index series are ... obtained on the assumption that the series being considered consists of random values from a constant ... normal distribution. This idea is extended to situations (a) where the series values are still normally ... distributed, but contain a linear trend and autocorrelation, and (b) where the series values are from some ...
