Each year over 50 Alaskan groundfish stock assessments report the condition
of Alaskan fisheries resources in the U.S. Exclusive Economic Zone.
Stock assessment scientists integrate biological
observations and theoretical considerations via population modeling techniques to produce
population dynamic trends and biological yield estimation.
This data set captures various stock assessment trends and estimations.
Stock assessment values serve as a record of the analysis used for management in each year.
