Ever wonder if walleye pollock born during the Carter administration have the same average length-at-age as pollock born during the Bush administration? Do southern rock sole grow faster than northern rock sole? Do pollock from Shelikof Strait live longer than pollock from Nagai Strait? These questions and more can be answered on the AFSC Age and Growth Interactive Mapping Application. Draw circles around haul locations and have an age-length scatterplot and a mean length-at-age automatically graphed. Multiple areas and years of collection can be selected and color coded for comparing fish growth. Data collected over 30 years is available for 40 different species of groundfish from the Bering Sea, Aleutian Islands, and Gulf of Alaska. New age data is added semiannually, typically in April and October.
