The interactive chart is auto generated from the AFSC/REFM: Flatfish maturity near Kodiak, 2012-2013 dataset that is comprised of individual fish records from collections made during port sampling at Kodiak Alaska for the purpose of updating maturity estimates for selected GOA flatfish. The collections were made by an Alaska Fisheries Databank funded sampler. Sample preparation, ageing and histological determination of maturity state were completed by AFSC staff.
