aFigures presented in the table represent the number of age structure samples (specimens) retained at ODFW (Newport office); however, not all samples have been, or are even currently planned to be, examined for age determination. The figures for the number of samples are approximate only. In some cases, the number of samples for a year actually represents a series of years. For example, the 2,300 otolith samples of Dover sole in 1988 includes fish collected in 1986 and 1987. Age structures represent interopercles for English sole and otoliths for all other species.

bSpecies are as follows: Pac. oc. perch is Pacific ocean perch, widow is widow rockfish, yellowtail is yellowtail rockfish, canary is canary rockfish, S. thornyhead is shortspine thornyhead, L. thornyhead is longspine thornyhead, Arrowtooth is arrowtooth flounder, Dover is Dover sole, English is English sole, and Petrale is petrale sole.

cAgency denotes the fishery agency that collected and analyzed the age structure samples: WDFW is the Washington Department of Fish and Wildlife and NMFS is the National Marine Fisheries Service (Tiburon Laboratory).

dA year with a missing value denotes no age structure samples were collected for the given species.

eThe acronym Unk denotes the number of age structure samples for which the year of collection was unknown.

fAge structure samples from the most recent years are retained at WDFW (Olympia office).
