Details

There are two datasets included: chinook-month and chinook-year. The monthly data are available from 1990 and the annual data are available from 1950. From the NOAA Fisheries Statistics Divison: "Collecting these data is a joint state and federal responsibility. State-federal systems gather landings data from state-mandated fishery trip-tickets, landing weighout reports from seafood dealers, federal logbooks of fishery catch and effort, and shipboard and portside interviews and biological sampling of catches. State fishery agencies are usually the main collectors of these data, though they and NOAA Fisheries gather data jointly in some states. Surveys are done differently in different states; NOAA Fisheries takes supplemental surveys to ensure that the data from different states and years are comparable."

In addition from NOAA Fisheries Statistics Division: "Statistics for each state represent a census of the volume and value of finfish and shellfish landed and sold at the dock, not an expanded estimate of landings based on sampling data. The main statistics collected are the pounds and ex-vessel dollar value of landings identified by species, year, month, state, county, port, water, and fishing gear. Most states get their landings data from seafood dealers who submit monthly reports of the weight and value of landings by vessel. Increasingly, though, states are getting landings data from mandatory trip-tickets—filled out by seafood dealers and fishermen at the end of every fishing trip, indicating their landings by species."
