FIG. 3. Transfer of otoliths from the NOAA Fisheries AFSC to the UW Fish Collection. Survey-collected otoliths in Styrofoam boxes stacked 6 meters high (top left picture) and observer-collected otoliths in old cardboard boxes (center-left picture) stored in a World War II–era hangar at the AFSC. The otolith vials are transferred from Styrofoam boxes to new archival-quality cardboard boxes. Both boxes and lids are labeled to ensure no loss of data. Boxes are organized on new compactor shelves in a new storage facility at the UW. Specimen and locality data are entered in the collection database
FIG. 2 in Specimens by the Millions: Managing Large, Specialized Collections at the University of Washington Burke Museum Fish Collection
FIG. 2. Pathway of Early Life History collection specimens. First, plankton samples are collected by NOAA Fisheries AFSC FOCI (now the Recruitment Processes Program) scientists during annual surveys. Samples are then labeled and fixed in 3% formalin at sea. Next, samples are shipped to the Plankton Sorting and Identification Laboratory, Szczecin, Poland (ZSIOP), where they are sorted, identified, measured, and labeled. Larvae are placed in vials of 70% ethanol and eggs are placed in vials of 3% formalin. Labeled samples are then sent back to the AFSC for analysis. Quality control measures are in place to verify data and identifications. Samples are then transferred to the UW Fish Collection where they are cataloged and placed in cabinets. Specimen and locality data are entered in the collection database and uploaded to the online search engine at https://www. burkemuseum.org/collections-and-research/biology/ichthyology/collections-database/search.php. Specimen records can be downloaded and visualized with publicly available mapping software. Record shown is for Platichthys stellatus, UW 062774.
FIG. 1 in Specimens by the Millions: Managing Large, Specialized Collections at the University of Washington Burke Museum Fish Collection
FIG. 1. Pathway of specimens collected aboard NOAA Fisheries AFSC groundfish trawl surveys. First, specimens are collected from a haul. Next, specimens are labeled and photographed, tissues are taken and placed in 95% ethanol, and specimens are placed in 10% formalin. Specimens are then deposited in the UW Fish Collection where they are cataloged and placed in jars of 70% ethanol. Specimen and locality data are entered in the collection database and uploaded to the online search engine at https://www.burkemuseum.org/collections-and-research/biology/ichthyology/ collections-database/search.php. Finally, specimen records can be downloaded and visualized with publicly available mapping software. Record shown is for Sebastes wilsoni, UW 151346.
