    • Obsolete - AFSC/RACE/EcoFOCI - Ichthyoplankton data collected in support of FOCI assessment surveys and ecosystem observations in the Bering, Beaufort, and Chukchi Seas and the Gulf of Alaska 1972 to Present

    Metadata Updated: April 1, 2024

    The dataset contains records of fish eggs and larvae collected during FOCI assessment surveys. Records include all data pertinent to identify where specimens were collected (lat, lon, date, gear used, max depth of gear, water depth). Specific data on specimens includes scientific name, stage of development, number collected (whole numbers and CPUE), lengths of larvae, and diameters and stages of eggs. In addition, there are comments that explain any irregularities that may have occurred during sample collection; depending on the reason data is being extracted, comments may indicate a sample is not suitable for consideration.

It is the responsibility of the user to determine whether or not the data is suitable for the intended purpose.
    Lineage Processing for an ichthyoplankton cruise is carried out in several steps: measuring the volume of the plankton in each sample, sorting out and counting all fish eggs and larvae, measuring fish larvae, identifying all fish eggs and larvae, staging (aging) some fish eggs, and putting fish eggs in 5% Formalin and larvae in 70% ethanol (mixed from 95 % ethanol with no additives). Results are returned in an SQLite database. Results are visually verified and the final corrected data are loaded into an Oracle database.
