Stock Summary Description

Information Contained in the Stock Summary Documents

  • A list of all stocks present in the region
    • specifies whether the stock includes B/Bmsy, U/Umsy, B/Bmgt, and U/Umgt time series data
    • specifies whether TB or SSB is preferred, and whether ER or F is preferred, if both types are present

Information available for each stock:

  • Metadata (scientific name, area, management authority, assessor, assessment years)
  • Reference points available for stock
  • Time series available for stock
  • Plots – based on available data, may include:
    • Kobe plot (MSYpref) – Plots U/Umsy vs. B/Bmsy if available, filling in gaps with U/Umgt and B/Bmgt if available
    • Kobe plot (MGTpref) – Plots U/Umgt vs. B/Bmgt if available, filling in gaps with U/Umsy and B/Bmsy if available
    • Spawner Recruitment – Plots recruits vs. spawning-stock biomass
    • Surplus Production – Plots annual surplus production vs. total biomass
    • Total Biomass – Preferably plots the most recent TB time series from an assessment with a MSY, management target, or limit reference point available, otherwise plots most recent TB time series.
    • Spawning stock biomass – Preferably plots the most recent SSB time series from an assessment with a MSY, management target, or limit reference point available, otherwise plots most recent SSB time series.
    • Total abundance (in numbers) – Preferably plots the most recent TN time series from an assessment with a MSY, management target, or limit reference point available, otherwise plots most recent TN time series.
    • Fishing mortality (instantaneous rate) – Preferably plots the most recent F time series from an assessment with a MSY, management target, or limit reference point available, otherwise plots most recent F time series.
    • Exploitation rate (annual proportion) – Preferably plots the most recent ER time series from an assessment with a MSY, management target, or limit reference point available, otherwise plots most recent ER time series.
    • Recruits – Plots the most recent recruitment time series. If known, the year range during which recruitment deviates were estimated in the assessment model is shaded grey.
    • TC, TL, RecC – Plots most recent catch and/or landings as well as recreational catch and MSY if they are also available from that assessment. (The year range of moratoriums are shaded grey if available.)
    • TAC, Cpair, Cadv – Plots most recent total allowable catch or landings (or other measures of total quota), the corresponding catch or landings, and the corresponding scientifically advised catch if available from the same assessment.
    • survB – Plots the most recent fishery-independent survey biomass time series.
    • CPUE – Plots the most recent fishery-independent catch-per-unit-effort time series.
    • EFFORT – Plots the most recent fishing effort time series.
    • CdivMSY – Plots the ratio of the most recent catch time series to MSY. MSY is drawn from the assessment directly if available, or else is calculated from Bmsy and Umsy reference points (including proxies) if available.
