Management Options VI

Payback & Carryover

No Payback
Before 2032, under the rebuilding plan; after 2032, based on the fishery status. The exceeded recreational catch will be deducted from the next year.
No Carryover
Carryover to the same sector, component, or state next year, but make sure the actual landing doesn't exceed 95% of the OFL.
Carryover to the same sector, component, or state next year, but make sure the actual landing doesnt exceed 50% of the difference between ABC and OFL.

Total Catch & Total SSB

The dynamics of the median total catch (upper) and the median total spawning stock biomass (SSB; lower) during the projection period.

Catch: Commercial, For-hire, Private Angling

The dynamics of the median catches for the Commercial Sector, the For-hire Component, and the Private Angling Component during the projection period.

SSB: East & West

The dynamics of the median spawning stock biomass (SSB) in the East Gulf and West Gulf during the projection period.

Commercial Catch: East & West

The dynamics of the median Commercial catches in the East Gulf and West Gulf during the projection period.

For-hire Catch: East & West

The dynamics of the median For-hire catches in the East Gulf and West Gulf during the projection period.

Private Angling Catch Catch: East & West

The dynamics of the median Private Angling catches in the East Gulf and West Gulf during the projection period.

Federal For-hire Season Length

The estimated median lengths of the fishing seasons for the Federal For-hire component and the variations during the projection period.

Note: The season length is estimated based on the quota and the average catch rate in 2018.

State Private Angling Season Length

The estimated median season lengths for the Private Angling component in each state during the projection period.

Note: The season length is estimated based on the quota and the average catch rate in 2018.

Kobe Plot

Kobe plot with median fishing mortality ratio (relative to FSPR26%) and median spawning biomass ratio (relative to SSBSPR26%). The Kobe plot is divided into four panels: The red panel (upper left) corresponds to the “overfished and overfishing phase” area. The light green panel (lower right) is the “no risk” area. The orange panel (lower left) corresponds to the “overfished, but not overfishing” area. The olive-green panel (upper right) is the “overfishing, but no overfished” area. This Kobe plot characterizes the mediate situations. Blue circles represent the annual trajectory of the Gulf of Mexico red snapper fishery over time.

Recruitment: East & West

The dynamics of the median recruitment in the East Gulf and West Gulf during the projection period.
