Utilize commercial landings data by island (PR, STX, and STT) for 1994-2002 (queen conch – STX and PR only) and 1994-2006 (snapper unit 1, grouper unit 4, parrotfishes). SSC Recommendation: Accepts utilizing commercial landings data by island with years indicated above.

Silk snapper (Lutjanus vivanus)
Red grouper (Epinephelus morio) – St. Thomas USVI
Nassau grouper (Epinephelus striatus)
SSC Recommendation: Have SEFSC explore partitioning STT/STJ and STX landings using island specific TIP weight data and the appropriate years to be included. Passed by consensus.
Determine if the MSY value in the original Conch FMP is still valid, and based on the best available science. This would allow for the development of a fishery in St. Thomas.
Do not accept the MSY estimate in the Conch FMP and request additional analyses for MSY of queen conch off St. Thomas. Passed by consensus.
SSC recommended that additional data that should be included in analysis:
Queen conch (Strombus gigas)
SSC Recommendation 1: Accept OFL for STT/STJ and PR. Look at trends in size for St. Croix to assess the validity of landings data for calculating MSY. Passed by consensus.
SSC Recommendation 2: ABC for midnight, blue, and rainbow parrotfishes be set at zero and create two parrotfish units because of dramatically different life histories. Passed by consensus
Blue parrotfish (Scarus coeruleus)
Rainbow parrotfish (Scarus guacamaia)
Midnight parrotfish (Scarus coelestinus)
SSC Recommendation: Defer consideration of the STFA’s proposal to allocate ACLs by geartypes until after a process is established for setting limits and targets by species/units and then relook at this approach in relation to the calculated limits. Approved by consensus.
Fmsy Bmsy MSY
At risk 1.5 0.75 0.88*catch
Undetermined 1.0 1.0 1.0*catch
Not at risk 0.75 1.25 1.067*catch
Very at risk # 4.0 0.25 1.0
#Formula does not work in this case
SSC Recommendation: Abandon SFA formula for adjusting MSY
Adjust MSY using the following equation:
status scaler X avg. catch X vulnerability
At risk < 1
Undetermined = 1.0
Not at risk > 1
Susceptibility factors and productivity factors are being considered by the current Vulnerability Evaluation Working Group. Vulnerability incorporates susceptibility and productivity factors.
Passed by consensus
SSC Recommendation: In absence of species specific information to the contrary, OFL shall be set equal to MSY. Approved by consensus.
Set ABC based on either the 25%, 50%, or 75% lower confidence limit (LCL) of average catch, as adjusted for stock status.ABC = MSY - (avg. catch - LCL)
SSC Recommendation: Accept the above formula, but request further guidance on grounds for applying different percent confidence limits. Approved by consensus
Council would set ACL equal to or less than the ABC.
Set ACT = 0.75*MSY (=OY).
The SSC should reconsider how to set the ACT.
