§ 648.143 Black sea bass accountability measures. ( a ) *Commercial sector fishery closure.* The Regional Administrator will monitor the harvest of commercial quota based on dealer reports, state data, and other available information. All black sea bass landed for sale in the states from North Carolina through Maine by a vessel with a moratorium permit issued under § 648.4(a)(7) shall be applied against the commercial annual coastwide quota, regardless of where the black sea bass were harvested. All black sea bass harvested north of 35°15.3′ N. lat., and landed for sale in the states from North Carolina through Maine by any vessel without a moratorium permit and fishing exclusively in state waters, will be counted against the quota by the state in which it is landed, pursuant to the FMP for the black sea bass fishery adopted by the ASMFC. The Regional Administrator will determine the date on which the annual coastwide quota will have been harvested; beginning on that date and through the end of the calendar year, the EEZ north of 35°15.3′ N. lat. will be closed to the possession of black sea bass. The Regional Administrator will publish notification in the Federal Register advising that, upon, and after, that date, no vessel may possess black sea bass in the EEZ north of 35°15.3′ N. lat. during a closure, nor may vessels issued a moratorium permit land black sea bass during the closure. Individual states will have the responsibility to close their ports to landings of black sea bass during a closure, pursuant to the FMP for the black sea bass fishery adopted by the ASMFC. ( 1 ) *Commercial ACL overage evaluation.* The commercial sector ACL will be evaluated based on a single-year examination of total catch (landings and dead discards). Both landings and dead discards will be evaluated in determining if the commercial sector ACL has been exceeded.
( 2 ) *Commercial landings overage repayment.* Landings in excess of the annual coastwide quota will be deducted from the quota allocation for the following year in the final rule that establishes the annual quota. The overage deduction will be based on landings for the current year through September 30, and landings for the previous calendar year were not included when the overage deduction was made in the final rule that established the annual coastwide quota for the current year. If the Regional Administrator determines during the fishing year that any part of an overage deduction was based on erroneous landings data that were in excess of actual landings for the period concerned, he/she will restore the overage that was deducted in error to the appropriate quota allocation. The Regional Administrator will publish notification in the Federal Register announcing the restoration.
( b ) *Non-landing accountability measure.* In the event that the commercial ACL has been exceeded and the overage has not been accommodated through the landings-based AM, then the following procedure will be followed: ( 1 ) *Overfishing, rebuilding, or unknown stock status.* If the most recent estimate of biomass is below the BMSY threshold (*i.e.,* B/BMSY is less than 0.5), the stock is under a rebuilding plan, or the biological reference points (B or BMSY) are unknown, and the commercial ACL has been exceeded, then the exact amount, in pounds, by which the most recent year's commercial catch estimate exceeded the most recent year's commercial ACL will be deducted, in the following fishing year from the commercial ACT, as a single-year adjustment.
( 2 ) *If biomass is above the threshold, but below the target, and the stock is not under rebuilding.* If the most recent estimate of biomass is above the biomass threshold (B/BMSY is greater than 0.5), but below the biomass target (B/BMSY is less than 1.0), and the stock is not under a rebuilding plan, then the following AMs will apply: ( i ) If the Commercial ACL has been exceeded, but not the overall ABC, then no single-year AM payback is required.
( ii ) If the Commercial ACL and ABC have been exceeded, then a scaled single-year adjustment to the commercial ACT will be made, in the following fishing year. The ACT will be reduced by the exact amount, in pounds, of the product of the overage, defined as the difference between the commercial catch and the commercial ACT, and the payback coefficient. The payback coefficient is the difference between the most recent estimate of biomass and BMSY (*i.e.,* BMSY−B) divided by one-half of BMSY.
( 3 ) *If biomass is above* BMSY. If the most recent estimate of biomass is above BMSY (*i.e.,* B/BMSY is greater than 1.0), then no single-year AM payback is required.
( c ) *Recreational ACL Evaluation.* The recreational sector ACL will be evaluated based on a 3-year moving average comparison of total catch (landings and dead discards). Both landings and dead discards will be evaluated in determining if the 3-year average recreational sector ACL has been exceeded.
( d ) *Recreational AMs.* If the recreational ACL is exceeded, then the following procedure will be followed: ( 1 ) *If biomass is below the threshold, the stock is under rebuilding, or biological reference points are unknown.* If the most recent estimate of biomass is below the BMSY threshold (*i.e.,* B/BMSY is less than 0.5), the stock is under a rebuilding plan, or the biological reference points (B or BMSY) are unknown, and the recreational ACL has been exceeded, then the exact amount, in pounds, by which the most recent 3-year average recreational catch estimate exceeded the most recent 3-year average recreational ACL will be deducted in the following fishing year, or as soon as possible thereafter, once catch data are available, from the recreational ACT. This payback may be evenly spread over 2 years if doing so allows for use of identical recreational management measures across the upcoming 2 years.
( 2 ) *If biomass is above the threshold, but below the target, and the stock is not under rebuilding.* If the most recent estimate of biomass is above the biomass threshold (B/BMSY is greater than 0.5), but below the biomass target (B/BMSY is less than 1.0), and the stock is not under a rebuilding plan, then the following AMs will apply: ( i ) *If the Recreational ACL has been exceeded.* If the Recreational ACL has been exceeded, then adjustments to the recreational management measures, taking into account the performance of the measures and conditions that precipitated the overage, will be made in the following fishing year, or as soon as possible thereafter, once catch data are available, as a single-year adjustment.
( ii ) *If the fishing mortality (F) has exceeded FMSY (or the proxy).* If the most recent estimate of total fishing mortality exceeds FMSY (or the proxy) then an adjustment to the recreational ACT will be made as soon as possible once catch data are available, as described in paragraph (d)(2)(ii)(A) of this section. If an estimate of total fishing mortality for the most recent complete year of catch data is not available, then a comparison of total catch relative to the ABC will be used. ( A ) *Adjustment to Recreational ACT.* If an adjustment to the following year's Recreational ACT is required, then the ACT will be reduced by the exact amount, in pounds, of the product of the overage, defined as the difference between the most recent 3-year average recreational catch and the most recent 3-year average recreational ACL, and the payback coefficient, as specified in paragraph (d)(2)(ii)(B) of this section. This payback may be evenly spread over 2 years if doing so allows for use of identical recreational management measures across the upcoming 2 years.
( B ) *Payback coefficient.* The payback coefficient is the difference between the most recent estimate of biomass and BMSY (*i.e.,* BMSY−B) divided by one-half of BMSY.
( 3 ) If biomass is above B *MSY* . If the most recent estimate of biomass is above BMSY (*i.e.,* B/BMSY is greater than 1.0), then adjustments to the recreational management measures, taking into account the performance of the measures and conditions that precipitated the overage, will be made in the following fishing year, or as soon as possible thereafter, once catch data are available, as a single-year adjustment.
( e ) *State/Federal disconnect AM.* If the total catch, allowable landings, commercial quotas, and/or RHL measures adopted by the ASMFC Summer Flounder, Scup and Black Sea Bass Management Board and the MAFMC differ for a given fishing year, administrative action will be taken as soon as possible to revisit the respective recommendations of the two groups. The intent of this action shall be to achieve alignment through consistent state and Federal measures such that no differential effects occur to Federal permit holders.
