A few days ago, I happened upon an
article in The Outdoor Wire which noted that the Gulf Fishery Management
Council delayed fishery management actions for scamp and yellowmouth grouper
“based on uncertainty associated with private recreational
landings estimates generated by the federal recreational data collection
program, the Marine Resource [sic] Information Program’s Fishing Effort
Survey (MRIP-FES). The Council is
hesitant to base sector allocation for the Scamp Complex (scamp and yellowmouth
grouper) on MRIP-FES estimates before its Scientific and Statistical Committee
can review the results of a pilot study being conducted to address MRIP-FES
overestimation issues.”
For those not familiar with the “overestimation issues,” in
2023, the National Marine Fisheries Service discovered that it’s Marine
Recreational Information Program was overestimating recreational fishing
effort, which in turn inflated recreational catch and landings estimates. Apparently, due to the order of questions presented
in the Fishing Effort Survey, anglers were reporting that they took more
fishing trips than they actually did, skewing the survey results.
In
response, NMFS engaged in a multi-year process to revise the Fishing Effort
Survey. That process is now at, or very
close to, completion, and revised recreational effort, catch, and landings data
should be available this spring, although the rollout might be delayed by last
year’s government shutdown. The
revised effort—and
so catch and landings—estimates are expected to be lower than those developed
prior to the survey revisions. It
appears that private-boat data will be impacted more than the data for
shore-based anglers, and that data for the periods when fewer anglers fished (expressed
in two-month “waves”) will face greater revisions than data from periods with
higher angling activity. The extent of
the revisions will also vary from state to state.
Assuming that everything is rolled out on, or at least
somewhat close to, schedule, the next question is how the new data will impact
fishery management measures, possibly including the allocation of the allowable
catch between the commercial and recreational sectors.
“For stocks assessed to date, this increase in effort from
the [Fishing Effort Survey] in historical catch estimates has generally
resulted in a retrospective increase in estimates of fish stock abundance,
especially for those fisheries with large recreational components.”
It almost certainly follows that, when stock assessments are
conducted after the downward-revised effort data becomes available—the 2027
benchmark stock assessment for striped bass comes to mind—the estimate of stock
abundance will be revised downward in response to that data.
In most fisheries, that might not have a direct
effect on recreational management measures; while the spawning stock biomass of
a given fish stock might be lower than previously believed, the recreational
removals of fish from that stock will also be lower than previously estimated. As long as both the estimate of biomass and the
estimate of recreational removals decline by about the same percentage, the
current management measures might well remain unchanged.
However, that won’t be the case in commercial fisheries,
which fish on a hard-poundage quota that is based on fish abundance. (To oversimplify the quota-setting process,
managers go through a series of steps to determine how many fish, measured in
pounds/metric tons, can be safely removed from a population each year. That becomes the annual catch limit, which is
divided between the commercial and recreational sectors based on predetermined
allocation percentages. The commercial
allocation, as modified for management uncertainty, becomes the commercial
quota.)
If the spawning stock biomass was overestimated, the
commercial quota based on that overestimate was probably too large. Some fish stocks might have been harmed as a
result. Should that prove to be the
case, and a stock is found to be significantly below its biomass target, and perhaps
even overfished, recreational management measures might be indirectly affected,
as both commercial and recreational landings are reduced in order to rebuild
that stock to its biomass target.
But it’s not only management measures—size limits, bag
limits, and seasons—that might be affected by the revised estimates of
recreational effort, catch, and landings.
Allocations between the commercial and recreational sectors might be revised
as well.
One of the stated reasons for the amendment was that
“The commercial and recreational allocations for all three
species are currently based on historical proportions of landings (for summer
flounder and black sea bass) or catch (for scup) from each sector. These allocations were set in the mid-1990s
and have not been revised since that time.
Recent changes in how catch is estimated has resulted in a discrepancy
between the current levels of estimated sector-specific catch and harvest and
these allocations.”
In response to that discrepancy,
“For all three species, the preferred alternatives would
revise the allocations using the same base years as the current allocations,
updated with recent data on catch and landings in those years. For all three species, the revised
allocations would be catch-based and there would be no phase-in period.”
Thus, the amendment shifted the summer flounder allocation
from 60% (of landings) commercial/40% recreational to 55% (of catch)
commercial/45% recreational, shifted the black sea bass allocation from 49% (of
landings) commercial/51% recreational to 45% (of catch) commercial/55%
recreational, and shifted the scup allocation from 78% (of catch)
commercial/22% recreational to 65% commercial/35% recreational, all based on
the then-new Marine Recreational Information Program data.
Summer flounder, scup, and black sea bass were not the only
species affected. For
example, also in 2022, the Gulf of Mexico Fishery Management Council revised
the red grouper allocation from 76% commercial/24% recreational to 59.3%
commercial/40.7% recreational, doing so
“Because the recreational landings estimates are greater
using the new survey than the previous estimates of recreational landings, the
commercial-recreational allocation would shift from 76 percent and 24 percent,
respectively, to 59.3% and 40.7% respectively.”
That leads to the obvious question: If the revised Fishing Effort Survey data
leads to estimates of anglers’ catch being reduced in the base
years used to calculate allocations, will the regional fishery management
councils, consistent with their actions when recreational landings were revised
upward, now revisit allocations to reflect the new understanding
of recreational removals during the designated base years?
While going through such an exercise might not seem
worthwhile for some species, where the shift might only be a percentage point
or two, in other cases, a reallocation based on lower recreational catch and harvest
might bring a real benefit to the commercial sector, particularly if the
estimate of spawning stock biomass, and so commercial quota under current
allocations, is reduced in response to the new recreational estimates. Under such circumstances, a reallocation
based on the revised numbers might keep some commercial quotas closer to the
status quo.
That doesn’t mean that reallocation will necessarily happen;
regional fishery management councils aren’t required to tie allocation to historical
landings, and are free to leave things as they are.
Thus, when I look at the article that gave rise to this
post, I have to admit that I’m a little surprised that the Gulf Council delayed
its decision on scamp and yellowmouth grouper allocation. While waiting for the Science and Statistical
Committee’s analysis was the right thing to do—fisheries decisions should
always be based on the best scientific information available—the Gulf Council,
at least in recent years, has demonstrated a definite slant toward the
recreational sector, and it’s pretty likely that delaying action on allocation
won’t benefit the recreational side at all.
So, it will be interesting to see whether the other regional
fishery management councils will revisit allocations, once the revised
recreational catch and landings data is released.
