In recent years, “great” fish counts have become all the
rage, particularly in the southeast, where the fishing tackle industry, boating
industry, and anglers’ rights groups have been trying to use them as a way to challenge
the peer-reviewed stock assessments and increase recreational landings.
The
so-called “Great Red Snapper Count,” which was completed a few years ago, was
the first such effort, but they all follow the same basic pattern. First, the industry groups
donate enough money to their local congressmen to get their attention. Then, they
convince one or two of those congressmen—and, depending on how big the
contributions were, it might not take much convincing—to attach a rider to an
appropriations bill, which will provide funding for a comprehensive study of
the species in question, performed by academic researchers, that the industry
believes will discredit the federal stock assessments and prove that federal
fisheries regulations are too restrictive.
The resulting federal appropriation is typically large
enough to fund a team of very competent scientists, and provide them with the support
they need to conduct an intensive count of whatever the target species is, perhaps
even letting them look for fish in places where no one has ever looked before.
Given the intensity of the search, there is a very good
chance that more fish are going to be found.
When more fish are found, the industry then argues that
there should be a one-to-one correspondence between population size and
recreational landings, and insists that recreational regulations be relaxed.
But things aren’t that cut-and-dried.
The pioneering Great Red Snapper Count provides a perfect
example of that.
“The difference noted above was driven primarily by the Great
Red Snapper Count team’s ability to survey large portions of the U.S. Gulf of
Mexico not surveyed by NOAA given limited resources. These regions are known as unclassified
bottom and consist of vast expanses of sand and mud, along with features like
extensive, partially buried oil and gas pipelines that hadn’t been studied by
fisheries scientists. When the Great Red
Snapper Count team tallied the red snapper residing over unclassified bottom,
they learned that these areas actually contain a massive ‘cryptic biomass’ of
red snapper estimated at 68 million fish!
This was most apparent in the Florida region, where unclassified bottom
supports about 31 million, or nearly two-thirds, of the region’s 48 million red
snapper.”
Yet that simple finding didn’t mean that landings could
automatically be tripled, nor did it mean that previous estimates of red
snapper abundance were categorically wrong.
As
the National Marine Fisheries Service observed,
“The abundance estimates for high relief natural and
artificial structures, where most fishing occurs, are similar to that of the
2018 assessment.
“The Great Red Snapper count confirmed previous
estimates of the biomass on the habitats associated with the fishery, high
relief areas such as reefs and ledges. This
previously unknown biomass associated with low relief, sand and mud bottom
habitat is a welcome revelation of this research. The discovery of additional biomass is good
news which may help ease some management restrictions. [emphasis added]”
Thus, the previous federal red snapper surveys were accurate
as far as they went, but NMFS simply lacked the resources to search every nook
and cranny of the Gulf of Mexico just in case red snapper happened to be
there. So they looked at the places
where people fished, and got a fairly accurate count of the snapper that lived
there. But they missed the greater
biomass of fish that lived where no one had previously looked, and few people
ever fished.
Still, concentrating survey efforts in places where people
fish might make some sort of sense, for the same article in Gulf Coast
Fisherman also informs us that
“One of the four main methods used during the Great Red Snapper
Count was a Gulf-wide high-reward tagging study. Doing this study, scientists tagged and
released thousands of red snapper across the U.S. Gulf of Mexico at artificial
reefs and natural habitats and relied on fishermen to report the capture of
tagged fish. The results of the tagging
study was surprising—approximately 30% of tagged red snapper were
recaptured! To put this quantity into
context, scientists consider a recapture rate of 10% to be excellent, and
anything higher is very unusual. The 30%
tag return rate signifies impressive fishermen involvement in the Great Red Snapper
Count, but it also illustrates high fishing effort for red snapper at
artificial and natural habitats.
[emphasis added]”
That immediately raises the question of whether the 68
million red snapper that the Great Red Snapper Count found on unclassified
structure are even relevant to the recreational fishery, or to recreational
fishery management. After all, if anglers
are only interacting with the fish on high-profile structure, and the fish on unclassified
structure don’t move onto the ledges and reefs—and we have no idea whether they
do or not—it is only the fish on the high-profile structure that need to be
managed.
It’s far too early to make that decision right now. But the fact that most of the fish in the
eastern Gulf off Florida were found on unclassified structure—meaning that the
local population there is far larger than previously believed—yet Florida
charter boat captains have already started complaining that red snapper size
and abundance have been steadily declining even under current regulations, suggests
that the fish living on open bottom might not be having too much of an impact
on the recreational red snapper fishery.
The Gulf Coast Fisherman summed up the situation very
well.
“The Great Red Snapper Count results reveal that there may be
roughly three times more red snapper in the U.S. Gulf of Mexico than we once
thought. This is great news! Moreover, the impressive number of red
snapper residing over unclassified bottom represents an important
discovery. It’s possible that
these fish may help to replenish the reef aggregations so that those areas of
natural and artificial structure can continue to sustain high levels of
harvest. Future studies will likely
investigate the ecological roles of the red snapper inhabiting unclassified
bottom, as well as their specific contributions to the Gulf of Mexico red
snapper stock.
“The findings from this project may
fundamentally change the way the Gulf of Mexico red snapper stock is assessed by
federal and state officials…The results of the Great Red Snapper Count are
clearly impressive, but exactly how these results will impact commercial
and recreational fishermen is less apparent. In particular, it’s unlikely that
quotas or bag limits will be tripled.
Since Gulf of Mexico red snapper are still under a rebuilding plan, and
harvest from natural and artificial habitats is very high as confirmed by the
Great Red Snapper Count team, more red snapper doesn’t necessarily mean
more harvest. One thing is for
certain: fisheries managers
responsible for making decisions about Gulf of Mexico red snapper will move
forward cautiously to ensure that the results of decades of diligent
rebuilding are preserved. [emphasis
added]”
That’s just what happened.
“Results of the Great Red Snapper Count and [an] interim
analysis are expected to be reviewed by independent experts. The Gulf of Mexico Fishery Management Council’s
Scientific and Statistical Committee will also review the results…We will
continue to work with our partners on the Gulf of Mexico Fishery Management
Council and its Scientific and Statistical Committee to peer-review the
assessment and adjust red snapper management as appropriate.”
“The overall conclusion of the group was that the presented
stock assessment model was not suitable to proceed to an Operational Assessment
and that instead a Benchmark Assessment and another full review should be
conducted.”
While all of the criticism did not revolve around Great Red
Snapper Count data, with much addressing how the Gulf should be divided up into
separate areas, how to incorporate the Great Red Snapper Count data was also an
issue, with the meeting summary saying
“the SSC thought it prudent to create a topical working group
to explore how to better include information gathered from the [Great Red
Snapper Count] in the stock assessment process.
The SSC recommended that some of the principal investigators, or other
available contributors from the GRSC could participate in the workgroup. The results of these deliberations would be
made available, so that documentation of how or when GRSC data is integrated
could be reported out.”
“it would have been reasonable to expect the results of the
GRSC simply become the new benchmark.
NOAA insisted that those findings would have to be calibrated and
synched up with the data streams and techniques it had used in the past. The same data streams and techniques that the
GRSC had shown to be inaccurate by a factor of at least three.”
Of course, the last sentence of that quote wasn’t quite
true, as the Great Red Snapper Count confirmed the accuracy of
federal mangers’ estimates of red snapper populations on high-profile
structure; NMFS may never have looked on the unclassified bottom because it lacked
the resources to do so, but that has little or nothing to do with the accuracy
of its data or techniques.
But the CCA just needed to throw a tantrum, when it didn’t
get the result that it had been more-or-less guaranteeing its members since
sometime around 2017.
For them, the Great Red Snapper Count wasn’t really “great”
at all, even though it did significantly expand or knowledge about red snapper
distribution in the Gulf of Mexico.
Still, that didn’t stop the CCA and fellow travelers from
working to spend more taxpayer dollars trying to expand the “great fish count”
approach to other species and other places.
Their next approach was a simple riff on the first, the
so-called “Great South Atlantic Red Snapper Count.” It followed the established format, in which
friendly lawmakers had Congress appropriate cash for a study of red snapper
abundance, that would hopefully (from the industry/anglers’ rights standpoint)
prove that there were more fish around than NMFS believed.
As
described by the ever-reactionary Blair Wickstrom, in the pages of Florida
Sportsman,
“As it stands today, the current stock assessment, which
indicates we’re overfishing red snapper, is set in stone until 2028. However, we have hope that the independent
30-month study dubbed the Great South Atlantic Red Snapper Count will provide
much-needed clarity on the true stock assessment.”
It’s just not clear what Wickstrom, and the rest of the
industry/anglers’ rights cabal, expect the “true” stock assessment to say, and
how they expect it to help them.
Nobody disagrees that the South Atlantic red snapper stock
is responding well to management measures.
Although the
stock was badly overfished as recently as 2010, when spawning stock biomass was
only 9% of the target level and the fishing mortality rate was more than four
times the fishing mortality target, things have improved since then. In June 2005, NMFS
found that the stock was neither overfished nor experiencing overfishing.
So, red snapper abundance, per se, isn’t really the
problem.
Yes, a bigger estimate of spawning stock biomass might lead
to a somewhat larger annual catch limit, but
the recreational sector already enjoys a reasonably high annual catch limit right
now. In 2025, the annual catch limit
amounted to 509,000 red snapper, which should have been enough to keep most
recreational fishermen happy, even if the commercial sector gets to land about
28% of the fish.
A low annual catch limit isn’t the problem.
The recreational and commercial fishermen are forced to
share only the remaining 34,000 red snapper that don’t get fed to the sharks
and the crabs.
In doing so, they also find themselves firmly impaled on the
horns of a dilemma. On one hand, they
want to argue that the ocean is filled with red snapper, so that they can enjoy
longer seasons and perhaps a bigger bag.
But on the other hand, they can’t admit that high red snapper abundance
means that anglers can’t avoid catching—and inadvertently killing—loads of red
snapper during the closed season, in numbers high enough to justify setting
more than 90% of the annual catch limit aside to cover dead recreational
discards.
They’re caught in a lose/lose situation, one that the Great
South Atlantic Red Snapper Count won’t be very great at resolving, even if and
when it is incorporated into the next stock assessment. A count is the wrong tool for the problem at
hand.
Once again, we’re looking at a situation where a coalition
of industry and anglers’ rights groups prevailed on local congressmen—those political
action committees are certainly useful things—to allocate $10 million to study the
abundance of greater amberjack in the waters stretching from North Carolina to
the Rio Grande.
“it is a completely different story in the Gulf of [Mexico]. Currently, no greater amberjack season has
been set for 2026, and the previous seasons were set so that anglers would have
something to catch when for-hire (charters) red snapper season is closed. The [Alabama Deep Sea Fishing Rodeo], which
is held on the third full weekend of July each year, hasn’t had an amberjack
category in more than 15 years.”
“The overall and regional estimates…were within the scale of
the most recent stock assessments of Greater Amberjack. For the South Atlantic, the estimate derived
from underwater cameras was 3.08 million with a percent coefficient of
variation [a measure of uncertainty]…of 35%.
The estimate derived from using acoustics was similar, 3.09 million,
with a higher CV of 41.5 %. For scale of
comparison, the terminal year (2018) of the latest South Atlantic Greater
Amberjack Stock Assessment was 2.64 million.
While a CV around the stock assessment estimate is not reported, annual
estimates over the past 20 years of the stock assessment (1999-2018) ranged
from 1.7 to 3.9 million age 1+ Greater Amberjack.”
So, the study does not conflict with the findings of the
last stock assessment, with respect to amberjack in the South Atlantic.
When it comes to amberjack in the Gulf of Mexico, the
Executive Summary informs us that
“Our point-estimate for the camera-only Gulf of [Mexico] population
size is higher than that from the terminal year (2018) of the latest Gulf of
[Mexico] Greater Amberjack Stock Assessment (4.34 million in our study vs. 1.39
million from SEDAR 39). However, the CV
from the camera-only estimate is quite large, at 46.4%...For comparison the
last 20-year range for SEDAR 59 is 1.39 to 3.50 million…The acoustic estimate
derived by this study for the Gulf of [Mexico] region was 1.45 million with a
CV of 21%.
The [principal investigators] recommend the video-based
methodology for any comparisons. Among
the reasons for this choice is that the length frequency distributions can be
derived. These length frequencies
indicated differences in size composition between the three major areas (W. Gulf,
E. Gulf, and SA).”
The Executive Summary also included a warning.
“The [principal investigators] also express caution
with any direct comparisons of our results to the stock assessment results. We list the range of population size
estimates derived from the stock assessment purely to inform the reader of the
scale of our estimates compared to past management assumptions. While there is some overlap—for example,
camera-based fishery independent surveys are used in the stock assessment and
used in our estimation—the methodology used in the stock assessment is
fundamentally different than adopted in our study. Further, our study is intended to be a point estimate
in time (2023) and successful management requires estimating rates of
exploitation on an annual basis… [emphasis
added]”
Predictably, the angling press failed to heed that warning,
and began blasting out reader—and advertiser—pleasing headlines such as
“Study
Finds Twice as Many Amberjack Than The Federal Authorities Reported,”
and
“Great
Amberjack Count Estimates Far More AJs in the Gulf,”
which suggest that the results of the Great Amberjack Count
and the Gulf of Mexico stock assessment are directly comparable,
when the report makes it very clear that is not the case.
Hopefully, the data that the Count developed will not be
rushed into the stock assessment as a result of that sort of hype. Hopefully, it will instead be given all necessary
consideration so that, like the data from the Great Red Snapper Count, it is only
included into the stock assessments after thorough and appropriate scientific
review.
The Great Amberjack Count, like the other counts described
earlier, was certainly a good thing, because it finally gave top fisheries
scientists enough funding to do meaningful and needed research into an
economically and recreationally important, and heavily exploited, species. That, in itself, is a sort of greatness.
But it and the other studies can only truly be great if they
expand our understanding of, and improve the sustainability of, marine fish
stocks.
Just putting more dead fish in anglers’ coolers doesn’t make
them great at all.
