It’s looking ever more likely that what once seemed like a
modest yet meaningful win—the Atlantic States Marine Fisheries Commission’s
vote to reduce striped bass harvest last October—was even more modest than it
first appeared.
ASMFC’s Striped Bass Management Board seemed to be acceding to
public demands that landings be cut and a 1-fish bag limit be adopted. However, it is now clear that at least some
of those who voted that way were merely blowing smoke in the public’s
face. Now that the smoke has cleared a
bit, they are ignoring the overwhelming public sentiment for a single-fish bag,
and seeking ways to let folks kill additional fish, at least when those folks
are fishing from for-hire vessels.
I
discussed the matter at length in a recent post, and don’t intend to rehash
it all here.
It’s now time to start thinking of the next steps in the
dance—where we go and what we do when Addendum
IV to Amendment 6 of the Interstate Fishery Management Plan for Atlantic
Striped Bass proves to be another failed state management effort, and we
have to step in again to try to recover the striped bass population.
I know that a lot of folks are thinking about just throwing
up their hands and leaving the fight.
After all, if the big angler turnout and overwhelming call for a 1-fish
bag didn’t move mountains this time, why is there any hope that the next time
will be any better?
I know that feeling pretty well.
After being involved in the fishery management process for a
few decades, I know what it feels like to lose.
But, first of all, remember that anglers didn’t lose this round at ASMFC. Its Striped Bass Management Board did what
we wanted. It’s the states’ management
systems that are letting us down.
We are looking at new fishing mortality reference points
that, in the long term, should do the bass good.
We defeated the Chesapeake Bay jurisdictions’ efforts to
draw out the harvest cut over three years.
A lot of the Management Board members were and still are concerned
with the integrity of the management plan and the management process.
And if our greatest worry does come to pass, and the striped
bass stock fails to recover, we still have a good leg to stand on.
Right now, we need to be looking at Amendment
6 to the Interstate Fishery Management Plan for Atlantic Striped Bass,
and more particularly, at Management Trigger 2, which reads
“If the Management Board determines that the biomass has
fallen below the threshold in any given year, the board must adjust the striped
bass management program to rebuild the biomass to the target level within [ten
years].”
Because it is very likely that trigger will be tripped in a
very few years.
Let’s start with a simple truth.
The biomass is
probably below the threshold right now.
That’s a sobering thought, but the Draft
Addendum IV to Amendment 6 to the Fishery Management Plan for Atlantic
Striped Bass included a chart (on page 11) which projected that the biomass
would fall below threshold—that the stock would be technically overfished—this year.
As for next year, the Update
of the Striped Bass Stock Assessment using Final 2012 Data noted that
“If the current fully-recruited [fishing mortality] (0.200)
is maintained during 2013-2017, the probability of being below the [spawning
stock biomass] reference point increases to 0.86 by 2015. After 2016, the probability is expected to
decline slightly…If the
fully-recruited [fishing mortality] decreases to the current Ftarget
(0.180) and is maintained during 2013-2017, the probability of being below the
[spawning stock biomass] reference point reaches 0.77 by 2015 and declines
thereafter… [emphasis added]”
Based on that finding, the striped bass is already behind
the eight ball.
Regulations in place during 2012 will not change until 2015;
although we don’t have fishing mortality rates for 2013 and 2014, there is no
reason to assume that, absent regulatory changes, those rates will be at least
equal to the F=0.200 of 2012.
In practice, fishing mortality was almost certainly higher
in 2013 than it was in 2012; total
landings in 2012 were estimated at a little over 19,500,000 pounds, while
in 2013, that estimate jumped to more than 24,300,000. Taking a more fish from a decreasing biomass
will inevitably cause the fishing mortality rate to spike.
We don’t have final figures for 2014 yet, but preliminary
numbers show even more reason to be concerned.
In the first eight months of 2012, anglers landed about 14,000,000
pounds of striped bass. That number jumped
to over 17,000,000 pounds in the first eight years of 2013, and increased again
to nearly 18,500,000 in the first eight months of 2014.
The greater part of the 2014 increase can be attributed to a
big kill of the immature and barely legal 2011 year class down in Chesapeake
Bay, but it’s still bad news, and very possibly takes us to the third scenario
envisioned in the Update,
“If the current fully-recruited [fishing mortality] increases
to Fthreshold (0.219) and is maintained during 2013-2017, the
probability of being below the [spawning stock biomass reference point reaches
0.93 by 2015 and declines thereafter.”
So given the trends in 2013 and 2014, there is an
overwhelming likelihood that the stock will be overfished—below the spawning
stock biomass threshold—next year.
Then, the only thing that needs to happen is for ASMFC to
formally determine that there is a problem.
That may not happen right away.
Complete, benchmark striped bass stock assessments take
place every five years. Thus, we won’t
see another one until late 2018, based on 2017 data. That gives Addendum IV a long time to fail and adversely affect striped bass
numbers.
However, ASMFC’s Striped Bass Technical Committee has historically conducted interim “turn-crank” assessments in nearly every year. Such assessments are far less formal and detailed than the
benchmark, and merely plug annual harvest data into the model from
the benchmark assessment, in order to update the results.
ASMFC’s striped bass
website page shows some sort of assessment, benchmark or interim, for the
years 2000-2005, 2008, 2009, 2011 and 2013.
However, due to a demand that the Technical Committee produce biological
reference points unique to Chesapeake Bay, there will probably not be
sufficient manpower available to do one in 2015.
Thus, we should begin petitioning our ASMFC
representatives and demanding that an interim, “turn-crank” assessment be done
in 2016.
We won’t be asking for great
detail, just an estimate of the size of the spawning stock biomass (although an
estimate of 2015 fishing mortality, with the new regulations in place, would
also be useful).
And if the Technical Committee determines that the spawning
stock biomass has dropped below threshold, and that Management Trigger 2 has
tripped, we must insist that managers put in place a rebuilding plan that will
restore the spawning stock to target levels within ten years.
Such a rebuilding plan will not allow the maneuvering and
loopholes that we see today.
Because in order to have mature, spawning fish in the
biomass, you have to have small fish first, and they’ve been lacking lately. The average for the Maryland
young-of-the-year index over the past 10 years was 10.4, below the
long-term average of 11.7.
Management
measures sufficient to restore the striped bass stock to target levels, and not
merely prevent current overfishing, will probably have to be a lot stronger
than what we’re seeing today.
The question, of course, is whether the states and ASMFC’s
state-based management system is up to the task of putting such measures in
place.
As we come to the end of the Addendum IV process, we already see it failing the resource and the
public, as the politically-connected for-hire fleet in New Jersey, Rhode Island
and elsewhere seeks to undo, at the state level, conservation gains won by the public
at ASMFC.
At the state level, there is nothing like the federal Magnuson-Stevens Fishery
Conservation and Management Act to assure that overfishing is really
prevented, or overfished stocks timely rebuilt.
In the end, there is only us, anglers with a burning desire
to preserve and restore the fish that we seek, and to hand them down as our
legacy to the next generations.
That will have to be enough.
And if we only hold firm, and don’t lose our faith, it can
be.
