DEPLETED FISH STOCKS: WHEN SHOULD THE KILLING STOP?

 

A little over a week ago, my marina gave me a call, and asked when I planned to put my boat in the water.  I thought for a second, and ended up saying the 10th or 15th of April, even though I hadn’t given the launch date all that much thought; while I always look forward to getting back on the water, the simple truth is that I’m an angler, not a “boater,” and never saw too much point to setting foot on a vessel unless there was some sort of fish around.

And right now, that’s just not the case.

The fact that I’m writing on St. Patrick’s Day adds a little more poignancy to that fact.  When I first moved out to Long Island, March 17 was the unofficial start of the winter flounder season.  Party boats sailed with full loads, and private boats swarmed in bay shallows, where the sun shining through thin water warmed dark mud bottoms, and the flatfish began to stir.

Back then, New York’s anglers took millions of winter flounder home every year.  The fishing happened to peak in 1984, my first year fishing on Great South Bay, when nearly 14.5 million winter flounder were landed by the state’s recreational fishermen.  But soon after that, New York’s recreational flounder fishery began to tank.  By 1994—just ten years after the peak—recreational landings in the state’s waters had fallen by more than 95%, to about 667,000 fish, and things just kept getting worse from there.

By 2010, landings had fallen so low that samplers for theNational Marine Fisheries Service’s Marine Recreational Infoprmation Program, usedto estimate recreational effort, catch, and landings, could no longer find enough fishermen who had caught winter flounder, and so could no longer produce even marginally reliable estimates of the number of fish caught.  The point estimate for 2023 was a mere 535 fish, but there was so much uncertainty in the data that the actual number might have fallen anywhere between 0 and 1,680—at any rate, a tragically small number when compared to the millions of fish that were once yielded by a healthy flounder stock.

We see the same story repeated along the coast between Maryland and Rhode Island, the states that once hosted the same Southern New England/Mid-Atlantic winter flounder stock (the SNE/MA stock is also found off southern Massachusetts, but the way that MRIP presents recreational data, it’s impossible to separate SNE/MA landings from those properly attributable to the Gulf of Maine stock of winter flounder).  In 1984, all of those states’ anglers combined to land a little over 27 million winter flounder, while the 2023 point estimate for the combined states was 3,410, but the actual figure could probably fall anywhere between 0 and 7,685, again evidencing a tragic and pitiful decline.

Such numbers make it clear that, by any realistic measure, the Southern New England/Mid-Atlantic winter flounder stock is severely depleted, and barely even a wisp of what it once was.

Which will let you understand why I found myself dismayed when a couple of New York’s party boat captains recently began seeking an increase in landings.

New York’s recreational winter flounder regulations are fairly restrictive, although not unreasonably so given the depleted state of the stock.  Anglers may keep two fish per day, provided that such fish are at least 12 inches long, during a season that runs from April 1 though May 30;

Apparently that’s not good enough for, as described in the Bulletin of New York’s Marine Resources Advisory Council, at the Council’s January 9, 2024 meeting,

“Marc DeJung, who runs a fishing head boat out of Pt. Jefferson requests that the DEC begin to allow his customers to keep the occasional flounder that they may catch while fishing during June, July, August, and September.  It’s a by-catch fishery, so let people keep their by-catch…

“Mr. Jamie Quarisemo, Miss Montauk, NY is thinking along the same lines with just a little difference.  He would like to see something open up for flounder—offshore.  He is referring to Federal waters and not state waters and since everyone now uses GPS, there shouldn’t be a question with law enforcement as to what waters they were fishing in.  He thinks they should follow federal regulations as well.”

Listening to such comments, one begins to wonder whether there is any fish out there that these folks might not kill, or whether their mindset is such that returning a fish to the water instead of tossing it into a pail causes them real distress.

After all, the inshore party boat operator didn’t seem to be planning to sail on directed winter flounder trips.  Instead, should one of his customers happened to catch, along with the 3 black sea bass, 4 summer flounder, and 30 scup that such customer could already kill and take home, a winter flounder, the captain wanted such customer to be able to kill it, regardless of the poor health of the stock, instead of having to return it, alive, to the water.

It’s not that keeping one of the maybe half-dozen or dozen flounder the boat's customers might catch would put even a single additional dollar in the boat owner’s pockets.  It’s just that the idea of letting such fish live seems to offend the party boat captain’s values.

I have to admit that when I heard the initial request, I immediately thought of someone I know down in Galveston, Texas.  He runs a charter boat for much of the year, but also owns some commercial red snapper quota that he can use when the recreational season is closed.  In addition to his fishing operation, the same individual owns one of the largest waterfowl hunting operations in the State of Texas.  Somehow, I can’t see him going to the Fish and Wildlife folks and telling them,

“Every now and then, we get a whooping crane flying over the decoys.  I’m not planning to offer whooping crane hunts, but just in case one just happens to come flying by, my folks ought to be able to shoot it.”

No, I believe—I know—he has a lot more respect for native wildlife than that.  Maybe more respect than the folks who are looking to kill winter flounder

And no, I’m not trying to argue that flounder are scarce as whooping cranes, because that’s just not true, although it’s interesting to stop and think about the sort of thing that might, in theory, happen if someone tried to get Southern New England/Mid-Atlantic winter flounder listed under the Endangered Species Act.

It's even more interesting to think about what might happen if such a listing effort succeeded.

The Endangered Species Act defines a species as “endangered” if such species

“is in danger of extinction throughout all or a significant part of its range…’

and deems a species “threatened” if it

“is likely to become an endangered species within the foreseeable future throughout all or a significant part of its range.”

Taking that language on its face, it would seem to exclude winter flounder from either definition.  While the fish may not be as abundant as they once were, when one considers all of the flounder assigned to the Southern New England/Mid-Atlantic, Gulf of Maine, and Georges Bank stocks, there seems little real danger of the species becoming either extinct or endangered in the foreseeable future.

However, the Act defines “species” to include

“any subspecies of fish or wildlife or plants, and any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature.  [emphasis added]”

And with that definition, it is not necessarily relevant that there might be a sufficient abundance of winter flounder in parts of the Gulf of Maine, or perhaps on Georges Bank, to make extinction unlikely in the foreseeable future.  The question instead becomes whether there is a distinct population segment of flounder, perhaps somewhere in Long Island Sound, that is at severe risk.

A joint policy statement, issued by the U.S. Fish and Wildlife Service and the National Oceanographic and Atmospheric Administration on February 7, 1996 provides guidance for determining whether a “distinct population segment” exists:

“Three elements are considered in a decision regarding the status of a possible [distinct population segment] as endangered or threatened under the Act.  These are applied similarly for addition to the lists of endangered and threatened wildlife and plants, reclassification, and removal from the lists.

“1. Discreteness of the population segment in relation to the remainder of the species to which it belongs,

“2. The significance of the population segment to the species to which it belongs, and

“3. The population segment’s conservation status in relation to the Act’s standards for listing…

Discreteness:  A population segment of a vertebrate species may be considered discrete if it satisfies either one of the following conditions:

“1. It is markedly separated from other populations of the same taxon as a consequence of physical, physiological, ecological, or behavioral factors.  Quantitative measures of genetic or morphological discontinuity may provide evidence of this separation.

“2. It is delineated by international government boundaries…

“Significance:  If a population segment is considered discrete under one or more of the above conditions, its biological and ecological significance will then be considered in light of Congressional guidance…that the authority to list DPS’s be used ‘…sparingly’ while encouraging the conservation of genetic diversity.  In carrying out this examination, the Service will consider available scientific evidence of the discrete population segment’s importance to the taxon to which it belongs, but is not limited to the following:

“1. Persistence of the discrete population segment in an ecological setting unusual or unique for the taxon,

“2. Evidence that loss of the discrete population segment would result in a significant gap in the range of a taxon,

“3. Evidence that the discrete population segment represents the only surviving natural occurrence of a taxon that may be more abundant elsewhere as an introduced population outside its historic range, or

“4. Evidence that the discrete population segment differs markedly from other populations of the species in its genetic characteristics.

Status:  If a population segment is discrete and significant (i.e., it is a discrete population segment) its evaluation for endangered or threatened status will be based on the Act’s definitions of those terms and a review of the factors enumerated in section 4(a).  It may be appropriate to assign different classifications to different DPS’s of the same vertebrate taxon.”

Could there be one or more distinct population segments of winter flounder swimming somewhere within New York’s waters?

A species stock assessment produced by the State of New York in 2014 noted that

“In New York, two distinct behavioral groups have been identified: an inshore contingent that is present in coastal bays year-round, and an offshore contingent of larger individuals that travels inshore during the winter to spawn...

while at least one scientific paper, which found fairly severe inbreeding occurring in populations of flounder on Long Island, noted that

“Previous research on [Long Island] proposes the existence of multiple distinct behavioral groups with observations indicating the presence of resident and migratory individuals termed ‘bay fish” and ‘offshore fish,’ respectively.  [One researcher] estimated morphometric differences and variation in age and growth across four south shore bays of [Long Island].  It is not yet clear if these contingents are genetically differentiated…  [internal references omitted]”

Another scientific paper based on research in New York’s Shinnecock Bay noted that

“If resident winter flounder represent a separate genetic population, the seasonally more abundant dispersive population may mask a long-term decline in resident winter flounder that once supported Long Island fisheries and may eventually lead to extirpation of residents.  [emphasis added]”

Thus, there is at least the possibility that distinct population segments of winter flounder exist in New York waters, or elsewhere on the coast.

But if they exist, would any of those population segments qualify for an ESA listing?

Again, that’s impossible to know unless and until a petition is submitted to the National Marine Fisheries Service.  However, the law provides that

“The Secretary shall…determine whether any species is an endangered species or a threatened species because of any of the following factors: the present or threatened destruction, modification, or curtailment of its habitat or range; overutilization for commercial, recreational, scientific, or educational purposes; disease or predation; the inadequacy of existing regulatory mechanisms; or other natural or manmade factors affecting its continued existence. [formatting and internal numbering omitted]”

Taking a look at that list, it seems that nearly all of the listing criteria might apply to winter flounder in one way or another.  Certainly, filling in coastal marshes, dredging in estuaries and bays, and other alterations of inshore waters have impacted flounder habitat, while NMFS’ data shows that the Southern New England/Mid-Atlantic stock was overfished for many years.  Studies suggest that predation has had a major impact on the recruitment of new fish into the population.  And regulators, whether the New England Fishery Management Council or the Atlantic States Marine Fisheries Commission’s Winter Flounder Management Board have never managed to impose regulations stringent enough to allow the population to rebuild.

So, again, there is at least an arguable basis for considering a discrete population segment of winter flounder for an Endangered Species Act listing.

And if that listing ever happened, much on the coast would change, because it would then be illegal to "take any such species within the United States or the territorial waters of the United States."

And in that context, "take" doesn't just mean to toss a flounder in a pail to bring home, but to "harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct."

So dredging a channel or a boat basin where flounder might be found, or fishing for scup or sea bass or anything else that requires a bait that flounder might eat, might all be significantly restricted, or even prohibited, if they result in too many incidental flounder "takes."

It could become a significant burden, but things should never get that far.

About a decade ago, the New York State Department of Environmental Conservation, responding to an ASMFC action, proposed regulations that would have quintupled the length of the recreational winter flounder season, to something like what the party boat operators recently suggested to the Marine Resources Advisory Council.  

The public response to such proposal was overwhelmingly negative, with comments opposing the proposal coming in not only from anglers, but from national conservation groups. At least one of those groups, the Center for Biological Diversity, frequently files petitions under the Endangered Species Act, and resorts to the courts when such petitions are denied.

That didn't happen the last time winter flounder regulations were proposed, perhaps because the DEC, in the face of such opposition, wisely decided to withdraw the proposed regulatory change.

There is little doubt that, if the matter comes before the Marine Resources Advisory Council once again, the Council will vote for an expanded winter flounder fishing season, for the makeup of the Council, which is dominated by the recreational and commercial fishing industries, virtually assures that conservation concerns will ultimately be ignored.  And there is a very good chance that if the DEC decided to do what the party boat operators ask, and again propose allowing anglers to kill more winter flounder, the same sort of opposition would arise once again.

We can at least hope that will be the case.

Because, while it’s difficult to decide just when it’s time to stop exploiting a badly depleted stock, it’s easy to say that when fish get so scarce that landings fall to less than 0.004%--that’s less than four one-thousandths of one percent—of what they were in the not-so-distant past, then the time to stop killing passed a very long time ago.
