A week or two ago, a friend of mine had a striped bass
stolen by a seal.
Even down here on Long Island, that’s not too unusual, for harbor seals have become pretty numerous during the winter, and seem to
be sticking around a little later each spring, while showing up a bit sooner each
fall.
A lot of fishermen, particularly surfcasters, aren’t very
happy to see the seals arrive, and get upset when one of them steals a
bass. That’s particularly true up on
Cape Cod, where the numbers of gray seals—animals far larger than the harbor
seals that we see on Long Island—have become extremely abundant, and make it
difficult to land a hooked fish.
My friend runs a charter boat, and so it’s important that
his customers can bring fish to the boat.
Even so, when
the seal stole his striper, he wasn’t upset, and noted that “I thought it
was kinda cool…”
And when you stop to think about things a bit, it was.
For many years, seals were scarce in Long Island
waters. When I was a boy, growing up on
western Long Island Sound (admittedly, on the Connecticut side, not on Long
Island proper, although the waters were effectively the same), seals were
seldom seen. Every couple of years, an
angler trying to catch winter flounder early in the spring would spot one, and
when that happened, the story was front-page news in the local paper.
Today, seals are regular seasonal visitors to Long Island’s
waters, and appear in the sound on a regular basis. And they are only one of a number of animals
that have become more common in recent years.
Bottlenose dolphin, absent from western Long Island Sound
for at least half a century, have returned to those waters.
And
for the past couple of seasons, humpback whales have also appeared,
something that had never happened before at any point during my lifetime.
On the South Shore of Long Island, humpback whales, along
with some fin whales and minkes, have been present right off the beaches for
most of the summer. As I write this, one humpback has entered the shallows of Moriches Bay, where it remains at a substantial
risk for stranding in the bay’s skinny water.
Farther west, another
humpback has passed through New York harbor, and was seen feeding in the area
around the George Washington Bridge.
And it’s not just marine mammals.
Osprey, which were seldom seem four or five decades ago, have become common. The fish-eating
birds seem to be nesting everywhere, from their traditional locations in
waterside trees to dedicated nest platforms, utility poles, channel markers and
even the signs on abandoned fuel docks.
And more and more often, anglers and other coastal habitués have seen bald
eagles return to the shoreline, to feed on an abundance of baitfish that can
now be found in Long Island’s bays and other protected waters.
Sharks have also become ever more abundant in Long Island’s coastal sea. In recent years, fishermen have caught thresher sharks, some
in the 500 pound range, within sight of Long Island’s beaches. This fall, I’ve heard stories of
thresher sharks slashing though schools of bait and churning up the surface inside Great South Bay.
In addition, scientists have confirmed that eastern
Long Island waters are a nursery area for white sharks, perhaps the first
such nursery ever discovered.
That sort of abundance doesn’t occur in a vacuum. Long Island’s waters are seeing an increase
in marine predators because they host so many of the forage fish that such
predators need to survive.
Such forage can take many forms, ranging from vast shoals of
sand eels that attract fish, whales and various sea birds well out in the ocean
to schools of menhaden that provide food for striped bass, bluefish, birds and marine mammals within sight of Long Island’s shores, including
in Long Island Sound.
To construct a building that lasts, builders must first
build a solid foundation. An enduring
ocean food web also rests on a solid foundation, one made up of all of the
various forage fish needed to support larger predators.
The good news is that fishery managers are taking steps to
assure that a good forage base exists.
Earlier this year, the Mid-Atlantic Fishery
Management Council adopted an omnibus amendment that would prevent the
creation of new fisheries for forage species, or allow the expansion of
existing fisheries, until such time as managers could determine with reasonable
certainty that such new fisheries would not harm predator species that depend
on such forage.
The
Atlantic States Marine Fisheries Commission has already taken action to reduce
the harvest of Atlantic menhaden, and the resulting increase in menhaden
abundance has brought an influx of predators to Long Island’s coast. Now, ASMFC
is going a step farther, and considering the abundance of ecological reference
points which would manage menhaden based on its role as a forage fish, rather
than merely tying harvest to the concept of maximum sustainable yield. Such ecological reference points, if adopted,
would be setting a very important precedent, and make it likely that the
number of big predators in local waters will not decrease.
The seals that steal fish from anglers lines, the juvenile
white sharks that feed within sight of exclusive Hamptons beaches and the
humpback whales that rise up out of the sea, water and menhaden streaming from
their not-quite-closed jaws, are all coming back to Long Island because, for the
first time in a great many years, there are enough forage fish in local waters
to support them.
Our waters are being made whole again.
As someone wrote in response to my friend’s report that he
lost a bass to a seal, “The neighborhood is totally changing.”
There’s no doubt that is true.
And that is a very good thing.
