SOUTHWEST
HARBOR — Adaptability is a necessary quality for any fisherman who has worked
the Gulf
of Maine the past 20 years.
Fish stocks have
ebbed and flowed like the extreme tides of the
Bay of Fundy, fisheries
regulations and requirements have swirled around
like an obscuring fog over the often-dwindling
fish populations, and litigation has raised the
stakes and muddied the regulatory waters.
So much takes
place in legislatures and hearing rooms that
it’s easy to lose sight of the fact that out on
the water fishermen are still working however
they can. In the case of the crew of
Portland-based dragger Robert Michael, that
means fishing for numbers along the Maine coast
for nearly four months out of the year.
The 54-foot
Fiberglass dragger has become the primary vessel
responsible for carrying out the semi-annual
inshore trawl survey for the states of Maine and
New Hampshire.
Getting under
way from Southwest
Harbor at first light Nov. 4, Captain Curt Rice and crewmen Dale Doucette and
Jerry Balzano were well into the fifth year of
the trawl survey, which provides data for
fisheries researchers and managers struggling to
make sense of coastal fish stocks.
Maine Department
of Marine Resources scientists Sally Sherman and
Keri Stepanek explained that the data from the
five-year effort is being used now to help in
broad assessments of herring, monkfish, shrimp,
shad and lobster, to name a few. Sherman said
federal fisheries researchers primarily use the
trawl survey data to “ground truth” stock
assessments they have made based on catch data.
But last week
Sherman’s chief concern was not how scientists
would use the data. Perched at a table in the
wheelhouse, she and Rice were engaged in a
fisherman’s discussion about weather. The day
before had been windy. The crew had gone up Blue
Hill Bay to try and get tows in
on some of the randomly preselected sites the
survey targets.
“We got one tow
in before it started to blow 50,” Rice said.
Then they’d called it quits and headed back into
Southwest
Harbor by mid-afternoon.
Thursday dawned
relatively calm with a light northerly wind
building. On the trip out the Eastern Way, Rice
chatted on the radio with the captain of Jocka,
another southern
Maine dragger.
On the way out,
crew and scientists almost instinctively
performed the few tasks required to prepare for
the day. Sherman double-checked the day’s tows
on a laptop. Stepanek hunkered a couple of exact
stainless weights out of their boxes and onto
the work deck to calibrate the digital scales
used to weigh the fish brought aboard in the
drag. Doucette and Balzano, coffee in hand,
reviewed the drag gear and put together some
food in the galley.
By 8 a.m. the
dragger had reached the first designated drag
area. As Rice ran down the area before setting
the trawl, he encountered a number of lobster
trap buoys. He called Marine Patrol to come out
and move some lobster gear out of the way. By
then, a crowd of lobster boats was working its
way out from Frenchman
Bay, tending traps on the way.
For the most
part, helpful advice came over the radio.
Lobstermen asked just what direction he would
drag in, and told him what length of gear was
attached to different colored buoys. They even
offered to come move some.
Relations with
lobstermen haven’t always been the best. In
years past, there were instances when boats
surrounded the dragger, preventing it from
setting the trawl. Now, there’s a resigned
acceptance that the survey is going on without
doing immense damage to the lobster stocks in
the area. The dragger’s presence seems to be
more of a logistical nuisance than anything,
especially during the unpredictable season
lobstermen have had this year.
The boats kept
their distance, but one came tight across the
stern checking for any lobster gear when the
drag was hauled aboard after a 20-minute tow.
There was nothing but fish.
Before the trawl
was set, Balzano pointed out the Sonar
attachments on various parts of the gear. When
the net is set, a sensor towed beside the boat
relays the positions of the attachments to a
computer on board. That way the consistent set
of the trawl can be monitored from the
wheelhouse and snags on the bottom quickly
detected.
Even in the
relatively placid conditions last week, the
dangers inherent in dragging were obvious. The
heavy steel trawl doors clanked and slammed
against the hull, chains rattled, and steel
cables crackled and whirred as they raced off
the drums.
With the heavy
gear underwater, everything came taught and,
with exception of the straining diesel,
relatively quiet for the 20-minute tow. Rice
watched the clock and the surface for lobster
gear.
“Six more
minutes and we’re legal,” he said nearing the
end of the tow.
Stepanek watched
the laptop with the net-monitoring software and
Balzano looked at the fish finder.
“Fish,” he said,
pointing to a smudge on the screen and noting
that they were above the net.
Hauling in a
trawl, even after a scant 20-minute tow, is
exciting. Balzano and Doucette shook down the
stray fish still in the mouth of the net, as it
came aboard. With the full end hoisted over the
sorting table, Balzano opened the bottom. Red
and brown lobsters, green-eyed dogfish, bright
silver herring and alewives, flat dabs, round
butter fish, haddock, squid, spiny sculpin,
translucent shrimp and whiting all spilled out
into the sunshine, squirming and flapping.
Sherman and
Stepanek set on the table immediately measuring
and sorting the lobster first. They muttered
size, sex and condition into small recorders
taped to their suspenders. Rice said the
lobsters are returned to the water as close to
the end of the drag as possible. He doesn’t
throttle the boat up to move until they are back
in the water. But that can take a while, given
the amount of lobster that comes up in some
drags now. In a couple of last Thursday’s tows,
the removal of lobster seemed to reduce the pile
of fish to be sorted by nearly half.
With lobsters
back in the water, other fish were sorted into a
series of plastic buckets and baskets. Each was
weighed. Then Doucette and Balzano got out the
measuring boards and called out the length of
each fish. Sherman and Stepanek recorded the
figures on data sheets before the fish were
tossed over the side where seagulls wait.
Meanwhile, Rice
had throttled up and set out for the next
designated site.
The fish sorting
was usually complete inside of an hour and
Balzano washed down the table and deck for the
next drag.
On Thursday, the
boat got in three tows. A fourth site was choked
with lobster gear.
“If it’s going
to take them forever, we don’t ask them to move
it,” Rice said, explaining the limits of the
Marine Patrol’s gear moving assistance. He and
Sherman consulted and headed on to the next
site.
For Rice, the
trawl survey is a break from the grind of
offshore dragging as a commercial fisherman, but
it’s far from a vacation. Outside, there’s no
gear to worry about and no designated drag
sites. On survey duty, he’s got to get used to
unfamiliar harbors and coastlines and make very
precise drags in often tight quarters.
For the
scientists, the trawl survey is time out of the
office and in touch with the fishermen and the
fish their department works to manage. Sherman
said the data from the survey keep her busy
through the year, as more requests come in for
species-specific information from fisheries
managers and researchers.
The fall survey,
working its way Downeast, will wrap up this
week. Rice and his crew will head back offshore
in the commercial fishery until Sherman and
Sepanek come aboard to do it all over again for
the 2005 spring survey. |
