Creating a home for marine life
Odd-looking objects form artificial reef in off Salter's Point
Slowly, gingerly, the huge 35-ton hydraulic crane aboard a Linberg Marine Inc.
barge lifted one of the weird-looking, sawed-off-whiffle ball-like contraptions
off the deck and gently set it down in waters off Salters Point yesterday.
It was being lowered 30 feet to the sea bottom, where it will become part of an
artificial reef designed to make fish feel right at home.
"We've got the first 20 reef balls in and we're setting up for the pallets now,"
said Larry Beggs, a representative of Reef Innovations and Diving Specialists
Inc. of Florida and the Reef Ball Development Group Inc. of Georgia, which
molded about 80 reef units earlier this month at the Fairhaven shipyard.
"Finally," said Paul Diodati, sports fisheries program manager with the State
Division of Marine Fisheries, who has been waiting nearly two years for the
effort to enhance fish stocks to get off the ground.
"It's a great site," he added. "A perfect site."
Linberg Marine is deploying the 1½-ton reef balls and the smaller, 1,300 to
1,5000 pound pallet balls to create an artificial habitat at the bottom of a
3.5-acre site off Salters Point. The company deployed about 45 of the units
yesterday, and hopes to complete the work today.
"The goal is to create additional habitat for marine life,' said Rep. William M.
Straus, D-Mattapoisett, who got $75,000 appropriated through the Legislature to
set up the program.
Fish like to congregate around the structures, which soon become encrusted with
vegetation and invertebrates, creating a habitat for species such as scup, black
sea bass, and tautog, which seek out bottom areas for food and shelter. Lobsters
also are likely to be to be attracted to the area, along with secondary users
such as striped bass and bluefish.
"This place is going to be a big scup area next year," predicted Lt. Peter
Hanlon of the state environmental police. A 25-foot patrol boat and UMass
Dartmouth's Lucky Lady ferried the state officials, Reps. Straus and John Quinn,
D-Dartmouth, and reporters out to watch the placement of the reef units.
The project is a joint undertaking of the state Division of Marine Fisheries and
the UMass Dartmouth Center for Marine Science and Technology.
"There is real potential in education, real potential in research, and I believe
real potential for economic development," said Dr. Peter H. Cressy, chancellor
of UMass Dartmouth.
"It's another way station for us to gather data," he added. "It should give us
some real good science, and not by guess or by God."
Karen Rypka, coordinator of the project for the state Division of Marine
Fisheries, said the concrete reef balls and pallets have proven "to be the best
type for reef materials."
"Tires have been proven over the years not to be the best reef material," she
said. "Bundled together, they have a tendency to get blown apart in a storm."
Divers are expected to check the configuration next week, she said. "This time
of year, however, the visibility is a little tough in Buzzards Bay."
The artificial reef was being laid with a cluster of 20 balls laid at
the center, with the smaller pallet balls in perimeter groupings. Some of the
larger balls will be laid outside the site.
The concrete contains micro silica for added strength, is resistant to abrasives
and has a pH content similar to natural seawater. The reef balls, weighing 3,000
to 3,500 pounds each, are about 4 feet high and 6 feet in diameter. Reef pallets
weigh 1,200 to 1,400 pounds and are about 3 feet high and 4 feet in diameter.
"We're going to start monitoring this site on a regular monthly basis, and also
work with the Mass. Division of Marine Fisheries," said Jeff Turner, the UMass
Dartmouth scientist who has spent 10 years collecting data on things such as
water chemistry and plankton at various sites in Buzzards Bay.
Mr. Diodati said the state hopes the information gathered from the Salters Point
reef will allow the state to expand the program in the future.
"We hope to develop a second project or expand the project here in Buzzards
Bay," he said. "I'd like to see one more project in Buzzards Bay or in some
other area of state waters,"
He said the state might be able to use fisheries restoration funds it receives
through the federal Wallop-Breault Fund to expand the project.
