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
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
"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
The project is a joint undertaking of the state Division of
Marine Fisheries and the UMass Dartmouth Center for Marine Science and
"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
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
Mr. Diodati said the state hopes the information gathered
from the Salters Point reef will allow the state to expand the program in the
"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.
