Dear Commissioners:
The Massachusetts Division of Marine Fisheries (MA DMF) has reviewed the Notice of Intent
by Shannon Smith to stabilize the coastal bank, conduct salt marsh restoration activities, and to
install oyster bags/castles within the intertidal area of Barnstable Harbor at 0 and 87 Salten Point
Road in the Town of Barnstable. The project was reviewed with respect to potential impacts to
marine fisheries resources and habitat.
The project site lies within mapped shellfish habitat for northern quahog (Mercenaria
mercenaria) and softshell clam (Mya arenaria). Waters within the project site have habitat
characteristics suitable for these species. Land containing shellfish is deemed significant to the
interest of the Wetlands Protection Act (310 CMR 10.34) and the protection of marine fisheries.
The project site includes existing salt marsh vegetation. Salt marsh provides a variety of
ecosystem services, including habitat and energy sources for many fish and invertebrate species
[1-2]
Barnstable Harbor acts as winter flounder (Pseudopleuronectes americanus) spawning habitat.
Winter flounder enter the area and spawn from February through May; demersal eggs hatch
approximately 15 to 20 days later. The Atlantic States Marine Fisheries Commission has
designated winter flounder spawning habitat as a “Habitat Area of Particular Concern” (HAPC).
In the latest stock assessment, the Gulf of Maine winter flounder biomass status is unknown and
overfishing is not occurring [3]. Given the unknown biomass status of the winter flounder stock,
every effort should be made to protect the species and its spawning habitat.
The project site lies within a horseshoe crab (Limulus polyphemus) spawning area and the
species has been recorded nesting nearby at Blish Point. Horseshoe crabs deposit their eggs in
the upper intertidal regions of sandy beaches from late spring to early summer during spring high
tides. Adult crabs congregate in deep waters during the day while they wait to spawn on nearby
beaches at night. Eggs hatch approximately two to four weeks later. The 2024 benchmark stock
assessment indicates that the New England horseshoe crab stock status continues to be neutral
[4]. Continued efforts should be made to protect the species and facilitate further stock
improvement
MA DMF offers the following comment for your consideration:
Shoreline Stabilization
2
• MA DMF supports the applicant’s proposal to protect the leading edge of the salt marsh
with coir logs or matting, cobble and sediment, and native planting provided there is a
monitoring plan.
• MA DMF supports the applicant’s proposal to restore the elevation of the small salt
marsh area landward of the proposed fiber roll array.
• A time of year (TOY) restriction should be observed to protect sensitive life stages of
horseshoe crabs. No sediment deposition or bank stabilization activities other than
planting should take place May 1 – July 31 of any year to protect sensitive life stages of
horseshoe crabs [5].
• A salt marsh monitoring plan is not included in this proposal. Key details such as the
expected frequency of regular check-ins, how and who will determine if an intervention
is necessary, and what will occur if the proposed project is not successful should be
included in a monitoring plan. MA DMF recommends a comprehensive monitoring plan
that includes a monitoring schedule and best management practices to limit the potential
of generating marine debris if the coir rolls are not successful or if they are co mpromised.
• Salt marsh restoration of this type is uncommon; therefore, MA DMF would appreciate
seasonal updates (every 3 months) until the site is considered “restored”. Updates should
include photographs, a short narrative, and should be sent to amanda.davis@mass.gov.
• Fuel spills from refueling of construction equipment will adversely impact sensitive
resource areas. Impacts to resource areas can be avoided by prohibiting all land-based
equipment from being refueled on-site. If equipment is refueled on-site, adequate
containment and clean up material should be required to minimize impacts .
Placement of Oyster Bags and Oyster Castles in Intertidal Area
• At this time, MA DMF can not fully support placing oyster bags and oyster castles within
the intertidal and subtidal area of Barnstable Harbor. Barnstable Harbor is a high energy
system and structures placed within the subtidal and intertidal area have potential of
becoming marine debris by becoming lose, stuck, or buried.
• This area is frequently used by commercial and recreational shellfish harvesters. The
placement of oyster bags and oyster castles in the intertidal and subtidal area will displace
suitable and productive quahog, razor clam, and softshell clam habitat.
• If approved, and monitoring and intervention plan should be developed and a shellfish
mitigation plans should seek input and expertise from the Barnstable Shellfish Constable.
• If approved, the applicant will likely need to file for a DEP Chapter 91 Waterways permit
and a General Permit.
• As an alternative, the addition of ribbed mussels along the leading edge of the restored
marsh could be considered as an alternative way to stabilize the marsh without altering
the intertidal flats and subtidal area.
Questions regarding this review may be directed to Amanda Davis at amanda.davis@mass.gov.

Amanda Davis
