This April, several months ahead of when the water had warmed up, homeowners
and businesses on the Navesink and Shrewsbury Rivers were cop-
and washing up on the beach. The cause was mystifying.
the herring family primarily harvested for bait and non-food commercial purposes.
In a recent report from the New Jersey Department of Environmental
Protection, the cause is bacterium called vibrio anguillarum. The NJDEP adds
that bunker appear to be the only species impacted. They may be more sus-

ing nature which increases transmission of the bacterium.
Jody Sackett, of the Rumson Environmental Commission, said, “Menhaden
are a more environmentally sensitive species, and function like the canary
in the coal mine to warn us of problems in our waterways. They are warning that
from sewer, septic and storm water runoff, as well as climate change.” Sackett,
a lifelong environmentalist, has a bachelor’s degree in aquatic environments
from Allegheny College and a master’s in environmental sciences from the
Ohio University. She is also an educator and program administrator for the NJ
Sea Grant Consortium.
She continued, “Part
of the problem is excessive
stormwater runoff. Rainwater
picks up trash, bacteria,
heavy metals, lawn
chemicals or fertilizers and
other contaminants along
the way to storm sewers,
which carry this water directly
into the nearest receiving
waterway.”
Sackett recommends homeowners reduce their use of landscaping
fertilizers, which can over-enrich waterways and encourage algae and
bacterial blooms that impact aquatic life.
She also recommends using simple green infrastructure to stop or
slow the stormwater runoff. Green infrastructure comes in various forms
– bioswales, rain gardens, permeable pavements and other bioretention
systems. A rain garden or bioswale is just a shallow indentation in the
ground which is planted with vegetation that collects rainfall runoffs, allowing
the rainwater to slowly percolate through the soil to the groundwater.
Planting sturdy native species in the bioswale translates into a
pretty garden and nearly maintenance-free rain gardens that also reduce
Other green infrastructure techniques include disconnecting gutter
downspouts and installing rain barrels or a bioswale to catch the heavy
house always helps too, or interspersing pavement with small mini-rain
gardens, bioswales, trees, or planter boxes to catch rainwater before it
enters the waterways.
Sackett added, “Rumson will be incorporating green infrastructure
to better manage our stormwater and create healthier suburban and
aquatic environments. Please take a minute when you see a rain garden
or bioswale or permeable pavement and admire how its simple beauty is
making Rumson and the communities a cleaner place to live.”

should be avoided as a precaution. Handling of dead or unhealthy ap-

gloves.
Menhaden die-offs are expected to continue in the near term. The
NJDEP will continue to provide information to local governments and
and become part of the nutrient cycle in affected waterways. To report a
