Mercury and Fish Consumption Advisories Issued for
Six Louisiana Waterways
On May 21. 2021, the Louisiana Departments of Health (LDH), Environmental Quality
(LDEQ), and Wildlife and Fisheries (LDWF) issued a series of fish consumption advisories
for six bodies of water. These most recent advisories include one new warning and updates
to five previously issued warnings.
The state issues precautionary advisories when unacceptable levels of mercury are detected
in fish or shellfish.
LDEQ conducted fish sampling, and LDH then used this data to determine the need for
additional advisories or to modify existing advisories. Each advisory lists the specific fish,
makes consumption recommendations, and outlines the geographic boundaries of the
affected waterways.
Bayou Chene and Bayou Lacassine
•	Includes Bayou Chene from its headwaters near Jennings to its confluence with
Bayou Lacassine, and Bayou Lacassine from its headwaters near Lacassine to its
confluence with Bayou Misere.
•	Women of childbearing age and children less than seven years of age should
consume no more than one meal per month" of largemouth bass and bowfin
(choupique, grinnel) combined from the advisory area; or should consume no more
than two meals per month of crappie, freshwater drum (gaspergou), smallmoulh

Because of mercury contamination, there are now fish consumption advisories for 49 waterways in Louisiana and
one for the Gulf of Mexico.
Louisiana fish consumption advisories are based on the estimate that the average resident eats four meals of fish
per month. Consuming more than this amount from local water bodies may increase health risks.
Mercury is an element that occurs naturally in the environment. Consequently, there are small amounts of mercury
in the sediments of streams, lakes, rivers, and oceans. Nearly all fish contain trace amounts of mercury. They absorb
mercury as they feed on aquatic organisms. Larger predator fish contain more mercury than smaller fish. To
minimize exposure to mercury, LDH recommends that smaller fish be consumed instead of larger ones.
People are exposed to low levels of mercury throughout their lives. Eating contaminated fish is one way we are
exposed to mercury. Health effects from harmful levels of mercury can include nervous system and kidney damage.
Young children and developing fetuses are more sensitive to the toxic effects of mercury. Therefore, consumption
advisories are issued at lower fish tissue concentrations for women of childbearing age and children under seven
years of age.

Dragonfly Larvae are Effective Bioindicators of Mercury Exposure in
Fish and Amphibians—Results of Citizen Science in 100 National
Parks and Protected Places
On July 7, 2020, a study was published about a national-scale assessment of mercury bioaccumulation in national
parks, using dragonfly larvae as biosentinels, through a citizen-science framework.
Environmental mercury in its organic form (methylmercury) biomagnifies through food webs, posing potential
health risks to fish, wildlife, and humans. Methylmercury in fish tissue is a leading cause of fish consumption
advisories in North America. Mercury trend detection in environmental media is needed for understanding the
success of mitigation efforts to reduce mercury exposure. Mercury measurements made in air, water, sediment, and
soil help document environmental sources and emissions, but are either poor or inconsistent predictors of mercury
concentrations within biota of associated food webs.

July 2021
Therefore, the U.S. Geological Survey (USGS) Ecologically-Driven Exposure Pathways Science Team implemented
a national scale study, supported by the USGS's Environmental Health Programs (Contaminant Biology and Toxic
Substances Hydrology), the National Park Sendee (NPS), University of Maine, and more than 4,000 citizen
scientists, to determine if dragonfly larvae could be useful bioindicators to help predict and understand wildlife
mercury exposure.
Dragonflies were selected as bioindicators because they address many of the
challenges associated with mercury measurements in other wildlife (including
the lack of consistency in species among sites; movements and migratory
behavior; and variations in factors such as body size, trophic position, and
growth rates), which can contribute to variation and uncertainty. Samples
were collected from 450 sites in 100 national parks and other protected places
by citizen scientists paired with trained NPS staff.
Variation in mercury concentrations among various families of dragonfly
larvae necessitated a conversion of concentrations to one common unit. The
scientists developed Aesluiid-equivalent concentrations using the relation
between mercury concentrations in Aeshnidae (the most commonly collected
dragonfly family in the study) and other dragonfly families. The Aeshnid-
equivalent mercury concentrations were positively correlated with mercury concentrations in four different fish
guilds (groups of species that exploit the same resources) and two types of amphibians (frogs and salamanders).
As an additional step, the team developed a tool (Integrated Risk Impairment Index) to inform potential wildlife
health risks using Aes/m/d-equivalent mercury concentrations and published information 011 mercury toxicity.
Based on this exercise, 10 percent of sites were below any of the estimated impairment categories, whereas 22,56,
11, and 1 percent of sites exceeded low, moderate, high, and severe estimated impairment categories, respectively.
This study demonstrates the use of dragonfly larvae as effective bioindicators of mercury exposure in several
freshwater taxa and established a sampling network for mercury on protected lands across the U.S. These findings
highlight the efficacy of carefully designed citizen science efforts to facilitate studies that would be otherwise
difficult to conduct because of large resource requirements. More information on this study can be found in an
associated geo-narrative.
The USGS Ecologically-Driven Exposure Pathways Science Team and their collaborators are continuing to
develop predictive tools to understand the environmental pathways of contaminant exposure and to understand the
effects of exposure on individuals, populations, communities, and entire ecosystems. Future applications of
dragonfly larvae monitoring could be useful for understanding the drivers of contaminant availability to aquatic
food webs; predicting the potential risk to vertebrates; and evaluating the effectiveness of mitigation actions to
reduce contaminant exposure.
The Environmental Health Program (Contaminants Biology and Toxic Substances Hy drology) of the USGS
Ecosystems Mission Area supported this study.

Park, Montana. Dragonfly larvae were selected

distributed and abundant, are key
components of aquatic food web energetic
pathways, are relatively long-lived, and show

Hawaiian Fishponds: Providing Physical and Cultural Sustenance
Once, nearly 500 fishponds provided local Hawaiian communities with aquacultured seafood. Fishponds served as
a unique part of an integrated agricultural and ecosystem management regime today known as the ahupua'a
system. A societal move toward more centralized governance and economics, time, natural disasters, development,
and cultural-economic changes led to only four working fishponds by the dawn of the 21st century. These fishponds
offer the opportunity to provide physical and cultural sustenance. An effort is underway to restore the pond
structures and reconnect communities to their aquaculture past. KUA, an innovative community-based initiative,
supports network efforts to build capacity to restore and care for these traditional fishponds.
"KUA means backbone, and the organization serves as the backbone that connects multiple communities working
to restore Hawaiian bio-cultural resources, including efforts to restore fishponds," said Kevin Chang, Executive
Director of KUA. "The organization is about more than the physical restoration, it also connects our communities to
each other, their history, cultural foundation, and future." In a culture that honors sustainability, fishponds
symbolized the connection between communities, the " aina (land), and mo'omeheu (culture).
KUA has a dedicated fishpond collective known as Hui Malama Loko I'a, meaning network that cares for fishponds.
It has worked since 2013 to foster fishpond restoration efforts. "Through our network we provide resources and in-
person meetings that host two staff members from each fishpond site, that is about 80-120 people gathering
annually to share lessons learned, opportunities, and research," said Brenda Asuncion, Hui Malama Loko I'a
Coordinator.
"Today we have around 40 fishpond sites across the islands in different stages of restoration," added Asuncion.
"There are no site standards or requirements for the Hui; each site has different goals according to their watershed
and community structure."
Restoration Through Old and New Technologies
To restore and improve fishponds, Hawaiian aquaculture practitioners are combining contemporary science with
traditional practices and knowledge to adapt to today's sustainability challenges. Restoration of neglected sites still
involves communities lending a hand and sometimes leading efforts. "Building pond walls today, much like it did
hundreds of years ago, still involves community members coming together to remove sediment and constructing

rock walls by hand," said Asuncion. She notes they are also a common site for modern research with agencies and
organizations studying environmental conditions like water quality, climate impacts, and chemistry in the
fishponds.
Since the very first fishponds, the structures have been designed to recruit smaller fish to enter the ponds through a
weir-type structure. These weirs are usually an opening in the rock walls covered by stick grates to allow smaller fish
to enter the ponds. Once in the pond fish feed on the site's rich vegetation until they reach harvest size. As the
environments around the fishpond sites have also changed, getting smaller juvenile fish to enter the pond can be
difficult. This is where contemporary science can offer a solution, exploring the idea of partnering with hatcheries or
labs to stock native fineerlings.
Nutritional Relevance Then and Now
A historic quote attributed to Samuel Manaiakalani Kamakau described fishponds as "things that beautified the
land, and a land with many fishponds was called a 'fat' land." While the exact date of the individual fishpond
constructions is unknow n, Hawaiians typically built many of their ponds between the years 1200 and 1600. The age
of these builds can lead many to think of the sites as relics of a past time. However, restored ponds are as socially,
economically, and environmentally important today as they were 800 years ago.
Just as in centuries past, island residents worry about food security due to their isolation in the Pacific Ocean. "We
are located 2,500 miles from the mainland U.S.; this means our dependence on food imports is high," said Chang.
In fact, nearly 90 percent of Hawaii's food is imported, making it particularly vulnerable to global events that might
disrupt shipping and food supplies. "These fishponds were a technology used to leverage the commons to feed the
people, but today we also see their potential to restore our
commons for the people," added Chang.
These traditional fishponds offer a sustainable way to increase
access to local food year round. The ponds also offer community-
based economic development opportunities for sites to sell their
aquacultured seafood. This would allow fishpond organizations to
keep money in the local community and to fund education and
outreach activities at the ponds.
Vision for the Future
Through KUA, the Hui Malama Loko I'a community will continue
to support fishponds. Along with providing sustainable food and economic opportunities, Asuncion and Chang hope
these ponds can also restore a sense of place-based management and a relationship with the land.

National Fish Habitat Partnership Projects to Enhance Recreational
Fishing and Restore Habitat
On May 5, 2021, the National Oceanic and Atmospheric Administration (NOAA) funded four projects designed to
enhance recreational fisheries engagement and restore habitat through the coastal National Fish Habitat
Partnerships. Saltwater recreational fishing is a part of the fabric of coastal communities, and anglers make critical
contributions to the conservation of fish habitat nationwide. NOAA Fisheries is committed to collaborating with the
recreational fishing community and supporting access to sustainable saltwater recreational opportunities. These
projects will actively involve anglers in habitat restoration efforts that will benefit coastal communities and
economies.
Recreational Engagement and Ecological Learning Series in Louisiana
Sponsoring Partnership: Southeast Aquatic Resources Partnership
Anglers Bettering Louisiana's Estuaries, Louisiana Sea Grant, and the Southeast Aquatic Resources Partnership will
work with local charter boat captains. They will provide an experiential learning program about Louisiana habitat
restoration and coastal planning. The program will include classroom sessions, field days, and time on the water.
During the field days, the charter captains will pot, plant, and monitor black mangroves to improve habitat for
juvenile fish, shrimp, and crabs. The program will also recruit local high school students to participate in the field
days. At the end of the program, the charter boat captains will take these students on two recreational fishing trips.
They will teach the students to fish and share what they have learned about Louisiana habitats and their connection
to fish.
Outreach and Education at Bill Burton Fishing Pier in Maryland
Sponsoring Partnership: Atlantic Coastal Fish Habitat Partnership
As part of its Living Reef Action Campaign. Coastal Conservation Association (CCA) Maryland will expand outreach
and education efforts at the Bill Burton Fishing Pier. The pier is frequently visited by a diverse community in
Dorchester County, Maryland, and is an access point to the Choptank River Habitat Focus Area. In 2014 and 2015,
oyster reef balls were successfully deployed off the pier to provide habitat for striped bass, drum, shad, blue crab,
and other species. In this project, CCA Maryland will host several public oyster reef ball building events to construct
and deploy more reef balls at the site. The project will also add six bilingual (English and Spanish) signs to inform
recreational anglers of the new and previously deployed reef balls at this site. The signs will describe their purpose,
the habitat types along the pier, fishing regulations, gear disposal instructions, and seafood consumption safety. An
underwater web camera will be installed at the reef and live video will be displayed at the nearby visitor center. A
video about the resources at the pier will also be produced and shared with the local community.

freshwater wetlands back into salt marsh habitat. Restoring tidal connectivity in this 32-acre area will provide
critical nearshore habitat for juvenile Chinook salmon. It will restore ecosystem processes at a key site along
migratory salmon routes in and out of Puget Sound. The project will engage the local North Kitsap Puget Sound
Anglers and other local fishers to collect data before and after restoration and to help with education and outreach
around the project and its importance. This may include conducting interviews with fellow anglers, documenting
observed species in the habitat, and collecting post-restoration monitoring data. The project supports the NOAA
Fisheries Puget Sound Chinook Recovery Plan and is integrated with regional salmon recovery efforts.
Documenting Coastal Cutthroat Trout Distribution in Alaska
Sponsoring Partnership: Western Native Trout Initiative
The Alaska Department of Fish and Game and the Western Native Trout Initiative will survey potential habitats
used by Coastal Cutthroat Trout (CCT) at the edges of the species' range in Alaska. Anglers throughout the region
will sample the areas where CCT are predicted to occur—taking genetic and tissue samples, and recording
demographic data. Findings of the survey and field sampling will be disseminated to angler and interest groups, and
will be used to identify the streams where CCT occur. The identified streams will be submitted to the Alaska
Anadromous Waters Catalog, which provides habitat protection under state law. This type of protection will
proactively conserve these important habitats at the northern and westernmost edge of the species' range. This area
is expected to become more important as the species' range shifts due to climate change.
The projects are funded through NOAA Fisheries' Habitat Protection Division and Recreational Fisheries Initiative.
in partnership with:
•	Atlantic States Marine Fisheries Commission
•	Pacific States Marine Fisheries Commission
•	Gulf States Marine Fisheries Commission
This is the third year that this funding opportunity has been offered. Projects were selected based on active
engagement of recreational fishing partners in habitat protection, restoration, or monitoring efforts, and the
potential to build long-term relationships with those partners.

New Fish Consumption Advisory App
Advisories can now be viewed on the new GIS Fish Consumption Advisory App! This app shows up to date
advisories, fish tissue sampling sites, and public boat landings across the state. Simply click on a highlighted
waterbody to learn more about advisories at that location or use the search feature to locate specific waterbodies on
the map. The "About" pop-up provides more guidance on what advisories are as well as additional resources for
more information.
Fish consumption advisories are issued by waterbody by the South Carolina Department of Health and
Environmental Control (SCDHEC) with support provided by the South Carolina Department of Natural Resources
(SCDNR).
For detailed information, please access:
•	Fish consumption advisories booklet
•	Fish consumption advisories table
Fish is a lean protein that is a good source of omega-3 fatty acids. However, some fish contain chemicals at levels
that may be harmful to human health. Fish consumption advisories are recommendations for the consumption of
recreational caught fish from South Carolina public waters. A fish consumption advisory is a warning targeted to
either the general population or specific at-risk groups such as babies, children under 14, women who are nursing,
women who are pregnant and women who plan to become pregnant.
An advisory will list a lake, stream, or river in South Carolina and describe the type and amount of fish safe to eat
from that waterbody. Simply click on the waterbody of interest to see the advisory or search by name.
Displayed waterbody boundaries are representative of the resource and not intended to depict exact boundaries. If a
waterbody or type of fish is not listed in the tables, it means that SCDHEC has not issued any consumption advice.
Here are the reasons why SCDHEC may not issue an advisory:
•	The waterbody may not have been sampled.
•	There may not be enough data.
•	The waterbody is privately owned.
