VIMS Articles
Global environmental abundance of microplastics (MPs) is increasing. MPs may sorb hydrophobic organic contaminants (HOCs), accumulate in and cause deleterious effects on exposed organisms. This study investigated and compared the accumulation and effects of MPs and MP-associated PCB in the two indigenous aquatic organisms in Viet Nam, the white hard clams, Meretrix lyrata, and the giant river prawns, Macrobrachium rosenbergii. The test organisms were exposed to either polyethylene microbeads (PEMBs), waterborne polychlorinated biphenyl 153 (PCB-153), or PEMB-associated PCB-153 (PEMB-PCB) over 28 days. Organismal MP accumulation, survival, and weight gain were examined at various sampling intervals. In general, MP …
Spatial Assessment Of Slender Madtom (Noturus Exilis) Diets Within The Illinois Bayou, Brendon K. Mitchell
Spatial Assessment Of Slender Madtom (Noturus Exilis) Diets Within The Illinois Bayou, Brendon K. Mitchell
ATU Research Symposium
The Slender Madtom (Noturus exilis) is a common species with a widespread distribution across the Mississippi River basin. In Arkansas, they can be found in upland rivers/streams in the Arkansas River and White River watershed. Very little data has been collected on the diet of this species and how it varies. We wanted to spatially assess the diet of Slender Madtoms. Slender Madtoms were sampled from 8 sites in the Illinois Bayou watershed using seines and kick nets. Small-scale gastric lavage was used to extract diet data from all individuals. All prey items were preserved and identified to the genus …

Microhabitat Use Of The Highland Darter (Etheostoma Teddyroosevelt) In The Illinois Bayou Watershed Of Arkansas, Colton W. Morris
ATU Research Symposium
Highland Darters (Etheostoma teddyroosevelt) are an Ozark regional endemic species, occurring in the Arkansas River and upper White River systems of Arkansas, Kansas, Oklahoma, and Missouri. There have been very few studies on this species, specifically those that have quantified the habitat use of this species across its range. A new study was needed to fill in the knowledge gap of microhabitat use by the Highland Darter in Arkansas. We wanted to address this knowledge gap by assessing the microhabitat use of this species in the Illinois Bayou watershed in Arkansas. Highland Darters were observed during snorkel surveys at known …

Mussel Communities Of Two Impacted Tributaries In The Arkansas South Central Plains Ecoregion, Jimmy Hall, Seth Drake, Parker Brannon, Savannah Wise
ATU Research Symposium
Anthropogenic influences such as mining and water quality degradation from wastewater effluents and agricultural runoff heavily impact freshwater mussel communities. The South-Central Plains (SCP) Ecoregion in Arkansas contains the Smackover Formation, an area that has been exploited for its oil with high frequency of drilling. In 1922 the Smackover pool in Union County was found and quickly became one of the world's most productive oil sites. Hurricane Creek and Smackover Creek, two tributaries within the Ouachita River basin, have experienced negative impacts from oil exploration and mining. However, to our knowledge, mussel communities in these creeks have not been assessed …
Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand
Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand
Honors College
Coastal shellfish aquaculture has expanded substantially in recent years in Maine and New England as traditional wild fishery stocks have declined. As shellfish aquaculture has expanded, producers have become more concerned about marine worm pests (i.e., polychaetes) that infest cultured bivalves. In particular, worms from the genus Polydora (also known as “polydorids”) burrow into oyster and scallop shells where they feed and deposit mud. Bivalves cover over the muddy burrows creating blisters that can decrease their market value and hinder growth. Farmers and researchers have identified methods to control infestations of P. websteri, one common species of shell-boring worm. However, …

Maine Lobstermen's Association Whale Update, Amber-Jean Nickel, Maine Lobstermen's Association
Fisheries
The Maine Lobstermen's Association “has been closely following the death of Right Whale 5120 found dead on Martha’s Vineyard on January 28th. The MLA was shocked and dismayed when NOAA Fisheries announced on February 14th that the rope removed from the deceased whale 'is consistent with the rope used in Maine state water trap/pot buoy lines.’”
“Maine lobstermen have made many changes to how we fish to avoid harming a Right whale which makes this news hard to believe. As we move forward, MLA will push back on NOAA’s finding until the industry’s questions about the entanglement and how NOAA …
Dietary Shifts And The Need For Increased Sustainability Approaches In The Global Aquaculture Seafood System, Darien D. Mizuta
Dietary Shifts And The Need For Increased Sustainability Approaches In The Global Aquaculture Seafood System, Darien D. Mizuta
VIMS Articles
Recent shifts in the global dietary preferences have indicated the fast-growing choice for plant-based, or meat-reduced diets. Among the motivations for such choices, which are increasingly advocated by nations and environmental institutions, is the major concern with global environmental sustainability and impacts of food production systems. Incontestably, the animal food source industry is extremely diverse, and seafood production through the aquaculture value chain remains unfamiliar to key stakeholders possibly leading to an uncomprehensive view and often biased perception of the farming industry within the environmental context. Accordingly, I discuss the importance of seafood production systems, such as the fastest seafood …

Complex Dynamics Of Coral Gene Expression Responses To Low Ph Across Species, Veronica Z. Radice, Ana Martinez, Adina Paytan, Donald C. Potts, Daniel J. Barshis
Biological Sciences Faculty Publications
Coral capacity to tolerate low pH affects coral community composition and, ultimately, reef ecosystem function. Low pH submarine discharges (‘Ojo’; Yucatán, México) represent a natural laboratory to study plasticity and acclimatization to low pH in relation to ocean acidification. A previous >2‐year coral transplant experiment to ambient and low pH common garden sites revealed differential survivorship across species and sites, providing a framework to compare mechanistic responses to differential pH exposures. Here, we examined gene expression responses of transplants of three species of reef‐building corals (Porites astreoides, Porites porites and Siderastrea siderea) and their algal endosymbiont communities …

The current climate change is caused by anthropogenic activities involving energy and industry usage that affect the temperature and climate of the Earth. The Paris Agreement on climate change is a commitment by some countries to act to address climate change by developing sustainably and emitting low levels of carbon dioxide (CO2). Changes in the oceans include temperature increases, acidification, and changes in currents, leading to decreased productivity in fishing and aquaculture. Integrated mangrove shrimp farming, known as silvofisheries, has been recognized as environmentally friendly cultivation. The implementation of silvofishery is a form of mangrove ecosystem management that integrates ecology …

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

A Year Of Wins For Farmed Animals, Lewis Bollard
General – Farm Animal Issues
Although the European Union shelved its ambitious farmed animal welfare reforms, there were other “wins” for farmed animals in 2023. There were 130 new corporate pledges to eliminate cages for laying hens and the worst abuses of broiler chickens. So far, over 1,000 corporate pledges have been fully implemented, and 39% of American hens, 60% of European hens, and 80% of British hens are cage-free, up from 6%, 41%, and 48%, respectively, a decade ago. The US Supreme Court upheld California’s Proposition 12, which bans the sale of eggs, pork, and veal from caged animals and their offspring in California. …
Status Survey Of Eight Rare Aquatic Macroinvertebrates In East Texas, Alexandra Randall
Status Survey Of Eight Rare Aquatic Macroinvertebrates In East Texas, Alexandra Randall
Biology Theses
Freshwater is essential to human existence. The health of each freshwater source is connected to the survival of pollution intolerant species of aquatic macroinvertebrates in the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa). A higher presence of EPT taxa equates to better water quality because their water bound larvae assist in maintaining clean freshwater environments and will not survive in highly polluted water. Human disruption to natural environments is causing increases in polluted freshwater, leading to decreases in the presence of EPT taxa. Texas Parks and Wildlife Department documentation shows major concern for the populations of eight EPT species of …

Oyster reefs provide a variety of important ecosystem services. However, the mortality rate of eastern oyster, Crassostrea virginica, the dominant species that produces oyster reefs in the northern Gulf of Mexico, is increasing at an alarming rate due to a variety of abiotic and biological factors. I examined how biophysical factors, including the less-studied fatty acid profiles of the suspended particulate matter on which oysters feed, influenced morphometric condition of C. virginica.
I sampled suspended particulate matter (SPM) and oysters in-situ in the western Mississippi Sound, which historically supported the majority of oyster production in Mississippi waters. Sampling …

The Influence Of Invasive Species On Fishers’ Satisfactions, Caroline M. Laplante
The Influence Of Invasive Species On Fishers’ Satisfactions, Caroline M. Laplante
School of Natural Resources: Dissertations, Theses, and Student Research
Invasives species are prevalent and widespread in North America. Outdoor recreational activities, such as fishing, introduce a point in which humans may interact with invasive species and have to adapt their own behaviors. Bigheaded carp in the Missouri River below Gavin’s Point Dam are a group of invasive fish species that were thought to be negatively relating to recreational fishers’ satisfactions. Using a content analysis and an importance-grid, we conclude that invasive species do not strongly relate to recreational paddlefish fishers’ satisfactions. Paddlefish fishers represent a small sub-set of recreational fishers in Nebraska and South Dakota. The content analysis revealed …
