Comparative Accumulation And Effects Of Microplastics And Microplastic-Associated Pcb-153 In The White Hard Clam (Meretrix Lyrata) And Giant River Prawn (Macrobrachium Rosenbergii) Following Chronic Exposure, Bao-Son Trinh, Lien Thi Le, Loc Minh Tran, Gunther Rosen, Robert C. Hale

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

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

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, …

This document contains the background information used to support the ERA risk scoring process, and a summary of the workshop discussions that were relevant to the risk scoring. The background information includes an overview of Western Australian commercial fisheries that access the Resource, focusing primarily on the Octopus Interim Managed Fishery (OIMF), Cockburn Sound Line and Pot Managed Fishery (CSLPMF), …

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

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 …

Animal Conservation In St. Louis, Kate O'Sullivan

Undergraduate Research Symposium

St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …

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 …

Capfish Project Report : Phase 1 Outcomes And Summer Academy For The Mediterranean, World Maritime University

Reports

Illegal, unreported and unregulated (IUU) fishing is a complex and multifaceted problem, with disastrous consequences for aquatic ecosystems, coastal communities, fishers and fish workers, and economic and national security. Over the past three years, the CAPFISH Project has strengthened capacity to fight IUU fishing by providing training and educational materials to developing country administrations around the world, most recently with a two-week regional Summer Academy for the Mediterranean. The Academy ran for two weeks and targeted delegates from fisheries administrations in developing countries in North Africa, the Middle East, and Southeast Europe, as a way to promote inter-regional learning and …
