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 …

West Coast Rock Lobster Resource Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia May 2024

West Coast Rock Lobster Resource Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia

Fisheries management papers

Harvest strategies for Western Australia’s (WA) aquatic resources are formal documents developed by the Department of Primary Industries and Regional Development (DPIRD, the Department) to support decision-making processes that ensure the outcomes are consistent with the principles of Ecologically Sustainable Development (ESD; Fletcher 2002a) and Ecosystem Based Fisheries Management (EBFM; Fletcher et al. 2012). Harvest strategies are a key component of all contemporary fishery management systems and a requirement for certification under the Marine Stewardship Council (MSC). The objectives of ESD are reflected in the objectives of the Fish Resources Management Act 1994 (FRMA) and the Aquatic Resources Management Act …


Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay Annual Progress Report: 2023 - 2024, Jack R. Buchanan, Mary C. Fabrizio, Troy D. Tuckey May 2024

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay Annual Progress Report: 2023 - 2024, Jack R. Buchanan, Mary C. Fabrizio, Troy D. Tuckey

Reports

The 2023 juvenile Striped Bass abundance index was 4.26 and was significantly lower than the reference mean of 7.77 for the period 1980 to 2009. Abundance indices were below average in the James and Rappahannock rivers and average in the York River in 2023 compared with the river-specific reference means (1980-2009). Relatively low catches of young‐of‐the‐year Striped Bass from sites upriver and downriver of core nursery areas suggest juvenile Striped Bass largely remained within core nursery areas in 2023.

Indices of abundance were calculated for three additional economically and recreationally important fishes in Virginia waters. Juvenile White Perch abundance indices …


Ecological, Molecular, And Electron Microscopical Investigations Of The Distribution Of Shell-Boring Polychaetes Along The Coast Of Maine, Emma Tomasetti May 2024

Ecological, Molecular, And Electron Microscopical Investigations Of The Distribution Of Shell-Boring Polychaetes Along The Coast Of Maine, Emma Tomasetti

Honors College

Blister worms are polychaete worms that live in various calcareous materials such as dead shells, red algae, limestone, and cinder blocks, along with cultured shellfish, such as oysters or sea scallops. These worms can be considered a pest due to their nature to burrow into their host’s substrate and create blisters that then fill with mud and detritus. In chapter 1, I worked closely with an oyster farm looking at the reproductive status of one species of blister worm, P. websteri, and the efficacy of cold storage as a method of ridding oysters of P. websteri. For chapter 2, I …


Phenotypic Plasticity In Pigmentation: Investigating Coloration Patterns In Anablepsoides Hartii Population Responses To Environmental Variation, Jasdeep Kaur May 2024

Phenotypic Plasticity In Pigmentation: Investigating Coloration Patterns In Anablepsoides Hartii Population Responses To Environmental Variation, Jasdeep Kaur

2024 Spring Honors Capstone Projects

In this study, we investigated the color-changing capabilities of Trinidadian killifish, Anablepsoides hartii, through exposure to varied color conditions over defined periods of time. Our experiment aims to understand adaptive responses when killifish are subjected to different color backgrounds, exploring their mechanisms to change color. By subjecting the species to different environmental color variations, we sought to discern color change patterns, which could indicate adaptive responses related to camouflage, stress, behavior clues, and physiological adjustments. Carefully controlling environmental factors, we monitored and documented the fishes’ color changes, aiming to provide insights into the interplay between fish’s developmental plasticity and its …


An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny Apr 2024

An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny

NOAA Technical Reports and Related Materials

Flash flooding occurs each summer in eastern Nebraska and western Iowa. While 10-inch rains are extraordinary, it is not uncommon to have at least one excessive rain event during the annual convective season. A significant flash flood occurred in east central Nebraska and western Iowa the night of August 6, 1999 into the morning of August 7, 1999. Antecedent hydrologic conditions limited the loss of life, however considerable property damage resulted as the heavy rain fell over the urbanized areas in eastern Nebraska and western Iowa.

Several flash flood ingredients came together over the area. These meteorological factors are typical …


Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand Apr 2024

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 Feb 2024

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 Feb 2024

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 …

Long Term Sustainable Use Of Demersal Gillnet And Demersal Longline In Western Australia’S Temperate Shark Fisheries - Fisheries Research Report 340, Matias Braccini, Jack Parker, Daniela Waltrick, Maddison Watt, Nick Blay, Clinton Syers

Fisheries research reports

The Temperate Demersal Gillnet and Demersal Longline Fisheries (TDGDLF) are one of the main commercial shark fisheries in Australia. Most fishers in the TDGDLF use demersal gillnets to target sharks with scalefish taken in smaller amounts. Demersal longlines are also permitted but are not widely used. Demersal gillnets are size selective, but they do not necessarily discriminate among species, catching target and non-target species.

The Western Australian Fishing Industry Council (WAFIC) received funding as part of the Australian Government’s Our Marine Parks Grants Program to undertake research on the TDGDLF. This project was administered under the direction of a steering …


Animal Conservation In St. Louis, Kate O'Sullivan Jan 2024

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 …

A Year Of Wins For Farmed Animals, Lewis Bollard Dec 2023

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. …

The Influence Of Invasive Species On Fishers’ Satisfactions, Caroline M. Laplante Dec 2023

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 …
