Virginia Game Fish Tagging Program Annual Report 2019, Susanna Musick, Lewis Gillingham May 2020

Virginia Game Fish Tagging Program Annual Report 2019, Susanna Musick, Lewis Gillingham

Reports

Through 2019, the Virginia Game Fish Tagging Program (VGFTP) has maintained a 24-year database of records for tagged and recaptured fish. The program is a cooperative project of the Virginia Saltwater Fishing Tournament (VSFT) under the Virginia Marine Resources Commission-(VMRC) and the Virginia Institute of Marine Science (VIMS) of the College of William and Mary (under the VIMS Marine Advisory Program).


Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2019 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee Jan 2020

Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2019 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee

Reports

This report describes the results of the twenty-second year of a continuing study to estimate the relative abundance and assess the status of American shad (Alosa sapidissima) stocks in Virginia by monitoring the spawning runs in the James, York and Rappahannock rivers in spring 2019, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007). We also report on two fishery-independent monitoring programs using anchor gillnets in the Rappahannock River (year 2) and the Chickahominy River (year 5; a major tributary of the James River), to determine relative abundance and stock structure for the adult spawning run of river herring …


Feeding Time: How Nutrients Drive Phytoplankton Growth, Brianna Stanley Jan 2020

Feeding Time: How Nutrients Drive Phytoplankton Growth, Brianna Stanley

Reports

Grades: 9-12 Subjects: Biology | Environmental Science | Oceanography

This lesson plan helps students make the connection between the amount of nutrients present in an ecosystem and the resulting growth of phytoplankton in our coastal waters. This lesson takes this concept a step deeper, by exploring how the proportions of nitrogen and phosphorus in the environment create the ideal conditions for phytoplankton growth. Students will explore the concept of limiting factors and will work on both their graphing skills and their ability to compare ratios.


Isotopes In The Estuary: Conception And Application Of Stable And Radioactive Carbon, Derek Detweiler Jan 2020

Isotopes In The Estuary: Conception And Application Of Stable And Radioactive Carbon, Derek Detweiler

Reports

Grades: 9-12 Subjects: Chemistry | Environmental Science | Oceanography

In this interactive estuary-focused activity, students will examine stable and radioactive isotope data which provide information about the source and age of environmental samples such as plant and soil matter. Students will calculate average isotope ratios from five reference land types (forest, wetland, agriculture, industry, aquatic) and an unknown site within an estuary. Students will graph their calculated ratios and determine the land type that most impacts their estuary based on reference-to-unknown comparisons.

What different methods and new technologies are used to monitor harmful algae and the toxins that they produce?

Students will learn about how harmful algae threaten human health through the processes of bioaccumulation and biomagnification. In small groups, they will design a harmful algae monitoring program based on mock harmful algae data, and then they will test their monitoring program and discover some of the challenges and limitations of any monitoring plan that attempts to measure variable, natural events.


Wave Fever: The Climate Induced Range Expansion Of The Atlantic Marsh Fiddler Crab, Kayla Martinez-Soto Jan 2020

Wave Fever: The Climate Induced Range Expansion Of The Atlantic Marsh Fiddler Crab, Kayla Martinez-Soto

Reports

Grades: 9-12 Subjects: Biology | Environmental Science | Oceanography

In 2014, scientists found that the Atlantic marsh fiddler crab had extended its northern limit by ~90 miles to New Hampshire, which is in the Gulf of Maine. Range expanding species can alter salt marsh characteristics such as biodiversity and food webs. In this lesson, students will combine sea surface temperature data from a federal database and fiddler burrow densities from field photos to determine the relationship between ocean warming and range expansions.

Old Macdonald Had An Aquaculture Farm, Shantelle Landry Jan 2020

Old Macdonald Had An Aquaculture Farm, Shantelle Landry

Reports

Grades: 6 Subjects: Earth Science | Natural Resources

With this activity, students will learn the importance of aquaculture and how it can be used to manage a resource.


What's In The Muck? Benthic Sediment Characterization And Community Structure, Cristin Wright Jan 2020

What's In The Muck? Benthic Sediment Characterization And Community Structure, Cristin Wright

Reports

Grades: 9-12 Subjects: Biology | Environmental Science | Oceanography


Sediment classification and grain size can affect the types of organisms that live in the sediment. Some organisms prefer sandier sediment, while others love the fine-grained mud.

In this activity, students will classify sediment samples by grain size and plot their findings on a ternary plot. The students will then further investigate which benthic organisms live in the different sediments and which may be more resilient to a change in sediment classification.

What are harmful algal blooms and why do they occur?

In this lesson plan, students will run their own experiments to investigate how eutrophication can cause harmful algal blooms and investigate strategies for preventing them.
