From the Director

Spring is here, and the weather isn't the only thing that is heating up! In this newsletter, you are going to learn about our recently funded projects, hear about progress on existing projects, meet new employees, and say farewell to a key member of our team. So much to talk about!

Our $1,000,000 federal grant (shoutout to U.S. Senators Ben Cardin and Chris Van Hollen) is firing on all cylinders. Through this grant, we have: established four new Chesapeake Bay carbon monitoring locations; acquired a 25-foot research vessel to support our long-running blue crab survey; hired Randy Feris - our new Coastal Operations Specialist; and on-boarded five interns (part of a 11 student cohort this summer).

Since I spoke to you last Fall, PEARL has been on fire with new grants and contracts. PEARL researchers serve as Principal Investigator in two(!) Maryland Sea Grant proposals recommended for funding by Maryland Sea Grant. The two research grants will leverage PEARL expertise and facilities in very different ways. In research led by PEARL’s Aquaculture team, we will be working to address a key obstacle in soft-shell clam aquaculture by reducing summer mortality of this species. In research led by PEARL’s Environmental Economics team, we will be working closely with Morgan main campus faculty, UMCES CBL faculty and South Baltimore communities to co-produce research that will improve access to coastal spaces for community residents.

Other exciting research projects kicking off include another soft shell clam project funded by the U.S. Department of Agriculture, a project estimating the economic impacts of harmful algal bloom funded by the U.S. Army Corps of Engineers, an Economics Aquaculture Collaborative project funded by NOAA, and a Chesapeake Bay Blue Crab Stock Assessment project funded by the Atlantic States Marine Fisheries Commission. These projects involve partnerships across the University of Maryland, Virginia Tech, University of Maine, and other academic institutions. All told - six new projects bringing just over $1,000,000 research funds to the Morgan State PEARL.

Finally, a quick plug to promote PEARL’s social media presence. Our amazing Technology Support Specialist Monique Reed is taking our social media game to the next level, highlighting all sorts of interesting and exciting things happening with PEARL research and education. Last month, we shared a video of two 11-day old soft shell clam larvae involved in an old-fashioned sibling face-off. Please consider following and engaging through Instagram (and Facebook), to keep up to speed on the latest and greatest at the Morgan PEARL.

Best, Scott Knoche

New Equipment and Test Sampling for the Biogeochemistry Lab!

Thanks to the Federal Earmark and support from the National Science Foundation, the Biogeochemistry Lab has acquired and installed new monitoring equipment! This includes a Carbon, Hydrogen, Nitrogen, Sulfur, Oxygen (CHNS/O) Analyzer which will be used to study solid samples, a Total Organic Carbon Analyzer (TOC-L) with a Total Nitrogen Module (TNM-1) for liquid samples, and a spectrophotometer to study colored dissolved organic matter (CDOM). The first two instruments are used to study concentrations of carbon and organic matter in the water, while the spectrophotometer is used to study where that organic matter came from and what is likely to affect it in the future.

Here is an example of how the Biogeochemistry Lab collects samples for the two projects. An automatic water sampler is set on a dry surface, and tubing extends out to collect water. This picture is from the shoreline restoration site at Jefferson Patterson Park and Museum

Dr. Amanda Knobloch’s Biogeochemistry Lab is organized around two core projects that shed light on the coastal carbon cycle. The first project compares carbon cycling in tidal marshes and oyster aquaculture facilities. Climate change and land use change have led to the loss of tidal marshes throughout the Chesapeake Bay, while the increased demand for seafood has led to a greater number of oyster aquaculture farms. Tidal marsh and oyster farms have the potential to affect the coastal carbon cycle in similar ways, and this study examines whether oyster farms could replicate tidal marsh contributions to the coastal carbon cycle This study will take place in three locations: Jefferson Patterson Park and Museum (location of PEARL), an oyster aquaculture facility and marsh along the Potomac River, and the oyster aquaculture facility and tidal marsh at UMCES Horn Point Laboratory on the Eastern Shore.

The second project aims to understand and compare carbon cycling across three different coastal environments: an oyster aquaculture facility, a tidal marsh, and a shoreline affected by shoreline restoration activities.

As this program is just getting started, a test sampling was recently conducted to ensure that our sampling equipment works and our sample processing procedures were appropriate After a lot of trial and error, we were able to successfully complete a test sampling and process the water samples. The full sampling program will begin in June 2024.

The PEARL economics team is launching three different projects supported by Maryland Sea Grant, the US Army Corps of Engineers, and the National Oceanic and Atmospheric Administration Office of Aquaculture.

Baltimore BLUE-CORE: BLUEspace COllaborative REsearch for Urban Coastal Access and Climate Resilience in South Baltimore

The Baltimore BLUE-CORE project is supported by Maryland Sea Grant and will be led by the PEARL Environmental Economics team (Dr. Scott Knoche and Dr. Kehinde Ojo) in collaboration with two Morgan State University faculty (Dr. Samia Kirchner from the School of Architecture and Planning and Dr. Mark Barnes from the College of Liberal Arts) and a research professor from UMCES CBL (Dr. Lisa Wainger). While Baltimore City boasts a 61-mile coastline that supports international commerce, maritime activities and waterfront businesses, underserved coast-adjacent South Baltimore neighborhoods such as Brooklyn, Curtis Bay, Cherry Hill, and Brooklyn Park have limited access to the City’s coastal waterfront. This limited access prevents residents from realizing the physical and mental health benefits of these “blue spaces” and also hinders the equitable distribution of climate resilience benefits. This project aims to develop and enhance stakeholder relationships, producing collaborative research that will ultimately

Economic Valuation of Harmful Algal Bloom Control in Freshwater Lakes and Reservoirs

This project - financially supported by the U.S. Army Corps of Engineers - is a collaboration between the PEARL Environmental Economics Team (Dr. Scott Knoche, Dr. Kehinde Ojo, and Anjali Gulati) and researchers from UMCES CBL (Dr. Lisa Wainger) and UMCES IMET (Dr. Al Place). This project uses a diverse range of economic tools - including return-on-investment and benefitcost analysis - to estimate the benefits of controlling harmful algal blooms (HABs) in U.S. freshwater lakes and reservoirs. Tasks associated with the project include a comprehensive assessment of the past and potential future socioeconomic impacts of HABs in these waterbodies. A key output will be a national-scale estimate of the economic benefits resulting from reduced HAB intensity and spread. Ultimately, this project will provide valuable insights that will help guide the effective management of HABs across freshwater ecosystems throughout the U S safeguarding the health of aquatic environments and communities nationwide

Partnership to Advance

This two-year project, supported by NOAA Aquaculture, provides funds to the PEARL Environmental Economics team to hire and train a graduate student at Morgan State University in a broad array of aquaculture economics techniques. In Year 1, the student will develop a concept for a research project that addresses key aquaculture economics questions. In Year 2, the student will carry out the research project while co-mentoring an undergraduate student as part of the MSU PEARL Summer Internship program.

Soft-Shell Clams

The Ongoing Battle to Combat Heat-Related Summer Mortality

The warm water that is present in Maryland can be a double-edged sword for culturing soft-shell clams. On the one hand, it can facilitate increased clam growth compared to those clams grown in New England. On the other hand, the peak heat of the Maryland summer is typically fatal to clams that are raised in aquaculture gear, as this prevents farmed clams from burrowing deep into sediment to evade heat as they would do in their natural environment. Our previous research reveals that soft-shell clams can reach 1.8 inches in length during a 7.5 month period. With this in mind, our theory is that we can increase the size of harvested clams by deploying them earlier, allowing them more time to grow before summer mortality becomes an issue. Producing clams that measure 2 inches in length is an important metric, as this is the legal harvestable size for the Maryland wild clam fishery.

Tothisend,theaquacultureteamperformedaheattoleranceexperimentinSummer2023toidentifythe lethaltemperaturethresholdforclamsofdifferentageclasses.Theseresultsareintendedtoguide optimaldeploymentandharvesttiming.Resultsshowedthatsoft-shellclamseedarehighlytolerantto temperaturesover30°C(86°F),exhibitingahighsurvivalrateof98%.Ontheotherhand,allone-year-old juvenileandadultclamsperishedwhenexposedtothesametemperaturesintheheattolerance experiment.

The above results suggest clam seed could be deployed in high temperatures (July or August) and then harvested in June or early July the following year before water temperatures reach lethal levels. Our newly tested clam seed that were deployed in August 2023 have exhibited fast growth. By midMarch 2024, the average shell length reached 39.5 mm (1.55 inches) with the largest shell length measuring 43.24 mm (1.7 inches). Based on this information, we believe it’s possible for these soft-shell clams to exceed two inches in length by the end of May 2024.

2024 Soft-Shell Clam Spawning Season

PEARL’s Aquaculture Team initiated spawning this March, successfully producing millions of soft-shell clam larvae. The clams have since completed their metamorphosis and have transformed into clams you can finally see with the naked eye! This is the fourth year of successfully spawning softclams - the Team has the system down pat! The newly produced seed will be used in a research project that examines the effectiveness of different grow-out methods at several farms. Some clams will also be used for a project that seeks to identify the heat tolerance of the soft-shell clams. To see updated pictures and videos of our soft-shell clams, make sure to follow our social media accounts:

Oysters & Genomic Selection

PEARL’s Dr. Ming Liu has developed a genomic selection model to identify desirable traits, specifically for high survival and growth, focusing on the Patuxent River wild oyster population. Earlier this year, the Aquaculture Team sampled over 300 wild oysters and sent them to a lab for genetic testing to identify which oysters possess the genes we are looking for. The resulting genetic information and the selection model will be used to determine which oysters are among the top 10% that possess the desirable traits (high breeding values) and thus will be used as parents for spawning to produce fast growing, low-salinity tolerant oyster lines. The Aquaculture Team plans on validating the effectiveness of the selection model by producing the oyster lines in May 2024 and evaluating their performance in the field.
