Dr. Daphne Munroe presented her research at the March 13, 2013 Ocean Lecture & Educators’ Night. Dr. Munroe discussed what the biology of local shellfish species, how we management our shellfish fisheries, and what science goes into the fisheries management. Following the lecture, we shared lesson plans related to shellfish biology and fisheries as well as discussed how to bring these topics into your classrooms/clubs. The evening culminated with an information/activity exchange during which educators shared with each other activities they are currently using in their classrooms to teach about shellfish, fisheries, and/or modelling.
Below we have included a summary of Dr. Munroe, Background Materials, the evening’s broadcast, .pdf of the science presentation, and adapted Lesson Plans to teach on the topics of shellfish biology, fisheries, and modelling.
Enjoy! The East Coast MARE Team
Dr. Daphne Munroe –
Dr. Daphne Munroe is an Assistant Research Professor at Rutgers University. She received her PhD from the University of British Columbia. Dr. Munroe is primarily interested in the ecology of marine larvae and coastal population dynamics. Her specific research interests include the interactions of anthropogenic coastal activities on larval recruitment processes and understanding linkages between larval recruitment and subsequent population dynamics.
Background Materials-
We will compile the following materials as optional background information if you wish to read about the topics that were covered during the event and included in the adapted lesson plans below.
Fisheries in General: The NOAA summary document, Status of Stocks 2011: Annual Report to Congress on the Status of U.S. Fisheries, provides a good overview of the current status of U.S. fisheries stocks. Fisheries of the United States (Kim Iverson and Anna Martin 2009) There are a lot of fisheries resources on the Dr. Olaf Jensen OLEN Background Materials Section. Oyster Fisheries: A recent paper presents the first quantitative and comprehensive estimate for the declines in wild oyster habitats across the U.S. “Historical ecology with real numbers: past and present extent and biomass of an imperilled estuarine habitat” (2012) Proc. R. Soc. B 279:3393-3400. The Wallstreet Journal has an interesting article about the NJ oyster fishery, “Planting Seeds for a Better Oyster Harvest: New Jersey, Once Home to a Thriving Shellfish Industry, Uses Advanced Growing Techniques to Boost Delaware Bay’s Output” (January 27, 2013) The Nature Conservancy developed a Fact Sheet about Shellfish Reefs at Risk: A Global Analysis of Problems & Solutions based upon the “Oyster reefs at risk and recommendations for conservation, restoration and management.” BioScience 61:107-116 (2011) paper that was highlighted in the Spring 2012 East Coast MARE Newsletter: What’s Hot in Ocean Science. Surf Clam Fisheries: The Northeast Fisheries Science Center page on Status of Fishery Resources off the Northeastern US: Atlantic Surf Clams contains information about the biology and fishery of Atlantic Surf Clams. The New Jersey Department of Environmental Protection provides a summary of the trends in local Surf Clam fishery over the past few decades in the Wildlife Populations: Surf Clam.Fisheries & Shellfish Fisheries:
Oysters: The Chesapeake Bay Office of NOAA has an Oyster Fish Facts page offers information about oyster biology, the fishery, and more. Similarly, the Maryland Department of Natural Resources has a Maryland Fish Facts: Eastern Oyster page with biology and fun facts about oysters. The South Carolina Oyster Restoration & Enhancement program has a good image and description of the life cycle of oysters on their Oyster Biology & Ecology page. Maryland Sea Grant provides an extensive overview of oyster biology in the Biology of the Oyster document. Surf Clams: The NOAA FishWatch page on Atlantic Surf Clams includes lots of good information about the biology, fishery, science, etc. The Essential Fish Habitat Source Document:Atlantic Surf Clam, Spisula solidissima, Life History and Habitat Characteristics (NOAA Technical Memorandum NMFS-NE-142) provides a summary of known information about the biology and habitat requirements of Atlantic Surfclams. The Northeast Fisheries Science Center page on Status of Fishery Resources off the Northeastern US: Atlantic Surf Clams contains information about the biology and fishery of Atlantic Surf Clams. Molluscs: Man and Mollusc is a website with many articles and lesson plans about mollusks for teachers K-12.Shellfish Biology:
Seeds of Science/Roots of Reading has a strategy guide that introduces the approach for teaching about how scientists use models, “Teaching About How Scientists Use Models with Planetary Science.” NASA has a strategy guide to use the article “What Makes Up Most of the Solar System?,” which includes two diagrams that model the relative scale and emptiness of the Solar System to introduce students to why scientists use models. JSSS put together a Teacher Support Materials on “Using Models in Science Teaching and Learning” to describe types of models, science thinking skills associated with making/using models, and examples of models and analogies used in science teaching.Scientific Modelling in the Classroom:

Additional Data Resources-
The Alaska Fisheries Science Center has a great explanation of how scientists age fish and what they do with the data on the Age and Growth Homepage. Additionally, they have an interactive Age and Growth Data website in which you can select a species of fish and the year to plot the age and length data from the survey samples. You can overlay bottom temperature and strata as well onto the map. [To make a graph of the data select a year, a species, and then use your mouse to highlight the points/sampling locations that you want to include in the graph. The data will plot on the graphs to the right.] This enables you to create graphs similar to this example.
