There are nearly 3,000 plant and animal species in and around the Chesapeake Bay (Murdy, 1997). Five major categories of fishes occupy the Chesapeake Bay area: freshwater, marine, anadromous, and catadromous (Murdy, 1997). There are more than 25,000 species of fishes alive and present in our world (Helfman,1997). About 267 species of fish visit the waters of our Chesapeake Bay as permanent residents, spawning migrants, and seasonal visitors (Murdy, 1997). Of these 267 fish species, only 32 species are year-round residents of the Bay. (Murdy, 1997).
In this activity, students learn details about fish species in the Upper, Middle, and Lower Chesapeake Bay. The students will observe data from the three areas of the Chesapeake Bay. The students will analyze data, compare fish species, organize facts, categorize fish, and formulate research about the fish species. The students can make hypotheses about fish populations, food webs, trophic interactions, key tributaries of the Chesapeake bay, and much more.
These activities allows students to explore research issues involving the Chesapeake Bay. Students could dive into topics of their interest. Students could discover details about : fish species; fish weight; fish length; diversity of species in the Upper, Middle, and Lower Chesapeake bay; water characteristics in various areas; and a multitude of other issues. This activity can challenge your students to think like scientists.
Chesapeake Bay Research from CHESFIMS 2005
Researchers from the Chesapeake Biological Laboratory (CBL) in Solomon’s Island collected data from the Chesapeake Bay (CB) during a research program called CHESFIMS (Chesapeake Bay Fishery Independent Multi-species Survey). Using scientific equipment, characteristics of the Bay were documented by conducting tests including dissolved oxygen (DO), salinity (S), water temperature (WT), water depth (WD), and fish species at various sites. CHESFIMS has been an ongoing 8-year survey of the Chesapeake Bay environment. CHESFIMS has five specific objectives:
-Conduct a Bay-wide survey of the bentho-pelagic fish community, focusing on young (juveniles & yearling) fishes in the mainstem of the Ches. Bay.
-Design and implement a complementary survey of the bentho-pelagic fish community in the extensive shoal habitats (< 5 m depth) in the mainstem of the Chesapeake Bay.
-Conduct pilot surveys of the pelagic fish community in key tributaries and in the mainstem to generate sampling statistics
that will of use in
subsequent design improvements.
-Determine trophic interactions among key components of the pelagic fish community, & examine the implication of the relationships uncovered in empirical studies using bioenergetic modeling.
-Conduct statistical analyses of existing and new data to optimize the complemented pelagic survey with respect to consistency & accuracy of key parameters.
Scientists will organize CHESFIMS data and report outcomes to various government agencies. Teachers and students can interpret and evaluate the CHESFIMS data. Numerous labs & demonstrations will allow students to think like a scientist. When students research various fish, identify fish, summarize facts about fish, and analyze the importance of fish in various food chains; they are thinking like scientists. This information can provide students the opportunity to engage in learning authentic and realistic statistics about our bay. Enjoy the fish facts. Ichthyology Rules!
Scientists are constantly analyzing information about the Chesapeake Bay (CB). Various agencies are concerned about different aspects of the bay. The goal of CHESFIMS is to assist scientists with their understanding of the CB. The research can help answer questions like “Is the CB in a state where life is sustainable? Are organisms flourishing in the CB environment? What factors might influence the survival of a species in the Lower bay? How are fish populations different in the Upper, Lower, and Middle CB? What questions might you ask about the CB?

"Got Fish Species?"
is a lesson promoting student discovery and
scientific reasoning. Students will participate in activities about the
Upper, Middle, and Lower Chesapeake Bay research. Students will
determine patterns and information using 2005 research from a program
called CHESFIMS (Chesapeake Bay Fishery Independent Multi-species
This lesson has an array of authentic research about our Chesapeake Bay. The information provided can be overwhelming, but it is exciting data about our Bay.
The goal of this activity is to create curiosity and enthusiasm for aquatic research. The information provided can be calculated, summarized, reviewed, organized, and altered to fit the needs of your students. If you follow the charts and lesson, you will build a sense of Chesapeake Bay awareness in your students. Enjoy "Got Fish Species?"
