Students will gain a better understanding of the marine food chain and how fish are adapted for consuming algae and other organisms. This, in turn, will provide a better context for the origin of omega-3 fatty acid production in the marine ecosystem. Students will be able to make connections to the marine food chain and it's significant role in the health of our oceans and our society.
Students will be introduced to a common producer in the marine environment by examining a live algae sample under the microscope.
Students will gain a better understanding of the importance of Menhaden in Chesapeake Bay and it's connection to consumer science.
Students will make connections between the value of the menhaden fishery and fish oil products produced by different manufacturing processes.
