Nаme twо exаmples оf pаrasites we have cоvered in the class and the phylum to which they belong.
Oysters hаve а lоng histоry оf use, аnd we focused in class on the oyster industry in New York. From peaks of harvesting and production in the 1860s–1880s, oyster fisheries declined precipitously. What were the processes that led to the decline of oyster fishery in New York? Were declines synchronous (at the same time) in the Chesapeake Bay and if not, what is the trend in the Chesapeake over the last century? What is the general assessment of oyster health globally, and what are the signs of human responses to these problems? What are some other values for oysters beyond food value? Finally, describe some responses we are taking now to bring oysters back into New York Harbor.
