I do support the petition to pause purse-seine fishing for Menhaden  in the Chesapeake Hay until there has been a rebound in the population of rockfish. Rockfish support a broad base of the economy in the entire bay region not just one locality. 
Additionally, it appears that populations of Osprey are falling due to a lack of Menhaden available for them to feed their young as food.   
I can remember in my past seeing vast schools of Menhaden boiling on the surface and being chased by schools of striped bass.  I spent a lot of time on the Bay this year and never saw this occur. It is a collapse of the food chain in the Chesapeake Bay due to the overfishing of menhaden  by omega protein.
