Seventy percent of an adult rockfish's diet historically has been filled by menhaden. Today that's down to eight percent. What is causing the menhaden population to plummet and what can we do about it? The State of the Bay Report makes it clear that the Bay needs our support now more than ever.

But menhaden reproduction in the Chesapeake Bay remains a concern, and many are being caught by an industrial fishing fleet to create fish feed, fish oil pills, and other products.
Low oxygen levels. Pollution flowing into the Bay feeds large algal blooms, which suck up oxygen when they die and decompose. Maryland Sea Grant has program development funds for start-up efforts or strategic support for emerging areas of research.
