This law sets up a government-run buying program for blue catfish, an invasive fish overrunning the Chesapeake Bay, so watermen (people who fish for a living) have a guaranteed buyer for their catch. NOAA, the federal agency that oversees ocean and fisheries issues, would arrange deals with companies that make pet food, animal feed, or fish-farm feed, so those companies commit to buying the caught catfish, and NOAA would set a minimum price per pound so fishermen know what they'll get paid. Before any of this buying starts, scientists working with NOAA have to first count roughly how many blue catfish are actually in the bay and publish that number, so there's a clear baseline for tracking whether the effort is shrinking the population over time.
