16. The Hudson River Shad
The Hudson's food webs support a great number of fishes. Most important to people are the anadromous species - those that are born in fresh water but spend most of their lives in the ocean.
The American shad swims upriver to spawn every year in early spring. This large herring once supported the most important commercial fishery on the Hudson. However, its numbers have declined to the point where DEC had to close the fishery in 2010. The agency is implementing an American shad recovery plan to restore the population.
