The oldest type of net used by the Chesapeake Bay watermen is called a pound net. Wooden stakes are pushed into the bottom of the Bay, spaced apart in a line that runs across the tide. Nets are strung between the stakes and along the bottom of the river, making a fish trap. In late February the pound netter starts to put in the stakes. By the middle of March he will set his nets and start fishing. Each day the waterman goes out to the pound net and scoops the fish out with a hand net. He will not remove the pound net, except for many repairs, until November.

These traditional boats tended to the oyster fleets working the beds in the Bay, buying harvested oysters from the oystermen in the afternoon, and running those oysters to faraway markets and rail centers in Norfolk, Crisfield, Baltimore, and Washington DC, and to local shucking houses and canneries around the Bay.

This nematode worm is a parasite, originally from Southeast Asia. With the American eel population already declining, the introduction of this nematode may have a large negative impact on the survival of this species.
Anguillicoloides crassus (Nematode Worm)
Pickleweed is an invasive or introduced plant in Hawaii. It has succulent, brilliant green leaves and is common in salt marshes and tidal shorelines. It grows slowly in soils with high salt concentrations and areas with seawater overwash where it suffers little competition from other plants. The species manages salts by sequestering them in cell vacuoles and eventually shedding the leaves.
