Polychaetes are a variety of worms. The worms Delta Farms produces are the ragworm (N. Virens). Nereis virens is a scavenger that will eat dead and live animal or plant matter. The ragworm reproduces once in its life and dies after reproduction. An average female can contain over one million eggs, but a record (wild) female was found to contain 7 millions eggs.

Nereis virens is found in Northern Europe (UK, Ireland, Holland, Germany, Denmark) and the North Eastern coasts of the US (Maine) and Canada.

Polychaetes are mainly used as part of the shrimp maturation diet. Feeding polychaetes to shrimp broodstock is essential for the maturation and spawning. Polychaetes are also used as bait in sport fishing.
