For reasons we can’t decipher, we’ve received a few questions lately about rearing worms. The most recent article we wrote dealt with raising marine worms, and the question before us now has to do with rearing polychaete worms (or simply “polychaetes”) specifically. (Most polychaetes are marine worms, so obviously raising marine worms and raising polychaetes are related.) What exactly our reader was asking was hard to determine, but at bottom it was about managing what might be called a “polychaete worm farm,” one in which polychaetes are reared and bred. Is it possible to rear and breed polychaete worms?
