What does milting mean?
Milting is a specialized verb in fisheries and aquaculture meaning to fertilize fish eggs with milt, the sperm of a male fish. It can also refer to the controlled application or collection of milt during artificial breeding, a practice in which sperm is obtained from a donor fish and used on eggs that may be kept in a hatchery. The word belongs to technical and literary descriptions of reproduction rather than everyday conversation. Its spelling and pronunciation can cause confusion with melting, which involves turning a solid into a liquid through heat, and with milling, which means grinding or processing in a mill. Despite its narrow use, milting points to an important feature of fish reproduction: eggs and sperm normally meet during spawning, but breeders can separate those events. The term is therefore useful when discussing managed breeding, sperm collection, and the reproductive biology of fishes.

Where does milting come from?
Milting comes from milt, the verb meaning to fertilize eggs with fish sperm. Milt itself continues an English word recorded in Middle English and Old English, ultimately associated with Proto-Germanic *milz and an Indo-European root connected with crushing or grinding. A related form is milter, a male fish with mature sperm, while meal belongs to the same ancient grinding root through its sense as ground grain.
