MILT, or Melt, in natural history, the soft roe in fishes; thus called by reason it yields, by expression, a whitish juice resembling milk. See ROE.

The milt is properly the seed or spermatice part of the male fish. The milt of a carp is reckoned a choice bit. It consists of two long whitish irregular bodies, each included in a very thin fine membrane. M. Petit considers them as the testicles of the fish wherein the seed is preferred; the lower part, next the anus, he takes for the vesicula seminalis.
