Milt is the seminal fluid of fish, mollusks, and certain other water-dwelling animals which reproduce by spraying this fluid, which contains the sperm, onto roe (fish eggs).

Milt or soft roe also refers to the male genitalia of fish when they contain sperm, used as food. Many cultures eat milt, often fried, though not usually as a dish by itself.

In Indonesian cuisine, the milt (called 'telur ikan') of snakehead and snapper is usually made into 'kari' or 'woku'.

In Japanese cuisine, the milt ('shirako') of cod ('tara'), anglerfish ('ankō'), salmon ('sake'), squid ('ika') and pufferfish ('fugu') are a delicacy.

In Korean cuisine, the milt of Alaska pollock, cod, blackmouth angler, bogeo, and sea bream are considered a delicacy.

In Romanian cuisine, the milt of carp and other fresh water fish is called 'Lapți' (from the Latin word 'Lactes') and is usually fried.

In Russian cuisine, herring milt ('Moloka') is pickled the same way as the rest of the fish, but eaten separately, sometimes combined with pickled herring roe. Various whitefish soft roes are usually consumed fried and it is an inexpensive everyday dish.

In Sicilian cuisine, the milt of tuna is called 'Lattume' and is used as a typical pasta topping.
