📖 Overview
Milt refers to both the sperm and the fluid that carries it. External-fertilising fish release milt into the water to fertilise released eggs; internal-fertilising species deliver it via claspers or gonopodia. Milt is consumed as a delicacy in Japan (shirako) and eastern Europe.
⚙️ Function
Sperm transport medium; contains motility-activating chemicals released upon contact with water.
✨ Fun Fact
Shirako - cod, monkfish, or salmon milt - is a premium winter delicacy in Japan, valued for its custardy texture and briny sweetness.
