Q.Distinguish between milt and spawn.

Milt and Spawn (Fish Reproductive Products)

Most bony fishes reproduce by external fertilisation — the egg and sperm meet outside the body, in the water. This shapes a lot of their biology, and two special terms describe the reproductive products they release.

Why external fertilisation needs special terms

On land, fertilisation happens inside the female's body, so sperm and eggs are transferred directly. In water, a fish cannot deliver sperm precisely, so both sexes shed enormous numbers of gametes into the surrounding water at roughly the same time and place. Success depends on quantity and timing rather than accuracy — which is exactly why fishes produce their gametes in bulk, with their own names.

Milt

Milt is the whitish, milky seminal fluid released by the male fish — it contains the sperms suspended in fluid. When a male "releases milt," he is discharging a cloud of sperm into the water over the eggs.

Spawn

Spawn is the mass of eggs released by the female fish. A single female may shed hundreds or thousands of eggs at once as a sticky or floating mass. The very act of releasing eggs and milt together is called spawning.
