What is the stuff that a male fish puts on some eggs from lady?

The stuff that a male fish puts on some eggs from a female is called milt. Milt is the sperm of a male fish.

Here's a breakdown of the process:

* Spawning: The female fish releases eggs into the water.

* Fertilization: The male fish releases his milt over the eggs, and the sperm swim to fertilize the eggs.

* Development: Once fertilized, the eggs develop into embryos and eventually hatch into young fish.

The process of fertilization can vary depending on the species of fish. Some fish species lay their eggs in nests, while others release their eggs and sperm directly into the water.
