How do zebra fish breed and how they give birth to fry?

Zebrafish breed through external fertilization, where the female lays eggs in water, and the male fertilizes them shortly after. The female can lay hundreds of eggs at a time, which typically hatch within 2-3 days, depending on water temperature. Once the eggs hatch, the small, free-swimming larvae, known as fry, emerge and begin to feed on their yolk sacs before transitioning to external food sources. Zebrafish are known for their prolific breeding and rapid growth, making them popular in scientific research and aquaculture.
