People also ask
Do fish lay eggs or give birth?
Yes, a fish gives birth and lay eggs in large number. Like all living organisms, the fish breed and reproduce babies to increase in number. Some fish are liver-bearers that give birth to babies, and some are egg-bearers that lay eggs. The usual counts of eggs range between 50 ?100000 in number while the number of babies ranges between 2-50.
How many eggs do fish lay in a year?
Some fish in fast-flowing rivers like rainbow trout spawn once a year, and a 13-inch female can produce up to 3 000 eggs over the course of one spawning (which usually lasts a few days). On the other hand, a female brook trout can produce only around 100 eggs in the first year of life, but a 3yo female can lay between 500 ?1 000 eggs.
What fish lay eggs in an aquarium?
Egg depositors, too, can be divided into two groups ?those that look after their eggs and those that don. They are many species of tropical fish like goldfish, barbs, and tetras that can lay eggs in an aquarium under optimal conditions.
What happens to fish eggs when they hatch?
Fish eggs. Fish breed in a number of ways. Most fish release thousands of eggs, scattering them in the water where the male fish fertilize them. The eggs develop and hatch into larvae (baby fish) without any help from the parents. Most larvae are eaten by other creatures, but a few survive to become adults.
