Like every other animal on this planet, fishes also grow large enough to reproduce. We can divide the life cycle of a fish in 5 stages. These 5  stages are common in almost all the different species of fish.

​

Stage 1

• Egg: In this stage, the embryo is formed inside the hardened egg, once the egg is fertilized. Then it will start to develop organs. After this, eyespots and tail are completely developed. Species living in warmer water hatch faster as compared to the species living in colder water.

​

Stage 2

• Larvae: Once the eggs are hatched, they are known as larva. New larvas have a yolk sac. This yolk sac is the nutrition source for them. The larva can survive for 2-4 days by their yolk sac food supply.

​

Stage 3

• Fry: The young fish are called fry once the yolk sac is fully absorbed. In this stage, they are ready to start eating on their own. 

​

Stage 4

• Juvenile: Metamorphosis is the process that marks an end point on the larval stage. In this phase, fishes acquire characteristics of an adult fish such as fins. Most fish do not survive to become adults. Threats to survival include changes in water temperature and oxygen levels, competition for habitat and predators.

​

Stage 5​

• Adult: – In this stage, fish are able to reproduce. Females release the eggs in water and males release milt that helps to fertilize the eggs.
