What is the life cycle of fish?

The life cycle of fish typically involves the following stages:

1. Egg:** Fish begin their life as eggs. These eggs are laid by the female fish and fertilized by the male fish. Fish eggs are usually small and round, and they are often covered with a protective coating.

2. Larva:** After the eggs hatch, the fish enter the larval stage. Larval fish are small and free-swimming, and they often have a very different appearance from adult fish. They typically feed on plankton and other small organisms.

3. Juvenile:** As the fish grow larger, they enter the juvenile stage. Juvenile fish begin to resemble adult fish, but they are still not sexually mature. They feed on a variety of organisms, including insects, worms, and small fish.

4. Adult:** Adult fish are sexually mature and can reproduce. They typically have a larger size and a more developed appearance than juvenile fish. Adult fish feed on a variety of organisms, including insects, worms, fish, and plants.

Some fish, such as salmon, go through a process called anadromy, in which they migrate from freshwater to saltwater and back again to spawn. Other fish, such as trout, are semelparous, meaning they die after spawning.
