At that place are dissimilar stages of a young fish's life. They are referred to by many names throughout the kickoff years of their survival. Depending on the species will decide what stages and names a baby fish are referenced by. This tin include egg, yolk-sac larvae, fry, and juvenile before reaching maturity.

Reproduction

At that place are three ways for a fish to reproduce. This is either through livebearing, which is similar to the way humans and other mammals produce their young, spawning, or self-bearing.

Spawning is the process when the female person fish releases her eggs. The eggs are either deposited direct into the water, where they float effectually, or into a nest. This depends on the type of fish species. The male person fish volition then fertilize the eggs with milt that they release. Non all eggs that are laid will be fertilized. Depending on the species of fish, the fish will spawn every year, every four years or only one time in their lifetime earlier dying.

Some fish tin switch genders. This allows them to consummate the entire process of reproduction themselves. This process is also known equally cocky-bearing.

Eggs

Fertilized eggs hatch in two to eight days, depending on the species of fish. The majority of eggs don't accomplish maturity due to the different threats they face. Some of these threats include the change in h2o temperature that can occur due to the changing seasons during spawning. Oxygen levels irresolute in the water is another common threat to fertilized fish eggs. Flooding and sedimentation that carry the eggs to unhealthy areas or crusade them to become landlocked volition preclude the egg from hatching. Predators and illness are a constant threat to fish at all stages of their lifecycle.

Larvae

The larvae stage for a baby fish begins nine to eighteen days after the egg has hatched. This is also called the yolk-sac phase as the yolk-sac stays attached to the baby fish once it is hatched. This yolk-sac provides the young fish with the nutrients it needs to abound within its environment. Some species of fish, such as the catfish, do not go through this stage.

The larvae phase of the baby fish's life lasts ane to 2 weeks. During this time, information technology feeds off the yolk-sac while staying at the lesser of the water. When in the larvae stage, many species of fish tend to settle within the plants and other caverns at the bottom of the water for protection. This helps them blend in and hide from predators every bit they don't accept fins for pond and are classified as gratuitous floaters.

Fry

As a fry, a young fish yet has its yolk-sac fastened, but it begins to diminish in size. The fry phase lasts for 2 to five days for well-nigh types of fish. The fry volition stay at the bottom of the water during this fourth dimension. However, it does brainstorm to explore its new surroundings, coming out of hiding for short periods of fourth dimension. Most of a fry'southward nutrition comes from the remaining yolk-sac, but it will begin feeding on food lying at the bottom of the water'due south bed.

Juvenile

Equally with each phase of a fish's life cycle, the corporeality of time the baby fish remains a juvenile depends on its species. This stage may last up to three years. The juvenile fish begins to develop its fins, and their gills mature throughout this stage. Juvenile fish are not able to reproduce. The beginning of the juvenile stage is crucial to the fish's survival, equally it must acquire how to survive amongst its predators, find plenty food to survive and gain its independence in all other aspects.
