There are different stages of a young fish's life. They are referred to by many names throughout the first years of their survival. Depending on the species volition make up one's mind what stages and names a baby fish are referenced by. This can include egg, yolk-sac larvae, fry, and juvenile before reaching maturity.
Reproduction
There are three means 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 fish releases her eggs. The eggs are either deposited directly into the water, where they float around, or into a nest. This depends on the type of fish species. The male fish will then fertilize the eggs with milt that they release. Not all eggs that are laid will exist fertilized. Depending on the species of fish, the fish will spawn every year, every four years or merely once in their lifetime before dying.
Some fish can switch genders. This allows them to complete the entire process of reproduction themselves. This process is likewise known as self-bearing.
Fertilized eggs hatch in two to viii days, depending on the species of fish. The majority of eggs don't accomplish maturity due to the unlike threats they face. Some of these threats include the change in water temperature that can occur due to the irresolute seasons during spawning. Oxygen levels irresolute in the water is some other common threat to fertilized fish eggs. Flooding and sedimentation that acquit the eggs to unhealthy areas or crusade them to become landlocked volition foreclose the egg from hatching. Predators and disease are a constant threat to fish at all stages of their lifecycle.
Larvae
The larvae stage for a baby fish begins 9 to 18 days later on the egg has hatched. This is also called the yolk-sac phase as the yolk-sac stays attached to the baby fish once information technology is hatched. This yolk-sac provides the young fish with the nutrients it needs to grow within its environs. Some species of fish, such every bit the catfish, do not go through this phase.
The larvae stage of the babe fish'due south life lasts one to two weeks. During this time, it feeds off the yolk-sac while staying at the bottom of the water. When in the larvae phase, many species of fish tend to settle inside the plants and other caverns at the bottom of the water for protection. This helps them alloy in and hide from predators as they don't accept fins for swimming and are classified as gratuitous floaters.
Fry
As a fry, a immature fish still has its yolk-sac attached, simply it begins to diminish in size. The fry phase lasts for two to 5 days for most types of fish. The fry will stay at the bottom of the h2o during this fourth dimension. Withal, it does begin to explore its new surroundings, coming out of hiding for brusque periods of time. Virtually 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'southward bed.
Juvenile
Every bit with each stage of a fish's life cycle, the amount of fourth dimension the babe fish remains a juvenile depends on its species. This stage may last up to 3 years. The juvenile fish begins to develop its fins, and their gills mature throughout this phase. Juvenile fish are not able to reproduce. The beginning of the juvenile stage is crucial to the fish'southward survival, as information technology must learn how to survive among its predators, find plenty food to survive and proceeds its independence in all other aspects.
