The release of fish eggs and their subsequent fertilization is called spawning. Most marine fish reproduce by releasing thousands of small eggs into the water for external fertilization. Egg-laying fish have a variety of methods for releasing the eggs. Some fish scatter eggs, which are fertilized by the male fish as they fall. Other fish attach the eggs to a surface, where they are then fertilized as they are released. Some fish release eggs into a nest of bubbles blown by the male fish.
Oxygen levels of the water, availability of food, size of each fish, age, number of times the fish has spawned before and water temperature are all factors known to effect when and how many eggs each carp will spawn at any one time.s a verb, spawn refers to the process of releasing the eggs and sperm, also called spawning. Most aquatic animals, apart from aquatic mammals, reproduce through a process of spawning. Spawn consists of the reproductive cells (gametes) of aquatic animals, some of which will become fertilized and produce offspring.
