How Do Fish Reproduce?
Basically there are two ways in which fish reproduce:
Live Bearing : In this process the female fish is internally fertilized by male fish and the female carries the fry for about a month before delivering the baby. After delivery, the baby swims away and starts searching for food. Some examples of live bearers are: half beaks, mollies, swordtails, guppies and platies. In these species the female is comparatively larger than the male. The male has a rod like anal fin called gonopodium which is used for internally fertilizing the fish. Egg laying: The egg laying process may take around 7-10 days. This process is also different among different species.
So, these are the different ways in which the fish reproduce and they are surely as surprising as the creature itself. Adult fishes reproduce in the similar way as the higher animals. The male fish produces sperms while the female fish produces eggs. These sperms and eggs combine to form a new individual which contains all the genetic matter which comes from both parents. Depending on the species, the eggs can be fertilized internally or externally. Some of the marine fish species are hermaphrodites. Hermaphrodites are the species that have both female and male reproductive organs.

The first fish appeared in the sea 470 million years ago. Today, more than 20,000 species of fishes have been identified ranging from the great whale shark to the pygmy goby. Fish live in fresh water streams, rivers and lakes and in salt water seas and oceans. Different kinds of fishes have different ways of reproduction some lay eggs while some carry them in their mouths while some are internally fertilized by the male fish. Although most fish leave their eggs and young to look after themselves, some species protect their young.
