Abstract

The reproductive strategies in fish varies widely. However, the majority of them release a large amount of unfertilized eggs into the water. Simultaneously, the male fish releases a large amount of sperm which fertilizes some of the released eggs. Mainly, the reproduction methods of the fish can be divided into two methods. In the first method the female fish releases eggs either on the leaves of the sea plants or on the seabed. In the second method, the male by using the anal fin as a copulative organ introduces sperm into the female; therefore, the eggs are fertilized internally. Consequently, the female delivers live fry. The aim of the present study is to present a review of the reproductive, spawning and sexual strategies in fish.
