Explanation: 

Detailed explanation-1: -Fish reproductive system Like most vertebrates, it’s necessary for an egg and sperm to combine for fish to create new life. Although there are several ways in which that can happen, the common denominator is the fish’s reproductive organs: the testes and ovaries.

Detailed explanation-2: -In most cases, the females release eggs into the water and they are immediately fertilized by sperm from the male. In the wild, fish can easily reproduce when they sexually mature.

Detailed explanation-3: -Some species of sawfish can reproduce without a mate. Scientists documented a series of “virgin births”, reproduction without mating, in a critically endangered sawfish species pushed to the brink of extinction by over-fishing and habitat destruction in 2015.

Detailed explanation-4: -Some species need only one to reproduce-themselves! Unisex fish can reproduce without the other sex present. Unisex fish are always female and reproduce only females. They do mate with males of similar species, but the sperm never contributes to the heredity of the offspring.
