Most Fish breed by shedding their eggs and sperm directly in water.

Fertilization itself is a risky business.

A female cod fish may lay more than 6 million eggs each breeding season.

Of these only one or two will grow to become adults.

Fertilized eggs as well as the young fish are eaten by the sea creatures.

To compensate for this high casualty rate, most fish species lay large number of eggs.

Female turbots have been found with up to 9 million eggs in their ovaries.

A ling fish once was found to have 28 million eggs in her ovary.
