When breeding time comes, a large number of sperm cells accumulate in the ducts. At the same time, in the female’s genitals, represented by the paired number of ovaries and ending with the external duct, the eggs begin to ripen. As a rule, their number is directly influenced by both the type of fish, its size and even the years that have passed.
