The number of young produced per batch by fish varies enormously by species. Fish that provide more care or retain the eggs longer, such as mouth brooders and live bearers, produce very small numbers of young, 10 or 20 perhaps. Some sharks only produce one or two young at a time.

Other fish which, such as most broadcast spawners in the open ocean, can produce thousands upon thousands of eggs per breeding cycle.
