How are fish created without the birds and the bees answer?

Fish don't do the birds and bees thing. Momma lays several hundred unfertilized eggs in a cluster and poppa deposits his sperm on them. Fingerlings hatch and grow with no parental supervision.

Actually , the answer previous to mine is not entirely correct. That person forgot to take into account the live-bearing fish, such as poecilids, gooeids, and anablepids. In these fish, the male has a structure called a gonopodium, which is a modified anal fin. This organ is used much like a penis in "higher" animals. The male gets right up next to the female and injects her with sperm via his gonopodium. Sometime after fertilization, the female will give live birth to baby fish, called fry. Some of the well-known fish that fall into this group are guppies, mollies, and sWordtails.
